Performance Improvement of Microstrip Patch Antenna Using Defected Ground Plane
In this paper, the authors present a design of planar Microstrip Patch Antenna (MPA) with full ground plane which is able to operate at 5.5GHz frequency with 200MHz band. The return loss at 5.5GHz is 29.5dB for inset feed antenna. Maximum gain of this antenna is 5.7dB. Return loss is improved after introducing a pyramidal shaped defected ground plane at same frequency. Now, the return loss is 36.81dB. All simulation work has been done on HFSSV10.
