چکیده
In this paper, microstrip patch antennas with six different shapes i. e. rectangular, circular, square, elliptical, pentagonal and hexagonal are implemented using Ansoft HFSS version 13. 0. 0 software. Antennas are designed on Rogers RT/duroid 5880 material with dielectric constant 2. 2 and thickness 3. 2 mm. The different performance parameters such as return loss, gain and bandwidth of these antennas are compared. The operating frequency for all these antennas is taken 7. 5 GHz. All the antennas are fed with the probe feed. It is found that pentagonal microstrip patch antenna has better results at this frequency than all other shapes.

An accurate model named as the Modified Wolff Model (MWM) is presented as an efficient CAD tool for determination of resonant frequency of the dominant and higher order modes under the multi-layer condition in thin and thick circular microstrip patch antennas. The effects of dielectric cover on the resonant frequency obtained from MWM have been compared against the result of theoretical method ...

متن کاملComplementary Split Ring Resonator Effects on Radiation Pattern Reconfigurable Circular Microstrip Antennas
In this study, a radiation pattern reconfigurable microstrip antenna is designed and fabricated. The antenna’s radiation pattern is directed in 9 different angles by employing a radiating patch and embedding complementary split ring resonators (CSRR) on the ground plane. The radiating patch is of circular shape, while for CSRR elements both circular and rectangular shapes are investigated. The ...
