Abstract:

In this paper we present a coaxial filter analysis software based on MATLAB. Our software can obtain scattering parameters’ curve of the filter which is composed of high-low impedance coaxial cables. In order to obtain scattering parameters’ curve, we introduce a method of making distributed parameters equivalent to lumped parameters and adopt A parameter matrix approach to get it. Our software has taken into account the influence of step capacitances. Compared with the commercial software HFSS, our software has advantages of strong pertinence, operating fast and easy to adjust. Finally, we use HFSS to validate the correctness of our software.

Abstract:

A micro-strip fed slot antenna array for the ISM band was built using standard formulas for calculating various antenna parameters. Half power beamwidth 57°, throughput about 7.7%. This is obtained by matching the impedance and the high level of the surface waves. To expand the bandwidth, a direct-coupled power was used, which provides the largest bandwidth, is fairly easy to model, and has low spurious radiation. A directivity of 2.01 dB was achieved. This is a fairly high figure, although an increase in directivity can also be obtained by using a different material and thickness of the substrate. HFSS software examines and analyzes antenna characteristics, including voltage standing wave ratio, return loss, and far-field radiation patterns.

Abstract:

Abstract In this paper, a micro-strip fed slot antenna array for application in the 2.4GHz industrial, scientific and medical(ISM) band is implemented using the Ansoft HFSS software. Standard formulas are used to calculate different antenna parameters. The proposed antenna is designed to work at 2.4GHz frequency band. A half power beam width(HPBW) of 57°. A bandwidth of around 7.7% is attained. This may have been brought about by poor impedance matching and a high level of surface waves. A way of improving the bandwidth would have been to use proximity coupling feeding method which offers the highest bandwidth and is somewhat easy to model and has low spurious radiation. However, its fabrication would have been more difficult. A directivity of 2.01 dB is achieved. This is a fairly high though directivity increase could have been studied through use of different substrate material and thickness. Adjusting length and width of narrow slot loop antenna will influence on the resonance frequency and bandwidth. By using HFSS software, the characteristics of antenna are investigated and analyzed, including voltage standing wave ratio (VSWR), return loss and far field radiation patterns.

Abstract:

In this paper, we use electromagnetic simulation software HFSS to investigate the distribution of electromagnetic field of microwave sintering cavity, and establish a simulation model for the TE103 single mode cavity. We then obtain the optimal condition for the distribution of electromagnetic field by capturing the contour of distribution of electrical field of cavity through simulation. Our research shows that electromagnetic simulation software HFSS can use color to effectively demonstrate the intensity distribution of electromagnetic field of internal space and various cross-sections within the microwave sintering cavity, which provides a novel method for improving and applying new ways to compute and predict the key features of field distribution. The simulation results by HFSS can guide the practical microwave sintering techniques as well as the design and improvement of the sintering cavity.

Abstract:

In this study, the simulation model of Aperture-Coupled Micro-Strip Antenna (ACMA) by using Artificial Neural Network (ANN) is proposed. The developed model tries to predict the output resonance frequency of the ACMA according to the input physical parameters of the antenna. ACMA models were designed in High Frequency Structure Simulator (HFSS) software tool that could conduct three dimensional full-wave electromagnetic structure analysis based on Finite Element Method. Main objective is to simulate HFSS model via proposed learning model. Levenberg-Marquardt (LM) is utilized as a learning algorithm. 500 different ACMA models was designed in HFSS tool. Physical dimensions and output operating frequencies of the ACMA models were recorded in order to establish the dataset. Prediction performance of the proposed ANN simulation model was evaluated by 5-fold cross-validation scheme. Overall generalization error was calculated as 3.58 %. Experiments revealed that proposed simulation model operates at least ten thousand times faster than HFSS software. Due to its overwhelming running speed, it was concluded that proposed LM-ANN simulation model can be utilized as a preliminary search tool for optimizing the industrial ACMA models.

Abstract:

Frequency selective surface (FSS) is a two-dimensional periodic structure. It exhibits total reflection and transmission in the neighborhood of the element resonances. As it performs as a filter, FSS is widely used in the fields of microwave and optics.

Hexagonal element of frequency selective surface is as an example to explore the simulation method and the process of Ansoft HFSS. Through the comparison of the simulation curves and the measured curves of hexagonal element frequency selective surface film by photoetching technology, the simulation method of Ansoft HFSS software for frequency selective surface is correct. At the same time, this paper further verified the reliability of the simulation through the example of the ring and the cross unit structure.

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:

Thus far, the adoption of hydrogen fuel cell vehicles (HCEVs) has been hampered by the lack of hydrogen fueling infrastructure. This study aimed to determine the optimal location and prioritization of hydrogen fueling stations (HFSs) in Seoul by utilizing a multi-standard decision-making approach and optimization method. HFS candidate sites were evaluated with respect to relevant laws and regulations. Key factors such as safety, economy, convenience, and demand for HCEVs were considered. Data were obtained through a survey of experts in the fields of HCEV and fuel cells, and the Analytic Hierarchy Process method was applied to prioritize candidate sites. The optimal quantity and placement of HFSs was then obtained using optimization software, based on the acceptable travel time from intersections of popular roads in Seoul. Our findings suggest that compliance with legal safety regulations is the most important factor when constructing HFSs. Furthermore, sensitivity analysis revealed that the hydrogen supply cost currently holds the same weight as other elements. The study highlights the importance of utilizing a multi-standard decision-making approach and optimization methods when determining the optimal location and prioritization of HFSs and can help develop a systematic plan for the nationwide construction of HFSs in South Korea.

The accuracy of the simulated surface currents, which are physically related to the impedance at the feeding point of the antenna, depends on the convergence of the electromagnetic fields inside the simulation volume. The introduced method estimates the overall quality of the simulation results by combining the surface currents with the electromagnetic fields extracted from the field solution of Ansoft HFSS.

Full text

Abstract:

In order to determine the membership of an element to a set owing to ambiguity between a few different values, the hesitant fuzzy set (HFS) has been proposed and widely diffused to deal with vagueness and uncertainty involved in the process of multiple criteria group decision making (MCGDM) problems. In this paper, we develop novel definitions of score function and distance measure for HFSs. Some examples are given to illustrate that the proposed definitions are more reasonable than the traditional ones. Furthermore, our study extends the MULTIMOORA (Multiple Objective Optimization on the basis of Ratio Analysis plus Full Multiplicative Form) method with HFSs. The proposed method thus provides the means for multiple criteria decision making (MCDM) regarding uncertain assessments. Utilization of hesitant fuzzy power aggregation operators also enables facilitating the process of MCGDM. A numerical example of software selection demonstrates the possibilities of application of the proposed method.

Abstract:

Abstract: This paper focuses on the design and simulation of a microstrip patch antenna for Wireless Sensor Network (WSN) applications, utilizing HFSS (High-Frequency Structure Simulator) software and an FR-4 epoxy substrate. The objective is to develop an efficient and cost-effective antenna tailored for the 2.4 GHz frequency band, commonly used in WSNs due to its favourable propagation characteristics. The choice of FR-4 epoxy substrate, with a relative dielectric constant (ࡾࢿ (of 4.4 provides a balance of performance, availability, and cost-effectiveness. These properties are crucial in determining the antenna's resonant frequency and overall efficiency. The design process involves optimizing the dimensions of the rectangular microstrip patch antenna to achieve the desired frequency and performance metrics. HFSS simulation tools are employed to model the antenna's behaviour, allowing for precise adjustments and performance predictions. Key parameters analysed include return loss (S11), gain, radiation pattern, and bandwidth.

Abstract:

Ansys platform-based HFSS simulator software is used to create a 4GHz circular micro strip patch antenna array. Applications including Bluetooth, the Internet of Things, and several WLANs can all benefit from it. The circular patch antenna, which is constructed on a FR4 substrate with a dielectric constant of 4.4 and a height of 1.6mm, is fed using edge feeding. The antenna is built using a 1.4mm thick FR-4 (lossy) substrate with a relative permittivity of 4.4 and a microstrip line feed. The chosen radius for the circular patch is 7.62mm. To lower the size and enhance the performance of the suggested antenna, a square slit 30mm by 30mm in size is etched onto the ground plane. The HFSS Simulation Program is employed in the antenna's design. Antenna characteristics such as return loss, radiation pattern, bandwidth, orientation, antenna gain and radiated efficiency are all studied.
