Abstract:
A multiband rhombus-shaped patch antenna with rhombus slots is presented in this paper. The dimensions of the proposed antenna are 50x48x1.2mm 3 at the operating frequency is 5.54GHz. The rhombus patch antenna with rhombus slots results in a multiband operation operating in a bandwidth of 80MHz (6.60GHz to 6.68GHz), 80MHz (8.36GHz to 8.44GHz), 400MHz (12.65GHz to 13.05GHz), 450MHz (14.76GHz to 15.21GHz), and 990MHz (16.73GHz to 17.72GHz) with a peak gain of 6.02dBi at 12.88GHz and exhibits circular polarization at the frequency range of 15.56GHz to 15.77GHz. The proposed antenna is suitable for C, X, and Ku-band applications. Simulations are carried out using Ansys HFSS software.Keywords:

This paper studies the effect of dielectric covers or superstrate with different thickness on rectangular microstrip patch antenna. The proposed antenna is designed at 2.4GHzfrequency using method of transmission line model. The dielectric covers or superstrates are providing protection to the antenna from different environmental hazards conditions. The HFSS electromagnetic simulation software is used for simulating the antenna using different dielectric superstrate covers. The different cover thickness affects is investigated on microstrip antenna and compared their performance with and without superstrates.

This paper presents a Bandwidth enhancement of Rectangular microstrip patch antenna (RMPA) using defected ground structure (DGS). A simple RMPA is designed which works at 2.4 GHz frequency. This antenna is considered as reference antenna. This antenna has bandwidth of 67 MHz. In this RMPA DGS technique is integrated. U shape DGS is inserted in a simple RMPA. Due to DGS, Bandwidth is improved compared to earlier antenna. Later this U shape DGS is modified to E shape DGS. Later this E shape DGS is modified to Double E shape DGS and finally into Psi shape DGS. The bandwidth of simple RMPA was 67 MHz which got improved to 302 MHz at 2.4 GHz frequency of with Psi shape DGS. The bandwidth received is suitable for different applications of WLAN. Ansoft HFSS software is used for simulation of the designed structure.

In this study, a new microstrip patch geometry, called Seljuk star, is proposed. The performance of the designed antenna is compared with the performances of square and circular microstrip antennas, which are two other popular patch geometries in literature. The design procedure consists of two phases: First, the patch dimensions of circular and square antennas are taken as the same with Seljuk star dimension. Then the patch surface areas of antennas are fixed to the area of Seljuk star patch and patch dimensions are calculated for the new designs. The effect of different patch types on bandwidth are investigated. Rogers Duroid 6010 ( h = 3.175 mm, ɛ r =10.2) is chosen as the substrate of the antennas which are expected to have a bandwidth center at 5800 MHz. All antenna designs are simulated in HFSS. Each individual antenna is intended to be working at a single frequency, but during the simulations multiple resonance are obtained in many designs. Therefore, the bandwidth and frequency comparisons are done for each resonant frequency among themselves. In comparison to the circular patch geometry with the same surface area, bandwidth is improved 10.57 times, as a result. The deviation between the theoretical calculations and simulations is % 1.38 , which is the smallest deviation among all results. Based on this, it is observed that Seljuk star microstrip patch antenna has a better performance when its dimension or surface area is chosen as same with circular or square antennas. The proposed Seljuk star patch shape is believed to have a high potential to be used in future research.

A miniature WLAN frequency notched printed microstrip antenna with inverted T shaped DGS having a frequency response from 4.66 GHz to 10.99 GHz is suggested in this paper. The general size of the antenna is 19mm× 12mm × 1.6mm simulated using HFSS. The suggested antenna comprises of rectangular patch of size 13.5mm × 8mm as a front view with microstrip feed of size 5mm × 2.8mm. On the rear side we have Defected Ground Structure (DGS) of inverted T shape. The execution of the recommended antenna is investigated by utilizing HFSS.

An optically controlled frequency reconfigurable microstrip patch antenna is presented in this paper. S11 measurements show that greater than 85% power is transmitted at each of the three resonant frequencies. Measured radiation patterns for patch antennas using ideal switch states agree with HFSS simulations.

In this paper, different design of terahertz microstrip array rectangular patch antenna in the range of 0.5-1 terahertz is simulated. Multilayer technique to descend notch depth are applied. We used from Tetraflouroethilen (e=2.08) in homogeneous substrate and we combined it with another material with e=3.82 in two layer substrate as host material. To validate results which came from Ansoft HFSS commercial which are based on finite element method we used analytical method in operating frequency (600GHz). Least square genetic algorithm helped us to optimize geometrical parameters of array such as microstrip feed line and rectangular patch aspects.

The patch shape of microstrip patch antenna is the important factor which affects the performance of antenna.The rectangular microstrip patch antenna and the circular one are designed and simulated with HFSS.Comparison has been made between the two different patch antennas,such as the size,S-parameters chart,pattern and input impendance chart.The simulation result shows that the bandwidth of two microstrip patch antenna is too narrow.By comprehensive consideration of each performance index,the rectangular microchip antenna is better than the circular one.
