Design & Analysis of Proximity Fed Circular Disk Patch Antenna

To have efficient communication microwave antennas play major role, keeping this in mind we have designed a new micro strip antenna using proximity feeding in the range of 5GHz. The new design has been validated and has proved to be better than other designs. The bandwidth has been in the satisfactory range and also gain. This paper focus on the bandwidth enhancement of micro strip circular patch antenna by introducing a slot in the ground plane of length 4mm and width 4mm on the ground plane. The proposed antenna is excited through the proximity coupled feed technique and the antenna design and parametric studies has been executed using IE3D software. The resonate frequency is 5GHz having gain 4dBi.However it has not affected any quality parameter of the antenna. The results of new design are in accordance to the theoretical expectations.
