Parametric Performance Analysis of Patch Antennausingebg Substrate

In recent years, microstrip antennas become very popular because of their interesting advantages of low cost, low profile, light weight, easy fabrication and ease of analysis. Electromagnetic Band Gap (EBG) substrate is used as a part of antenna structure to improve the performance of the patch antenna. Usually, the performance of a patch antenna depends on the parameters such as Return Loss (RL), Bandwidth (BW), Gain, and Directivity. In this paper, we propose a rectangular microstrip patch antenna with EBG substrates of different EBG patch width and analysis the performance of the proposed antenna compare with a conventional patch antenna using the same physical dimension using HFSS simulator. Here we show four analyses of our designed antenna and compare with the conventional microstip patch antenna. Comparison results show that, the performances of our proposed schemes are better comparing the conventional patch antenna.
