Deign of Broad Band Gap-Coupled Microstrip Antenna Using Microwave Office 7.5

Abstract

The objective of this paper is to design a compact andbroadband microstrip patch antenna which operates at 2.9GHz center frequency with parasitically couplingrectangular microstrip antenna RMSA. Several parasiticallycoupled geometries are studied here.Thes are: radiatingedge and non radiating edge gap-coupled RMSA withparasitic patches, one, two and four parasitic patches arebeing presented. The antenna has been analyzed usingMicrowave Office package software 7.5 in 2007. Thisproposed structure can have an operating bandwidth morethan six times than that of the conventional rectangularpatch antenna
