RECTANGULAR PATCH ANTENNA FOR INFINITE AND FINITE GROUND PLANE.

Antennas with low profile, simple, light weight are in demand. In this paper rectangular patch antenna is described with both infinite and finite ground plane. Here, microstrip line feed method is used to excite the antenna This paper presents the design of rectangular patch antennae on FR-4 substrate with dielectric constant 4.4 with loss tangent 0.019.The dimension of antennae is 13.5mm x 18mm for resonant frequency of 5GHz.
