Abstract
In this paper a compact Rectangular Micro-strip Patch Antenna (RMPA) with single feed is presented. Resonant frequency of proposed antenna is shifted toward lower side by introducing rectangular slot at the upper edge of patch. FR4 substrate having with thickness 1.6 mm is used as substrate material for the design of proposed antenna Performance of antenna in terms of Gain bandwidth is improved by adding a small piece of rectangular patch within the area of the rectangular slot. Antenna size has been reduced 48.9% when compared to conventional RMPA. The return loss of antenna of the antenna at resonant frequencies 3.3 GHz, 4.7 GHz and 6.7 GHz are -15.68dB,-17.71 dB and -33.82 respectively. Conventional square micro strip patch antenna gives return loss -10.91 dB at 7.4 GHz frequency. Ansoft HFSS V13.0.0 (high frequency structure simulator) software is used to investigate the characteristics of this antenna.
