Parameter Improvement of MPA using Square Shape Reflector for S-Band Wireless Application

Abstract

A low profile MPA have been widely used for the application of RF and wireless system because of their small size, light weight and easy realization. In this project, a metal based reflector resonator is used to increase antenna gain by 2.796 dBi at 2.73 GHz resonant frequency. The proposed patch antenna is operating in 2.7GHz frequency band with impedance bandwidth of 2.6-2.73GHz. Parametric analysis of reflector height is done in order to obtained peak gain of 4.97dbi. The radiation of patch antenna shows broadside pattern with stable gain such that the antenna is suitable for wireless application in s- band. The proposed antenna design is simulated on CST software using FR4 substrate with relative permittivity of 4.3 and thickness of 1.6mm.
