The Performance Analysis of the Antenna System Designed by Using The PI Matching Circuit

Abstract

Impedance matching networks are used extensively in radio communications. In this study Pi matching circuit has been used. This circuit impedance region has been investigated analytically under the variable load condition. The rectangular microstrip antenna was designed at 2.5 GHz frequency by using microstrip feed line. Better return loss level has been obtained for this antenna using pi matching circuit. It is shown that theoretical, simulation and laboratory results are good agreement
