Abstract:

A holographic function screen (HFS) can recompose the wavefront and re-modulate the light-field distribution from a three-dimensional (3D) light field display (LFD) system. However, the spread function of existing HFSs does not particularly suit integral imaging (II) 3D LFD systems, which causes crosstalk and reduces the sharpness of reconstructed 3D images. An optimized holographic function screen with a flat-top rectangular spread function (FRSF) was designed for an II 3D LFD system. A simulation was carried out through ray tracing, which verified that the proposed diffusion function could suppress crosstalk and improve the overall effect.

Abstract:

This project centers around the design and simulation of a high-gain ultrawideband (UWB) multiple-input multiple- output (MIMO) antenna using Ansys HFSS. The Proposed antenna operates within the UWB frequency range of 3.1 GHZ to 10.6 GHZ, boasting a compact design, high gain, and minimal coupling between its components. The design process in HFSS entails fine-tuning essential factors such as element spacing, feed configuration, and substrate selection to attain a broad impedance bandwidth, high diversity gain, and stable radiation patterns. In Ansys HFSS simulation, the use of full-wave 3d electromagnetic modelling guarantees accurate evaluation of both near-field and far-field parameters. The antenna's performance is assessed based on gain, directivity, VSWR, and return loss. The stability of the radiation pattern across the UWB spectrum guarantees consistent omnidirectional or directional performance, which is crucial for mobile and dynamic communication environments. The findings confirm the effectiveness of the proposed antenna for high-speed data communication systems, such as 5g, IOT, and UWB radar applications. Its compact size, high efficiency, and consistent radiation patterns make it a suitable choice for portable and space-limited devices. The HFSS based approach guarantees precise performance estimation, enabling the creation of cutting- edge UWB MIMO antennas for future communication systems. This thorough approach positions the proposed UWB MIMO antenna as a promising candidate for implementation in emerging technologies like autonomous vehicles, smart healthcare, industrial IOT, and beyond-5g systems.

Abstract:

Hewlett-Packard develops and markets a family of computer-aided engineering products used by high-frequency designers to model the signal path in contemporary communications systems. As design frequencies, clock speeds and packaging densities continue to increase, more designers are finding that system and circuit simulation products need to be complemented by electromagnetic simulation software to develop models for basic circuit functionality or to characterize and compensate undesired parasitic effects. The HP High-Frequency Structure Simulator (HP HFSS) is a frequency-domain, finite element-based simulator, which enables engineers to characterize high-frequency behavior in 2D (transmission lines) and arbitrary 3D structures. Links with mechanical computer aided design (CAD) software have also become more important as the 3D structures to be analyzed by HP HFSS can involve packaging parasitics when the housing in which the electrical circuitry is enclosed becomes an influence on the signal path. Depending upon the complexity of the structure to be analyzed, HP HFSS can require hundreds of Mbytes of RAM and disk during automated adaptive solution convergence processes which determine field and circuit parameter solution results to user-specified accuracies. Although computer resource requirements will always be an important consideration for users of this type of product, another important situation to address for the future involves the exchange of data between the different simulation and modelling tools required to take design from concept through simulation to manufacture. The introduction of physical simulation tools into the traditional circuit simulation arena changes the design process flow and increases the demand for improved integration and interoperability of circuit simulators, numerical EM simulators, and mechanical CAD software. This paper provides an overview of data exchange issues in high-frequency electrical–physical–mechanical design processes.

Abstract:

A magnetic resonance wireless power transfer system based on flexible 3D dual-coil is proposed and implemented in this paper. Firstly, a magnetic coupling resonant circuit model based on dual-coil is established, and the analysis indicates that enlarging the coil inductance and quality factor can effectively improve the transfer efficiency and performance. The coil parametric model is created by HFSS (High Frequency Structure Simulator), the effects of structural parameters on the coil inductance and quality factor are analyzed, and the optimized coil structure parameters are determined. To achieve maximum power transfer, the coupled resonant model after impedance matching is established and simulated in HFSS, and S11 reaches −30 dB at 13.56 MHz. Considering the radiation on human tissues, the SAR (Special Absorption Rate) value is evaluated simultaneously. To confirm the validity of the proposed prototype, the efficient wireless power transfer system composed of two flexible and biocompatible coils with 10 mm radius has been verified by the experimental measurements, and measure results show that the output power is 70 mW, when the transfer distance is 6 mm, the input power is 200 mW, and the maximum transfer efficiency is 35%.

Abstract:

A four-band microstrip patch antenna is designed to work for satellite applications. Out of four bands, one of the bands has a wide band width up to 8 GHz. These microstrip patch antennas can work in the allocated range of 10–40 GHz. The antenna designed can have low return losses and positive gain, which indicates that it can work for practical applications. The designed antenna added stubs on all three corner sides of the microstrip patch antenna for impedance matching. The design used for VSAT applications is the ANSYS HFSS R21. The HFSS (high-frequency structure simulator) software used for analysis of beamwidth, return losses, voltage standing wave ratio (VSWR), gain, gain polar plot, and 3D gain plot has been evaluated and is going to be verified. The gain of the antenna is very high, up to 8.25 dB when compared to the previous design, which was 3.25 dB higher.

Abstract:

A woodpile Electromagnetic Bandgap (EBG) material has been designed, by using an in-house code that implements the Fourier Modal Method (FMM). A couple of alumina-woodpile samples have been fabricated. Several results have been collected for the transmission behaviour of the woodpile and of resonators with woodpile mirrors, in a shielded anechoic chamber, by using a vector network analyzer, in the 8–12 GHz range. These new experimental data highlight interesting properties of 3D EBG resonators and suggest possible innovative applications. Comparisons of the collected results with FMM show a satisfactory agreement. An application of the EBG resonator has been considered, for gain enhancement of a microstrip antenna: an increase of about 10 dB in the broadside gain has been measured; experimental data and numerical results obtained with the commercial software HFSS show a good agreement. A comparison is presented between EBG resonator antennas and two-dimensional uniform arrays. Finally, HFSS results are provided for EBG resonator antennas working at higher frequencies or with a more selective superstrate: a gain enhancement of more than 18 dB is achieved by such antennas.

Abstract:

This report details the design and analysis of a W-shaped meander line antenna utilizing ANSYS HFSS (High-Frequency Structure Simulator). The antenna is distinguished by its compact design, wide bandwidth, and efficient performance for wireless communication applications. Simulation results, including gain, return loss, efficiency, and directivity, confirm the effectiveness of the W-shaped structure in achieving the desired frequency response. The W-shaped antenna employs a meander line pattern resembling the letter 'W,' which contributes to a reduction in the antenna’s physical size while maintaining the necessary electrical properties. The simulation of this antenna was conducted in ANSYS HFSS v2021. Key results obtained include return loss, radiation pattern, 3D polar plot, sidelobe level, beamwidth, radiated power, and accepted power. This meander line W-shaped antenna is designed for a frequency of 5.2 GHz, demonstrating a return loss of less than -10 dB and a bandwidth of 2 GHz. The antenna achieves a gain of 10 dB at perpendicular angles. A significant advantage of this antenna is its capability to provide a wider bandwidth and a radiation efficiency of 98%.

Abstract:

High power (&gt; 30 dBm) RF components such as switches, passives and RF MEMS can be embedded in an advanced 3D package in laminates. We report a novel transmission line and interconnection design for these embedded high power devices. Typical RF signal path consists of input signal lines (microstrip sand coplanar waveguides), interconnections between laminate layers, and RF devices. 3D configurations of multiple buried via holes are first simulated in the HFSS environment and then tested on laminate prototypes for optimized RF performance. Loss points are carefully identified and removed in the design by distributing RF current in a network of interconnections. Extra cooling considerations are included to significantly reduce thermal stress on the system as well as individual components. The final transmission line design can supply over 50 W of RF power into a 12 layer laminate system.

Abstract:

The antenna is designed as a 3D structure and is made from a conductible cylindrical antenna cone. The cone structure is realized using etching of elliptical slot array on the antenna. We use a conductible circular reflector under the proposed cone and increase the gain of the antenna. The proposed antenna provides effective bandwidth from 1GHz to 30GHz, but the gain of the proposed antenna is varying between 3dBi and 15dBi in the frequency band we are interested in. Geometrical details of the antenna are optimized numerically using parametric study using CST MWS Software Package. Once the optimal design is arrived at, the results are validated with another software package using HFSS Simulation Technology. The obtained results from both software packages agree very well.

Abstract:

Interest of Micro-Electromechanical System (MEMS) antennas in Terahertz (THz) applications has rapidly expanded in recent years due to the advent of accurate Computer Aided Design (CAD) tools. The very special needs of newly proposed MEMS antennas, especially with a wide bandwidth range, require advanced optimization procedures of enhancing already established designs. This paper provides a compact design of a wideband MEMS helix antenna optimized using tree-dimensional High Frequency Structure Simulator (3D-HFSS) based on Quasi-Newton (Q-N) and Sequential Non Linear Programming (SNLP) techniques to modify the antenna structure with a high accuracy for the selective band of frequencies by training the samples and minimizing the error from Finite Element Method- (FEM) based simulation tool. The helix antenna is presented using MEMS technology and shows high performance demonstrated by very low return losses of less than -20 to -65 dB for a wide range of frequencies from 2.5 to 5 THz. High antenna geometry precision and efficient performance are finally achieved by rectifying and synthesizing various tunable parameters embedded in silicon substrate including both helix form and feeding line parameters.

Abstract:

An elliptic band pass response three-dimensional Frequency Selective Surface (3D FSS) is designed from a single unit cell of 2D array of two shielded microstrip lines. The designed FSS provides pseudo-elliptic band-pass frequency response (5.4 – 9.6) GHz with its application in long-distance radio telecommunications and space communications etc. The four transmission zeros at 5.4GHz, 9.6GHz, 12.4GHz and 15GHz provides wide out-of-band frequency rejection. The 3D FSS is independent of the variations in the incident angle of the plane wave up to 60 degree. Each unit cell is a combination of two shielded microstrip lines with one having an air gap and the other one having in between rectangular metallic plate. When a TE polarized plane wave incidents perpendicular to the perfect electric conductor (PEC) boundary walls shielded microstrip lines, it results in two quasi-TEM modes namely air and substrate mode. The 3D FSS consists of multiple resonators with a multimode cavity having number of propagating modes. These resonating modes in phase provide transmission poles and when out of phase give transmission zeros. The 3D FSS structure is simulated using Ansys HFSS software with improved performance over 2DFSS, for many practical applications such as antenna sub-reflector, radomes and spatial filters.

Abstract:

Microwave imaging utilizes low-power near-field electromagnetic fields at microwave frequencies to detect the internal structure of an object. Sufficient resolution through the thickness is crucial in biomedical applications to detect small objects of concern. Parameters such as the frequency of microwave signals, the design, and the material of the antenna are the most important factors to consider for microwave-based biomedical sensing. The proposed antenna yields merits of: compactness in size, ease of fabrication, wider impedance bandwidth, simple design, and good RF performance. An Asymmetric-fed Coupled Stripline (ACS) antenna is 3D-printed on an FR4 substrate with return loss measurements ranging from 2 GHz to 20 GHz. The impedance bandwidth is obtained between 6 GHz to 8 GHz and 15 GHz to 17 GHz. The proposed microwave antenna was simulated using Ansys HFSS. The parameters are designed to ensure optimum radiation efficiency. The radiation patterns obtained were omnidirectional in H-plane and bidirectional in E-plane.

Abstract:

This study investigates a meta-atom exhibiting a broad Negative Refractive Index (NRI). The meta-atom is constructed using a complementary circular-square split-ring resonator shaped in an inverse C design. The electromagnetic properties of the structure were analyzed through simulations using CST Microwave Studio, Ansys HFSS 3D software, and ADS. The meta-atom demonstrates three distinct resonant frequencies at 2.71 GHz, 4.19 GHz, and 5.60 GHz, spanning both the S- and C-bands. Its optimal Effective Medium Ratio (EMR) is 12.30, and the unit cell measures 9 mm × 9 mm with a substrate thickness of 0.508 mm. This design is notable for its compact dimensions, strong NRI performance, high EMR, and well-defined resonance points. The S-band, commonly used for radar, and the C-band, which supports high-speed Wi-Fi networks, are both covered by this structure. The paper outlines the design methodology and various parameter optimization processes. Simulation results from Ansys HFSS align well with those from CST and ADS. Additionally, the study includes an analysis of surface current distributions, as well as the electric (E-field) and magnetic (H-field) field patterns. Compared to alternative designs discussed in the article, this proposed structure offers superior performance, showcasing a high EMR, extensive NRI range, and a compact form factor suitable for radar and Wi-Fi applications.

This paper presents the implementation of virtual and real experiments in three math-heavy engineering courses at the University of Southern Maine. These courses were Communications Engineering, Antennas, and Plasma Engineering. Furthermore, the virtual experiments implemented were MATLAB R2022b simulations, HFSS simulations, and videos. The real experimentation included antenna building, a software-defined radio project, a 3D printing project, and a case study analysis. These virtual and real experiments were distributed between the aforementioned three courses. Based on student feedback, having these virtual and real experiments aided their learning process and students enjoyed having hardware experiments embedded in a course.

The filter is mainly composed of eight pairs of series LC resonators, which generate passbands and transmission zeros. Considering the requirement of miniaturization and low cost, the filter is realized by interdigital capacitors and microstrip section inductors. The layout is designed by 3D simulation software HFSS, and the active part is designed by ADS software. The proposed filter has a compact structure, and its size is only 22.20 mm × 25.66 m m.

Abstract:

Microwave ovens have become an essential cooking appliance owing to their convenience and efficiency. However, microwave ovens suffer from uneven distribution of energy, which causes prolonged delays, unpleasant cooking experiences, and even safety concerns. Despite significant research efforts, current solutions remain inadequate. In this paper, we first conduct measurement studies to understand the energy distribution for 10 microwave ovens and show their energy distribution in both 2D and 3D is very skewed, with notably lower energy levels at the center of the microwave cavity, where food is commonly placed. To tackle this challenge, we propose a novel methodology to enhance the performance of microwave ovens. Our approach begins with the development of a measurement driven model of a microwave oven. We construct a detailed 3D model in the High Frequency Structure Simulator (HFSS) and use real temperature measurements from a microwave to derive critical parameters relevant to the appliance's functionality (e.g., operating frequency, waveguide specifications). We then develop a novel approach that optimizes the design and placement of a low-cost passive metasurface for a given heating objective. Using extensive experiments, we demonstrate the efficacy of our approach across diverse food, optimization objectives, and microwave ovens.

Abstract:

In this study, various Rectangular Microstrip Antenna (RMA) designs operating at 28 GHz frequency for 5G-communication system are performed. All designs are generated and analyzed using a 3D electromagnetic simulation program, ANSYS HFSS (High-Frequency Structure Simulator). Single and array type RMA designs are constructed by using non-contact inset-fed feeding technique. Subsequently, the bandwidth of RMAs is increased by slotting on the ground surface, and adding a parasitic element to the antenna structure. Because of these analyses, for single type RMA, the bandwidth increases from 2.09 GHz to 3.45 GHz. Moreover, for 1 × 2 and 1 × 4 array type RMAs, very wide bandwidths of 7.53 GHz and 4.53 GHz, respectively, are obtained by applying bandwidth enhancement techniques. The success of the study has been demonstrated by comparing outputs of the designs with the some similar, experimental or simulation studies published in the literature.

Examining and evaluating the improved microstrip patch antenna to enhance the performance by the initial objectives are the main contribution of this paper. To achieve multiband operation, the patch's shape is first adjusted later microstrip patch with the slot presented. With the help of the Ansoft HFSS antenna simulator, functional analysis has been shown to examine the impact on antenna resonant frequency. A probe-driven microstrip patch antenna imprinted on FR4 epoxy substrate with 1.6mm thickness and a dielectric constant of 4.4 is developed in this work via the HFSS tool for wireless applications operating between 2 to 5GHz. To achieve multiband operation, the structure of the patch is varied. The impacts on antenna resonant frequency are examined through numerical simulations. The length, as well as the width of a traditional patch antenna, is initially computed, and further, an appropriate patch dimension of 28.3mm x 36.9mm has been determined. For multiband operation over the frequency ranging between 2 and 5GHz wireless applications, a probe-driven microstrip patch antenna imprinted on FR4 epoxy substrate with 1.6mm thickness and a dielectric constant of 4.4 is built via the HFSS tool. The proposed architecture of a traditional microstrip patch antenna is imprinted on an FR4 epoxy substrate with a 1.6mm thickness and a 4.4 dielectric constant. The proposed antenna design is illustrated for the 3D structure of the Mutual Coupling Steered Array-Lens Antenna System (MPA) with an improved patch. To achieve multiband operation, two slots are inserted on the edges of the patch, and both the slots are 2mm wide, as well as the depth of the slots is modified to see how it corresponds to the resonant frequency. This work is mainly concentrated on (i) Examining as well as evaluating the improved microstrip patch antenna to enhance its performance, (ii) Examining, evaluating, as well as assessing the performance of an improved split ring resonator metamaterial, and (iii) Exploring, analyzing, as well as evaluating the performance of dielectric lens base patch array antennas and (iv) Developing as well as analyzing the transmission line phase shifter. The groundwork for developing this work is being carried out, and a comparative study is made on (i) techniques for improving the antenna's performance through the application of a modified patch antenna, a Modified split ring resonator, a Dielectric lens structure, and Transmission line phase shifter.

В статье рассматривается оптимизированная методика расчёта параболических антенн с рупорным облучателем для использования в системах спутниковой связи в свете современных тенденций к подключению базовых станций стандарта 5G к спутниковым каналам передачи. Суть методики оптимизации расчёта рупора заключается в преобразовании формул для вычисления пирамидальных рупоров. Вычисление параболического зеркала осуществляется с минимальными необходимыми параметрами. Для оценки оптимизированного расчёта производится построение в программном продукте для электродинамического 3D-моделирования HFSS. В ходе моделирования создаются фигуры с нулевой толщиной и идеальным проводником в качестве покрытия (PEC). Вокруг моделей рупора и зеркала создаются две расчётные области, включенные в один домен. Результаты вычисления выводятся в виде двумерных и трехмерных диаграмм, а также в декартовой системе и отображают коэффициент усиления, выраженный в дБ, и напряженность поля, выраженную в дБм. Полученные результаты свидетельствуют об успешной оптимизации методики расчёта так как, максимально приближены к реальным измерениям. Полученная методика расчёта, а также принципы моделирования параболических антенн с рупорным облучателем в CAD-системах могут быть использованы в учебном процессе при изучении антенно-фидерных устройств.

Abstract:

We present a systematic approach for producing microstrip antennas using the state-of-the-art-inkjet printing technique. An initial antenna design based on the conventional square patch geometry is adopted as a benchmark to characterize the entire approach; the procedure then could be generalized to different antenna geometries and feeding techniques. For validation purposes, the antenna is designed and simulated using two different 3D full-wave electromagnetic simulation tools: Ansoft’s High Frequency Structure Simulator (HFSS), which is based on the Finite Element Method (FEM), and CST Microwave Studio, which is based on the Finite Integration Technique (FIT). The systematic approach for the fabrication process includes the optimal number of printed layers, curing temperature, and curing time. These essential parameters need to be optimized to achieve the highest electrical conductivity, trace continuity, and structural robustness. The antenna is fabricated using Inkjet Printing Technology (IJPT) utilizing Sliver Nanoparticles (SNPs) conductive ink printed by DMP-2800 Dimatix FujiFilm materials printer.

Abstract:

Radio frequency identification is being overloaded with data information, making wideband band antennas very appealing. In this paper, we present a new design of dual band antenna for RFID reader applications operating at 2.45Gz and 5.8GHz with an average gain of 1.16dB at the lower frequency band and 3.2dB at the higher frequency band. The antenna is designed on an FR-4 substrate having a relative dielectric constant of 4.4 and loss tangent of 0.025. The proposed antenna is simulated, designed and, optimized using CST Microwave Studio and has a small size of 32 mm x 26 mm x 1.6 mm. The antenna consists of a steeped rectangular patch antenna using a partial ground plane loaded a modified split ring resonator. The metamaterial structure was designed and optimized to operate at 2.45GHz and its effective parameters was verified using the Nicolson-Ross Weir method. The performance of the proposed antenna is confirmed by another 3D electromagnetic solver HFSS.
