Abstract

A compact microstrip patch antenna for 5 GHz is proposed. It presents the very small size at resonance (5 GHz), which represents a surface reduction of 60% compared with a conventional microstrip patch antenna. The branch line coupler is used for 900 phase shift between two vertical feed and equal power coupling. The proposed antenna exhibits a gain of 5.1 dBi to 5.5 dBi for E-plane in the range of its bandwidth, which is 60 MHz.
