Design of Simple PCMPA for X Band Applications

Proximity coupling feed is a novel electromagnetic coupling system to improve the radiation characteristics of planar antenna. In this paper, such feed technique is implemented to excite circular patch antenna with modified ground. The modeling and simulation results shows that the radiation characteristics like return loss, voltage standing wave ratio (VSWR) and gain have improved with the slot. When compared to without slot for Proximity fed Circular disk patch antenna. The simulation is carried out in HFSS and the analysis is carried using S11, VSWR and radiation pattern.
