Abstract

This letter presents an analysis of the impedances of differential feed microstrip rectangular patch antennas. It is shown that the impedance of a differential feed antenna exhibits cosine squared behavior over the feed distance. We present improved expressions for calculating the impedance match feed positions of a differential feed rectangular microstrip patch antenna with given dimensions, on the base of which we designed two antenna prototypes. Both simulation and measurement results match our theoretical prediction.
