Optimizing Microstrip Patch Antenna Using Array

Anil Kumar Dubey

Abstract: In this paper wideband E shape Microstrip Patch Antenna operating at frequency of 5.8 GHz is designed and its performance is optimized using array concept. Two antenna array is proposed of E-shape patch 1?2 and 2?2 array ? these antennas are designed and its performance is analyzed by return loss, VSWR, current distribution and smith chart. Aim is to enhance bandwidth so that disadvantage of narrow bandwidth of patch antenna can be overcome and patch antenna will be used worldwide for electronic communications applications.
