Abstract:
The following is an abstract of the paper, the mirror image design parameters and effective results for an antenna with a rectangular microstrip overlay using IE3D software is described that outcomes of the simulations and designs are displayed. The probe feed approach was used to generate the microstrip patch pattern. Such patch antennas have been investigated due to their large bandwidth and gain. This antenna is fabricated on an FR-4 epoxy substrate. This antenna’s performance and results are also matched to a standard rectangular patch antenna. Variables are utilized to improve the antenna’s simulation results are as position, space, length, and width of different mirror images T and I shaped antenna slots. The measured results from the simulated design show that the designed construction resonates at various closely separated frequencies that are within the frequency band allotment for wireless applications. At resonance frequencies of 2GHz to 3GHz, the bandwidth and return loss are significantly enhanced.

Abstract:
The paper discusses the existing design of mirror antennas used on spacecraft. The requirements are formulated under which the reliable performance of antennas is ensured under operating conditions. Innovative construction of the space high frequency axisymmetric mirror antenna of an ultralight class is presented. Antenna’s body consists of several conjugate carbon fiber shells. Antenna’s design technology which gives an opportunity to create the shell of a reflector with minimal deflection from a full-paraboloid is developed. Using the finite element method, a parametric modal analysis of the antenna is performed. Based on this analysis, geometric parameters were determined that provide optimal mechanical and mass characteristics of the structure. The calculation results were used to create a prototype mirror antenna. It is shown that the created antenna possesses the parameters required for generation of the high-directional electromagnetic emission of Q and V frequency domain. Successful ground experimental perfection of the construction of the antenna is made. It included the stages of mechanical, thermal vacuum, and radio engineering tests. The proposed design can be used to create advanced spacecraft.

Abstract:
Some results on embedded antennas for medical wireless communication systems are presented. Medical telemetry can advantageously assist medical diagnostics. For example, you can better locate a diseased area by monitoring temperature inside the human body. In order to establish efficient wireless links in such an environment, a special attention should be paid to the antenna design. It is required to be of a low profile, very small regardless of the working frequency—434 MHz in the ISM band, safe, and cost effective. Design of the as-considered antenna is proposed based on a simple model. The approach has been demonstrated for a compact flexible antenna with a factor of 10 with respect to the half-wave antenna, rolling up inside an ingestible pill. Measured and calculated impedance behaviour and radiation characteristics of the modified patch are determined. Excellent agreement was found between experiment and theory.

Abstract:
A 60 GHz compact and novel shaped microstrip-fed antenna based on a textile substrate for body-centric communications has been proposed in this paper. The antenna has a partial ground, and the textile substrate is made up of 1.5 mm thick 100% polyester. Two rectangular sections from the patch antenna’s radiator were removed to give the antenna a swan-shaped appearance. The antenna was designed and simulated using computer simulation technology (CST) microwave studio software. Simulated results show that, in free-space, the antenna achieved a high bandwidth of 11.6 GHz with a center frequency of 60.01 GHz. With 89.4% radiation efficiency, the maximum gain of the antenna was 8.535 dBi. For the on-body scenario, the antenna was simulated over five different distances from a human torso phantom. At the closest distance from the phantom, the antenna’s gain was 5.27 dBi, while the radiation dropped significantly to 63%. The highest bandwidth of 12.27 GHz was attained at 8 mm, while the lowest bandwidth of 5.012 GHz was attained at 4 mm away from the phantom. Gain and radiation efficiency were comparable to free-space results at the furthest distance. The antenna was also simulated with ten different textile substrates for both free-space and on-body scenarios. Among these ten substrates, denim, tween, and Quartzel fabric had similar performance results as polyester. This design achieved similar performance compared to other 60 GHz textile antennas while being a bit more compact. This antenna will be a promising choice for body-centric communications because of its compact size, textile-based substrate, and excellent on-body performance.

Abstract:
In this study, the absorbing boundary condition is modelled and analyzed by particle swarm optimization for antenna designs. Two pieces of circular and rectangular microstrip patch antennas are designed for results by means of High Frequency Structure Simulator (HFSS) simulation program. These antennas are implemented by printed circuit board technologies. The results of measurements and simulation performed for the antenna determined the optimal absorbing boundary distance. . In order to be closer with simulation and measurement results, data set is generated by varying in absorbing boundary size. Average square error between simulation and measurement data is necessary to be optimized as an objective function. For this reason, optimization algorithm based on swarm intelligence is preferred to be minimized the error function. Thanks to the results of measurements and simulation performed with the antenna, optimal absorbing boundary distance is determined by Particle Swarm Optimization.

Full text
Abstract:
This thesis presents a new approach to the hardware test environment for a twist reflector monopulse antenna system with a radome extending current measurement practice. New research is presented on the optimisation of the design of a twist reflector monopulse antenna system with a radome, significantly improving the design and the design process. A unique extension to current measurement practice, for single channel antennas, is presented to determine the best practice method on phase stable measurements of a multi-channel antenna on a moving positioner. A novel axis transform for a 3 axis positioner system located within an anechoic chamber is derived. It allows for true performance measurement of a twist reflector antenna with a radome. This progresses the field of antenna measurement as, uniquely, this axis transform allows the aberration caused by the antenna radome to be measured and included. Design improvements have been made on polarisation selective grids, the matched thickness of the radome and a new software method that removes the need for a comparator and increases the robustness of the antenna system. Polarisation selective grids, constructed from a set of parallel conductors, have a wide range of uses in antenna systems. This thesis shows that the depth of a copper grid line can be reduced to 15 m and still provide better than -25 dB cross-polar isolation. This is contrary to current understanding at 30 times the skin depth. A new combined approach to radome thickness optimisation is presented that reduces the time taken to calculate the optimal thickness by over 3 orders of magnitude and the computer memory by over 2 orders of magnitude without compromising accuracy. The use of a digital comparator is described and leads to a novel method to compensate for a failed feed element, verifified in both simulation and anechoic chamber measurements.

Abstract:
Small antennas have attracted significant attention due to their prolific use in consumer electronics. Such antennas are highly desirable in the healthcare industry for imaging and implants. However, most small antennas are not highly directive and are detuned when in the presence of a dielectric. The human body can be compared to a series of lossy dielectric media. A novel antenna design, the orthogonal coil, is proposed to counter both of these shortcomings. As loop antennas radiate primarily in the magnetic field, their far field pattern is less influenced by nearby lossy dielectrics. By exciting two orthogonal coil antennas in quadrature, their beams in the H-plane constructively add in one direction and cancel in the other. The result is a small, yet directive antenna, when placed near a dielectric interface. In addition to present a review of the current literature relating to small antennas and dipoles near lossy interfaces, the far field of the orthogonal coil antenna is derived. The directivity is then plotted for various conditions to observe the effect of changing dielectric constants, separation from the interface, etc. Numeric simulations were performed using both Finite Difference Time Domain (FDTD) in MATLAB and Finite Element Method (FEM) in Ansys HFSS using a anatomically accurate high-fidelity head mesh that was generated from the Visible Human Project® data. The following problem has been addressed: find the best radio-frequency path through the brain for a given receiver position - on the top of the sinus cavity. Two parameters: transmitter position and radiating frequency should be optimized simultaneously such that (i) the propagation path through the brain is the longest; and (ii) the received power is maximized. To solve this problem, we have performed a systematic and comprehensive study of the electromagnetic fields excited in the head by the aforementioned orthogonal dipoles. Similar analyses were performed using pulses to detect Alzheimer’s disease, and on the femur to detect osteoporosis.

Abstract:
A linearly-polarized aperture coupled patch antenna design is characterized and optimized using HFSS antenna simulation software. This thesis focuses on the aperture coupled patch antenna due to the lack of fabrication and tuning documentation for the design of this antenna and its usefulness in arrays and orthogonally polarized communications. The goal of this thesis is to explore dimension effects on aperture coupled antenna performance, to develop a design and tuning procedure, and to describe performance effects through electromagnetic principles. Antenna parameters examined in this study include the dimensions and locations of the substrates, feed line, ground plane coupling slot, and patch. The operating frequency, input VSWR, percent bandwidth, polarization ratio, and broadside gain are determined for each antenna configuration. The substrate material is changed from RT Duroid (material in nominal HFSS design) to FR4 due to lower cost and availability. The operating frequency is changed from 2.3GHz (specified in nominal HFSS design) to 2.4GHz for wireless communication applications. Required dimensional adjustments when changing substrate materials and operating frequencies for this antenna are non-trivial and the new design procedure is used to tune the antenna. The antenna is fabricated using 59mil thick double and single sided FR4 boards joined together with double sided 45mil thick acrylic tape. The antenna is characterized in an anechoic chamber and experimental results are compared to theoretical predictions. The results show that the new design procedure can be successfully applied to aperture coupled antenna design.

Abstract:
Cylindrically conformal microstrip antennas are investigated. Two different structures, namely proximity coupled and E-shaped microstrip antennas are analyzed and information about the design parameters is obtained by means of parametric study. With these structures, cylindrical arrays, having omnidirectional radiation in the circumferential plane of the cylinder, are designed. Proximity coupled cylindrical arrays operate in the 2.3-2.4 GHz aeronautical telemetry band with approximately 4% bandwidth. On the other hand, more than 30% bandwidth is obtained by E-Shaped cylindrical array antenna structure, which also includes the commercial telemetry band. In order to verify the simulation method, a fabricated antenna in literature is simulated and acceptable agreement with simulation and fabrication results obtained.

Abstract:

Small planar antennas are becoming increasingly popular in personal wireless communication systems since these antennas offer advantages such as small size,light weight, robust construction, ease of integration into mobile handsets, reasonable radiation efficiency and gain. A new small microstrip antenna operating at 880MHz is designed using the Finite difference time domain technique incorporating the perfectly matched-layer formulation. Shorting pins are used to achieve the reduction in size.The size of this patch antenna is approximately four times less than that of the regular half wavelength patch antenna. An antenna array made of the new patch antennas is used ina multiple antenna system to reliably separate different users on the same channel using linearbeam steering techniques with the ultimate goal of increasing the channel capacity.Prototypes of the proposed dual shorted-pin-patch antenna are fabricated and measurements of their return loss compare well with the computational results.

Abstract:
In this study we tried to design a microstrip antenna, to get a suitable radiation pattern for a LEO satellite. Our aim is to get a radiation pattern that has a maximum power which is not in the broadside direction to the antenna surface
instead broadside radiation has a relatively lower power density. Maximum power radiation is desired to be at about 30 &ndash
50 degrees angle beyond the normal to the antenna surface. We desire circularly polarized radiation. We used two concentric antennas
one is a circular patch at the center and the other is an annular ring which is used at the outer region. By using Ansoft Ensemble 8.0 software, we design an antenna which has a resonance frequency at 8.2 GHz. Using the result of the program we design the real antenna. The measurement results are compared with the simulation results.

Abstract:
In satellite applications, a circularly polarized satellite antenna is desirable with a pattern that results in constant received power while the distance between the transmitter and the receiver is changing. The Circular Disk - Annular Ring (CDAR) antenna satisfies these requirements along with other requirements for the satellite antenna. The CDAR antenna is a combination of a Circular Disk and an Annular Ring patch antennas. In this thesis, a circularly polarized CDAR antenna that is fed from a single point is designed at the center frequency of 8.2 GHz. This antenna is investigated and optimized to ease the fabrication process. The design parameters are defined on this report and optimized by using an Electromagnetic Simulation software program. In order to verify the theoretical results, Circular Disk - Annular Ring Antenna is produced as a prototype. Measurements of antenna parameters, electromagnetic field and circuit properties are interpreted to show compliance with theoretical and simulation results. The values of deviation between theoretical and experimental results are also discussed.

Abstract:
For high electromagnetic performances, large space truss antennas should have reflector surface with an extremely high precision. Due to the varied load and some random disturbances, active control strategy is always used in the kind of structure for the precise surface. For the improvement of the electromagnetic performances, an electromechanical synthesis optimization model of space antenna structure systems is developed based on the antenna’s characteristics, which adopts the axial gain of antenna and power consumption of actuators as the objective functions, and structural material strength and actuator’s capability as constraint conditions. The application of model to an 8-m antenna structure demonstrates the potential for significant improvement.

Abstract:
Origami allows for novel approaches to the design of morphing structures. This paper presents a preliminary study on the analysis and design of a self-folding origami antenna. This preliminary study aims to develop and test novel origami analysis and design approaches for problems in morphing antennas. A parabolic dish antenna is considered. The objective is to design a planar sheet with a pattern of smooth folds (as opposed to creased folds generally encountered in the origami literature) that can fold via active material actuation towards the parabolic antenna shape. In the presented process, a mesh discretization of the parabolic shape is first determined. Subsequently, an origami design tool previously developed by the authors is utilized to obtain a planar sheet with a pattern of smooth folds that allows for folding towards the meshed parabolic shape. An origami structural analysis method is then used to simulate the shape memory alloy (SMA) actuation-driven folding of the determined sheet design from the planar reference configuration towards the parabolic configuration. The mesh discretization of the parabolic shape is parameterized and various discretizations are tested and compared considering certain performance outputs. The preliminary results presented here demonstrate the feasibility of active material-based origami in the development of morphing antennas.

Abstract:
Balancing stiffness and weight is of substantial importance for antenna structure design. Conventional fold-rib antennas need sufficient weight to meet stiffness requirements. To address this issue, this paper proposes a new type of cable-rib tension deployable antenna that consists of six radial rib deployment mechanisms, numerous tensioned cables, and a mesh reflective surface. The primary innovation of this study is the application of numerous tensioned cables instead of metal materials to enhance the stiffness of the entire antenna while ensuring relatively less weight. Dynamic characteristics were analyzed to optimize the weight and stiffness of the antenna with the finite element model by subspace method. The first six orders of natural frequencies and corresponding vibration modes of the antenna structure are obtained. In addition, the effects of structural parameters on natural frequency are studied, and a method to improve the rigidity of the deployable antenna structure is proposed.

Abstract:
Large deployable membrane antennas for Synthetic Aperture Radar (SAR) satellites have attracted much attention for their low mass, high packaging efficiency, and low fabrication cost. An extendible support structure (ESS) could be used to deploy and support a multi-layer membrane antenna in a precise configuration once it is deployed on orbit. In this paper, an ESS for a membrane antenna with several foldable frames is designed. The ESS can be synchronously deployed by a six-bar-linkage mechanism and several closed-cable loops. A kinematical model of the deployable mechanism is developed to obtain the optimal design of the mechanism for a goal of all foldable frames locked in a same plane after they are fully deployed. A dynamic model of the ESS is developed to investigate its dynamical performance. The goal of the simulation is to compare the dynamic performances of the ESS when the frames are regarded as rigid and flexible. The simulation results are obtained with symbolic dynamic analysis software DynaFlexPro.

Abstract In this paper a model is developed for the 60-foot satellite tracking antenna at Vandenberg Tracking Station (VTS). The model includes the control system, the motors, and the antenna structure. The antenna performance is simulated, using MATRIXX/SystemBuild, for two kinds of inputs: step functions and satellite passes. The predicted antenna performance is then compared to real antenna data, that was recorded at VTS, in order to demonstrate the accuracy of the model. Finally, the model is used to predict the antenna performance on a satellite pass for which no real data is available. The model shows that the antenna is capable of performing this pass with tracking errors less than the specified 2 milliradians (0.114°).

Abstract:
In order to design lightweight and high stiffness large-sized deployable antenna mechanism, a kind of slider crank basic deployable mechanism unit which is driven by elastic hinges and one sort of double-layer loop deployable antennas mechanism which is composed of the units are put forward. In this paper, the method of finite element dynamic models for double-layer loop deployable antenna mechanism and the control variable method are combined to conclude the interaction relationship between the fundamental frequency of double-layer loop deployable antenna with the mechanism geometric parameters of the antenna diameter, height, thickness and other geometrical parameters of the double layer loop antenna. On this basis, an empirical formula of fundamental frequency calculation of double-layer loop deployable antenna mechanism is achieved. According to the performance of the frequency of the antenna mechanism, the antenna diameter is divided into small diameter, large diameter and super large diameter three grades. The influences of the mass and the stiffness of antenna mechanism are taken into comprehensive consideration, then a comprehensive evaluation index of the single-layer and double-layer loop deployable antenna mechanism characteristics is set up to make comparative analysis of the dynamic characteristics of the unfolded single-layer and double-layer deployable antenna mechanism with different diameters. It is concluded that the applicable diameter range of the single-layer loop deployable mechanism is 1m to 20m, while the applicable diameter range of the double-layer loop is 20m to 100m.

Abstract:
Abstract The LQG controllers, designed for the NASA Deep Space Network antennas have small tracking errors and are resistant to wind disturbances. However, during antenna slewing, they induce limit cycling caused by the violation of the antenna rate and acceleration limits. This problem can be avoided by introduction of a command that does not exceed the limits. The command preprocessor presented in this paper generates a command that is equal to the original command if the latter does not exceed the limits, and varies with the maximal (or minimal) allowable rate and acceleration if the limits are met or exceeded. It is comparatively simple since it requires only knowledge of the command at the current and the previous time instants, while other known preprocessors require knowledge of the terminal state and the acquisition time. Thus, the presented preprocessor is more suitable for implementation. In this article analysis of the preprocessor is presented. Also the performances of the preprocessor itself, and of the antenna with the preprocessor is illustrated with typical antenna commands.

Abstract:
Large deployable antennas for space applications become essential in the fields of communications, radio astronomy and Department of Defence (DOD) space-based radar. Since the antenna should be installed in a cargo space of a rocket vehicle during the launch phase, an inflatable deployment concept is inevitable to overcome the size limitation. A newly developed class of space structures, called inflatable-deployable structures, has great potential for satisfying these stringent user requirements. Among the many antenna types available, the parabolic reflector antenna is the most common one mainly due to its high gain, which enable high data rate transmission at low power. Large parabolic reflectors and solar concentrators are of great interest for the applications of satellite. This paper presents the finite element modelling of the parabolic shaped reflector to know the static and dynamic behaviour under the various inflation pressures. Purpose of this study is to highlight the dynamic characteristics of parabolic structures used in space application. The challenge is to assure that inflatable parabolic surfaces have significantly high efficiency and accuracy to satisfy the system requirements. Even the smart material is used for the control of the geometry of the reflecting surfaces and the study is done for the optimal size and placement of actuators and sensors the control of the shape of the reflecting surfaces. So this study is required to understand the dynamic characteristics i.e. frequency and mode shapes of these structures so that we can find out the maximum deflection and deformed shape of the parabolic surfaces.

Abstract:
Use of ferroelectric materials to improve antenna performance is an area of active research. Applying an electric field across a ferroelectric used as the dielectric in an antenna enables tuning the antenna performance. Ferroelectrics also have coupled electromechanical behavior due to which it is sensitive to mechanical strains and fluctuations in ambient temperature. Use of ferroelectrics in antenna structures, especially those subject to mechanical and thermal loads, requires knowledge of the phenomenological relationship between the ferroelectric properties of interest (especially dielectric permittivity) and the external physical variables, viz. electric field(s), mechanical strains and temperature. To this end, a phenomenological model of ferroelectric materials based on the Devonshire thermodynamic theory is presented. This model is then used to obtain a relationship expressing the dependence of the dielectric permittivity on the mechanical strain, applied electric field and ambient temperature. The relationship is compared with published experimental data and other models in literature. Subsequently, a relationship expressing the dependence of antenna performance on those physical quantities is described.
