Abstract

Microstrip patch antennas with transmission line feed are widely being used in developing harmonic transponders. The paper presents a novel technique of using a single microstrip line for feeding, impedance matching and frequency tuning of patch antenna instead of using separate transmission line and stubs. The impedance matching and frequency tuning is carried out by varying the width and length of the feed respectively. The paper validates the technique both by simulation and experimentally developing 10.6 GHz circularly polarized patch antenna.
