Abstract: Integration of RF circuit components is required to make the antennas more compact and robust and is a trend in wireless application now-a-days. The micro strip antenna of patch variety is able to satisfy the requirement, but the disadvantage is reduced gain and reduced band width. The gain has a range of 1-2 dB. So in order to increase the gain as well as band width, the substrate with low dielectric characteristics and higher thickness can be used. However, thickness increases surface waves. So, proper thickness of the substrate is required. This paper proposes a micro strip patch antenna based on a special design (pentagon) suitable for resonant frequencies in the range of 7.6 GHz to 7.9 GHz. So the analysis has been done by means ofAnsoft HFSS software V 17.0 by taking Rogers RT/Duroid 5880 ™ as substrate material into consideration.Subsequently the gain, band width, radiation pattern and return loss has been evaluated with equivalent designs.
