Abstract:
Introduction. Modern antenna devices contain a large number of repeating elements. The process of development of CAD models of such devices requires repeatedly performed operations that is a routine task for an engineer. Therefore, the problem of repeating operations automation arises when constructing antenna models with periodic structures.Aim. To demonstrate the automation of slotted waveguide antennas design process in CAD Ansys HFSS.Materials and methods. In order to determine the dimensions of the slotted waveguide antenna the energy method was used. Automation procedure of the design of the slotted waveguide antennas in CAD Ansys HFSS using the Visual Basic Scripting Edition macros was presented.Results. In order to design and edit slotted waveguide antennas in CAD Ansys HFSS four macros in the VBScript language were established: for slot subtraction from a broad wall of a rectangular waveguide at given coordinates; for removing the original slots created using the previous macro; for drawing a polyline passing through the centers of the slots, in order to verify the antenna’s near field realized distribution; for inclined slot subtraction from a narrow wall of a rectangular waveguide at given coordinates. Results of the macros usage were presented.Conclusion. The above mentioned macros allow one to automate the routine steps during the process of creating and deleting objects while designing an antenna model with periodic structures in CAD Ansys HFSS. Specified procedures for creating macros could be extended to a wide class of tasks related to the studies of characteristics of electromagnetic structures including repeating objects (phased antenna arrays, reflective arrays, slotted waveguide antennas, fractal antennas, log-periodic antennas, multi-layer lens antennas, ladder-type microwave filters).

Abstract:
AbstractThe integration of plasmonic antennas on single-mode silicon nitride waveguides offers great perspective for integrated surface-enhanced Raman spectroscopy (SERS). However, the few reported experimental demonstrations still require multiple plasmonic antennas to obtain a detectable SERS spectrum. Here, we show, for the first time, SERS signal detection by a single nanoplasmonic antenna integrated on a single-mode SiN waveguide. For this purpose, we investigated a backscattering detection scheme in combination with background noise reduction, which allowed an optimization of the signal-to-noise ratio (SNR) of this platform. Furthermore, a comparison with the free-space SERS spectrum of the same antenna shows that the conversion efficiency from pump power to total radiated Stokes power is twice as efficient in the case of waveguide excitation. As such, we explored several important aspects in the optimization of on-chip SERS sensors and experimentally demonstrated the power of exciting nanoplasmonic antennas using the evanescent field of a waveguide. This observation not only is useful for Raman sensing but also could be beneficial for any process involving plasmonic enhancement.

Abstract:
The receiving antenna is an important part of a radio channel that requires electrodynamic approach in mathematical simulation of its characteristics. Since the invention of radio, and due to further theoretical studies of radio signal transmission, the following situation has arisen: researchers’ attention to receiving antennas is inversely proportional to the factor by which their number exceeds the number of transmitting antennas. We address the problem of building a receiving antenna electrodynamic model in terms of a waveguide representation of HF field. Structurally, the antenna is considered as metal wires of a finite length and arbitrary configuration. Current distribution in antenna is calculated using the long-line theory and normal-mode approach. The mathematical representation of the receiving antenna electrodynamic model is calculation expressions for receiving coefficients of normal modes. They reflect the effects of receiving antenna characteristics, including its directional pattern, on effectiveness of the incident HF field energy conversion into the energy of the driven current waves and final distribution of net current in antenna. These expressions are used to derive the expression to calculate the effective length of the receiving antenna. The obtained mathematical expressions of the receiving antenna electrodynamic model do not contradict the principle of antenna reciprocity. We present calculation formulas for the receiving coefficients and excitation of the isotropic antenna electromagnetic model.

Abstract:
This paper presents the investigation of on-body transmission single-band diamond dipole antenna with three different jackets. The jackets are named as normal jacket, grounding jacket and waveguide jacket. The on-body transmission is measured using two flexible single-band antennas attach to the jackets. A man with the height of 180 cm and 75 kg weight becomes as a model for the real measurement. The measurement is conducted in small space area by using portable network analyzer with flexible network cable. The measurement results show that the best performance for on-body transmission is with waveguide jacket. 10 dB transmission improvement is archived when the antenna is placed above the waveguide jacket compared to the normal jacket. It is found that the transmission of the antenna is also depends on the antenna orientation and further transmission lossess occur when the antennas are placed above the grounding jacket.

AbstractThis paper describes the design and characterization of a compact substrate integrated waveguide (SIW) fed antenna for the 122 GHz industrial, scientific, and medical band. The use of a single RO4350B substrate layer and the SIW feeding ensure a low-cost fabrication. Two versions of the antenna are presented differing in antenna gain and size. For measurement purpose, a transition from rectangular waveguide to SIW is introduced. Measurements of the radiation pattern have been performed and show good agreement with the numerical results for both antennas and an antenna gain up to 7.14 dBi.

Abstract:
Perfect magnetic conductors (PMCs) can help in the enhancement of antenna impedance bandwidth using their capability of reflecting the incident waves without phase reversal. The purpose of this paper is to show the advantages of using a perfect magnetic conductor in antenna engineering. The goal is to use it in waveguide-fed slot array antennas, increasing both the antenna impedance and radiation bandwidths. To this aim, a PMC-based rectangular waveguide composed of longitudinal slots is convenient. The impedance of the proposed array structure is calculated analytically. To compare analytical results with the simulation results, PEC- and PMC-based waveguide-fed slot arrays are designed and simulated in a certain frequency band. The simulation results are in good agreement with the theoretical predictions.

Abstract:
A general methodology for calculating antenna arrays with layered dielectric is considered. To demonstrate the proposed methodology, we consider the solution of the problem of radiation of linear waveguide array. Plane-parallel waveguides have a finite wall thickness. Antenna array scans in E and H planes. This problem is solved using Fredholm integral equations of the second kind. To solve the problem, the entire domain of the electromagnetic field is divided into partial intersecting regions An example of constructing Green’s functions of selected partial regions with allowance for their dielectric filling is considered. The formulation of the boundary-value problem for the antenna array in the form of Fredholm integral equations of the second kind using the technique of dividing the determination domain into partial regions with Green’s functions allows us to solve the following problem: calculations of the antenna array with dielectric plugs in the waveguides and with a dielectric coating over the antenna array. This technique allows optimization of dielectric parameters with the aim of aperture matching of the antenna array. The calculation results of the dependence of the reflection coefficient on the phase shift between waveguides in the H-plane are presented. The calculations are performed for different values of the dielectric constant of the plugs in the waveguides and the dielectric constant of the dielectric layer above the antenna array. The influence of the geometric dimensions of the plugs in the waveguides and the dielectric coating above the array is studied.

Abstract:
Wireless body area network (WBAN) applications have broad utility in monitoring patient health and transmitting the data wirelessly. WBAN can greatly benefit from wearable antennas. Wearable antennas provide comfort and continuity of the monitoring of the patient. Therefore, they must be comfortable, flexible, and operate without excessive degradation near the body. Most wearable antennas use a truncated ground, which increases specific absorption rate (SAR) undesirably. A full ground ultra-wideband (UWB) antenna is proposed and utilized here to attain a broad bandwidth while keeping SAR in the acceptable range based on both 1 g and 10 g standards. It is designed on a denim substrate with a dielectric constant of 1.4 and thickness of 0.7 mm alongside the ShieldIt conductive textile. The antenna is fed using a ground coplanar waveguide (GCPW) through a substrate-integrated waveguide (SIW) transition. This transition creates a perfect match while reducing SAR. In addition, the proposed antenna has a bandwidth (BW) of 7–28 GHz, maximum directive gain of 10.5 dBi and maximum radiation efficiency of 96%, with small dimensions of 60 × 50 × 0.7 mm3. The good antenna’s performance while it is placed on the breast shows that it is a good candidate for both breast cancer imaging and WBAN.

Abstract:
Substrate Integrated Waveguide (SIW) cavity backed antenna technology is a new form of transmission line facilitating the realization of non-planar (waveguide based) circuits into planar form for easy integration with other planar (Microstrip) circuits and systems. They retain the low copper and dielectric loss property of traditional metallic waveguides and are widely used in integration of walls, floors and flame redundant wearable. SIW-CB antenna is a perfect candidate for IoT based wearable antenna with FR4 substrate. In this sense we structurizean efficient small size antenna for IoT applications to operate in the range of 5 – 15 GHz. FR4-epoxy substrate is chosen so that the losses are minimized hence improving the efficiency. The proposed antenna resonates at 5.4, 6.9,9.1,11.5 & 14.2 GHz hence forming the Pentaband with a maximum return loss of 38.6 db. The other antenna parameter values are Gain 28.5 db, efficiency 90% and VSWR 1.

Abstract:
The research objective of this thesis is to provide a better solution for signal interference and reduce the size of waveguide antenna. The background investigations of different waveguide fabrication technologies and switch control methods are detailed in the introductory part of this thesis. Several novel substrate integrated waveguide (SIW) antennas for different purpose are demonstrated in the body of the thesis. The designs are mainly divided into two kinds. The first focuses on the switch beam SIW antennas working at 2.4 GHz frequency band. Compared to the corresponding waveguide antennas of multiple-input and multiple-output (MIMO), phased array and switch beam, the proposed SIW antennas have advantages in compact size, easy fabrication and high gain. By DC biasing the surface mounted PIN diodes, the waveguide slots radiate at diode-off state of reverse bias, and are shielded at diode-on state of forward bias. Based on different requirement, the SIW antennas can achieve two-direction, four-direction and six-direction transmission. The gain can be easily changed by extending the size of reflector walls. The second focuses on reducing the volume of SIW antennas, working at 5 GHz frequency band. A new folded SIW antenna is introduced. By folded the antenna front end part to second layer, the SIW antenna reduces the total length by the size of one-quarter guided wavelength. This folded antenna can radiate either monopole mode or dipole mode, based on the metal surface area. Another two new SIW antennas reduce the total length by directly cutting the front-end part at the slot center. By utilized the intrinsic coupling radiation, the SIW antennas use two half-length slots at different broad-wall plane to achieve 360 degree propagation and wide-band end-fire radiation.

Abstract:
An X band dual polarized slotted waveguide antenna array is designed with very high polarization purity for both horizontal and vertical polarizations. Horizontally polarized radiators are designed using a novel non-inclined edge wall slots whereas the vertically polarized slots are implemented using broad wall slots opened on baffled single ridge rectangular waveguides. Electromagnetic model based on an infinite array unit cell approach is introduced to characterize the slots used in the array. 20 by 10 element planar array of these slots is manufactured and radiation fields are measured. The measurement results of this array are in very good accordance with the simulation results. The dual polarized antenna possesses a low sidelobe level of -35 dB and is able to scan a sector of ±
35 degrees in elevation. It also has a usable bandwidth of 600 MHz.

Abstract:
Multistatic radar system provides a great number of advantages over monostatic radar systems via exploitation of geometrical diversity which gives the ability to view targets from multiple perspectives. These advantages include target signature enhancement, improved detection, higher immunity against countermeasures and provide more information about targets and hence enhance targets classification. Furthermore, the passive receive-only nodes are more compact, hence lighter weight, and can be mounted on UAV which leads to a great advantage to surveillance systems and military applications. Over the last two decades, University College London and the University of Cape Town have collaborated to develop multistatic radar systems. This collaboration resulted in developing an S-band system (NetRAD). Recently, a new version of the system (NeXtRAD) that operates in X and L bands has been developed. The NeXtRAD system has two channels at X-band which allows for receiving fully polarimetric data from clutter and targets utilising dual-polarised antenna. The first addressed task of this work was to investigate all possible antenna candidates to be used for the NeXtRAD system. Resonant SWGAA was chosen among the antenna options as it fit best all desired criteria and due to its relative design simplicity, high power-handling capabilities and cost-effective fabrication. The SWGAA can be designed to be a dual-polarised antenna. The procedures for designing a low sidelobe level (SLL) S-band SWGAA are demonstrated in this work. The azimuth beamwidth of a SWGAA is controlled by the number of slots carved in a waveguide. Eight slots distributed around the centre-line of waveguide broad wall found to meet the desired beamwidth. Four SWGAAs were designed and fabricated. The anechoic chamber measurements of each SWGAA showed excellent agreement with the simulation results. A single element SWGAA has a fan elevation beamwidth. This beamwidth has to be narrowed to achieve the desired width. Stacking identically designed SWGAAs was found to be an effective and simple method to narrow the antenna elevation beamwidth. The four SWGAAs were stacked on top of each other. The mitigation of mutual coupling between stacked SWGAAs was investigated. A cost-effective method of inserting dielectric sheets between stacked SWGAAs helped in mitigating the mutual coupling and assist in arriving at the desired antenna performance. The stacked SWGAAs shows a very good performance with very low SLL and high polarisation purity (low cross-polarisation level). The stacked SWGAAs antenna performance was validated in field experiments and compared to similar characteristics antenna. The SWGAA shows better performance compared to the other antenna. A new simple and efficient design of a dual-polarised SWGAA by having two similar set of stacked waveguides with one set rotated by 90ᵒ relative to the other one was proposed. Two designs with two different elevation beamwidths were simulated. Both designs showed excellent performance that met all the desired criteria. The same designs and tests procedures were followed in designing and testing the X-band SWGAA and simulating dual-polarised antennas. No field experiments were performed using this antenna as the NeXtRAD system is based at UCT and no access to any other X-band radar system at UCL.

Abstract:
Afin de répondre aux besoins croissants d’équipements de communication pour les applications spatiales, il est important de réduire, le plus possible, la taille et la masse de l’équipement des satellites. Cela conduit à une réduction des coûts de lancement des satellites sur leur orbite ou laisse la possibilité d’ajouter des équipements dans la fusée. Ceci compte aussi pour les composants radioélectriques. L’objectif étant de réduire les dimensions sans pour autant détériorer les performances en rayonnement (directivité, polarisation croisée, bande monomode, etc.). Il est possible de contrôler la propagation des ondes électromagnétiques dans les antennes cornets et les guides d’onde à l’aide de surfaces anisotropes (corrugations, métamatériaux). Ainsi, contrairement à ce que prédisent les lois physiques sur la propagation et le rayonnement d’ondes électromagnétiques dans des structures classiques, les performances des structures à parois anisotropes peuvent être radicalement améliorées : pour le guide d’onde, réduction de la fréquence de coupure ; pour l’antenne cornet, amélioration de la directivité ou réduction du niveau des lobes secondaires. D’après l’état de l’art, même si les résultats de simulations et de mesures obtenus sont très prometteurs, le dimensionnement de la structure des métamatériaux est sujet à optimisation, donc gourmand en ressources informatiques. L’apport principal de cette thèse a été de développer une nouvelle méthodologie de conception s’appuyant sur une Théorie Modale Elargie (TME) analytique pour des guides d’onde à parois anisotropes. Elle permet de dimensionner très rapidement des surfaces à métamatériaux les plus adaptées aux applications requises. Un prototype de guide d’onde et un prototype d’antenne ont été conçus, fabriqués et mesurés grâce à cette méthodologie. Les résultats obtenus démontrent l’intérêt, l'efficacité et le caractère général de la méthode proposée pour la conception de dispositifs hyperfréquences guidés à parois anisotropes.

ENGLISH ABSTRACT: The aim of this thesis is to investigate the suitability of TEM (Transverse Electromagnetic) horn antennas for use as feed structures for the Square Kilometre Array (SKA) radio telescope, in particular with regard to the roundness of the radiation pattern. A literature study shows that existing TEM horn designs do not yield a round radiation pattern over a wide bandwidth and that an alternative is required. The Method of Moments (MoM) is a computational electromagnetic (CEM) technique typically used in the analysis of TEM horn antennas. An in-house MoM solver is successfully developed to analyse such antennas and is able to calculate the current density on the surface of a conductor, as well as the farfield patterns of an antenna. A modification to an exponential TEM horn antenna is proposed and simulations show the modification is successful in yielding a round radiation pattern over a wide bandwidth. The modified exponential TEM horn has a convex triangular arc at the end of each antenna plate and is constructed for measurement. Due to limited construction capabilities, the measurements deviate slightly from the simulated results but still indicate the potential of the structure to yield a round radiation pattern over a wide bandwidth.

Abstract:
Afin de répondre à la demande croissante de nouveaux services, les objets que nous utilisons au quotidien (les smartphones, les voitures, les avions, etc.) tendent à intégrer de plus en plus de systèmes radio tandis que l’espace disponible pour l’intégration de ces éléments est de plus en plus réduit. Ces systèmes radio nécessitent l’utilisation de plusieurs antennes devant répondre à des critères de compacité, d’isolation, de coût, etc. À titre d’illustration, un smartphone contient plusieurs antennes pour assurer des fonctions telles que la téléphonie, la navigation, la connexion à internet par WiFi, les liaisons Bluetooth, la technologie NFC (Near-Field Communications) et ce nombre tend à s’accroitre considérablement avec l’émergence de nouveaux services. Le même phénomène se retrouve également au niveau des plateformes aéroportées où des fonctions telles que la communication, la navigation, le radar, etc. sont utilisées. Cela conduit donc à la nécessité de réduire le nombre d’antennes en regroupant par exemple plusieurs fonctions au sein d’une même et unique antenne. Dans de précédents travaux de recherches, J. Euzière a démontré la possibilité de combiner une fonction radar et une seconde fonction (ici de communication) en utilisant un réseau de 16 monopoles initialement dédié au seul radar, grâce au Time Modulated Array (TMA). De cette façon, les deux fonctions utilisaient la même fréquence et étaient alimentées par une seule source. L’objectif principal de cette thèse est de proposer une solution d’antenne multifonction pour radar et communication encore plus compacte (constituée d’une seule antenne). L’idée est de partir d’une solution antennaire déjà existante et d’y apporter les modifications nécessaires à l’ajout d’une seconde fonction, sans pour autant augmenter la surface de l’antenne ni la complexité du système
In order to respond to the increasingly demand of new services, the objects we use on a daily basis (such as mobile phones, cars, airplanes etc.), tend to integrate more and more radio systems while the space available is limited. These radio systems require the use of many antennas that must meet multiple requirements such as compactness, isolation, costs, etc. A smart-phone, for example, contains several antennas for global navigation satellite system (GNSS), WiFi, TV, FM radio, Bluetooth, near-field communications (NFC) and the number is expected to increase as new systems are added. Another example is in airborne platforms where multiple functions such as communication, navigation, radar, electronic warfare are used. This leads to the need of reducing the number of associated antennas by regrouping several radio functions into a single antenna. However, combining the functionality of several antennas into one shared radiating element while maintaining the functionality of the various radio systems presents a great challenge. During its Ph.D, J. Euzière demonstrated the possibility to combine a radar function and a secondary function from a 16-monopole array originally dedicated to radar operation by using Time Modulated Array (TMA) technique. By this way, the two functions were operating at the same frequency and the system was powered by a single source.The main objective of this thesis is to propose a more compact antenna (a single antenna) dedicated to radar and communication operations instead of using antenna array as J. Euzière did it. The idea is to start from an existing antenna solution and make the necessary modifications to add a second function without adding additional surface and complexity. As we are interested in radar applications, we will choose a directive antenna: a horn antenna. The goal is then to study the possibility to modify the radiation pattern of the horn antenna through controllable elements (slots) and to transmit a direct modulated signal at the antenna level for the communication function. Furthermore, polarization diversity is an attractive way to increase the isolation between two applications. Thus, this aspect will be taken into account in the design of the antenna solution

Abstract:
For mm-waves, two types of low-loss waveguide are analysed, designed and measured. One is the hollow substrate integrated waveguide (HSIW) in which the inner dielectric of a traditional substrate integrated waveguide (SIW) is removed to resemble the propagation characteristics of a standard rectangular waveguide (RWG). The measured attenuation of a WR28-like HSIW is 2 Np/m or 17 dB/m throughout the Ka band. The second is the dielectric insular image guide (DIIG) in which an insular layer is added between the dielectric and the metallic ground to further reduce the conductor loss. The measured attenuation of a Ka band DIIG is 26 dB/m at 35 GHz. Based on the two waveguides, two high-gain antenna arrays operating in the Ka band are designed and measured. One is a 6 x 6 slot antenna array, centrefed by the HSIW. The Taylor-distribution technique is applied in two orthogonal directions to suppress the sidelobe level. The measured gain of this antenna array is 17.1 dBi at the centre frequency of 35.5 GHz. The other is a double-sided 10- element dielectric insular resonator antenna (DIRA) array, end-fed by the DIIG. The Taylor-distribution technique is also applied here to achieve a gain of 15.8 dBi at the centre frequency of 36 GHz. The great potential of these high-performance antennas is that they can be integrated with other microwave components (filters, power amplifiers, etc.) to form a complete front-end or transceiver in multi-chip module (MCM) technology.

Abstract:
Slotted waveguide array (SWGA) antennas find application in systems which require planarity, low profile, high power handling capabilities such as radars. In this thesis, a planar, low sidelobe, phased array antenna, capable of electronically beam scanning in E-plane is designed, manufactured and measured. In the design, slot characterization is done with HFSS and by measurements, and mutual coupling between slots are calculated analytically. A MATLAB code is developed for the synthesis of the SWGA antenna. Grating lobe problem in the scanning array, which is caused by the slot positions, is solved using baffles on the array. A high power feeding section for the planar array, having an amplitude tapering to get low sidelobes is also designed using a corrugated E-plane sectoral horn. The power divider is designed analytically, and simulated and optimized with HFSS.

Abstract:
We have demonstrated a waveguide-fed, W-band horn antenna using a three-dimensional (3D), polymeric micro hot embossing process. Two cavity resonators were designed to reduce the impedance mismatch between the horn antenna and the feeding waveguide at a 90° bend. High Frequency Structure Simulator (HFSS) was used to simulate for the performance of the waveguide-fed horn antenna. The antenna directivity and return loss at 95GHz were simulated at 16.56dB and 14.5dB respectively. The measured performance shows impedance match better than 10dB between 76.5~101.7 GHz and 17.5dB at 95GHz. The 3dB beamwidths of the E- and H-plane patterns are 26° and 23° respectively and the total directivity is 17.33dB. The cross-polarized component in the E- or H-planes was 20dB lower than the peak of the corresponding co-polarized component indicating the antenna robustness in rejecting signals with undesired polirization. This plastic, low-cost manufacturing process opens up opportunities in replacing the expensive metallic components with integrated 3D polymeric manufacturing for current and future millimeter-wave systems.
