PARAMETRIC PERFORMANCE ANALYSIS OF PATCH ANTENNA USING EBG SUBSTRATE

In recent years, microstrip antennas becomevery popular because of their interesting advantages of low cost, low profile, light weight, easy fabrication andease of analysis. Electromagnetic Band Gap (EBG) substrate is used as a part of antenna structureto improve the performanceof 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 antennacompare with a conventional patch antennausing the same physical dimensionusing HFSS simulator. Here we show four analyses of our designed antenna and compare with the conventional microstippatch antenna. Comparison results show that, the performances of our proposed schemes arebetter comparing the conventional patch antenna.
