U-H SHAPED RECTANGULAR PATCH ANTENNA FOR TUNING RESONANT FREQUENCY IN S- BAND

Abstract: This paper includes, designing of U-H shaped rectangular patch antenna by geometrical modification of a rectangular patch antenna. Initially a simple rectangular antenna is projected to resonate at frequency 2.89GHz. The antenna is modified in the form of U and H shape to investigate tuning of resonant frequency within the band. The designing of antenna is done by using high frequency simulation software CST Microwave Studio followed by measurement. The overall dimension of the antenna is kept constant while modifying the antenna from simple patch to U and H shaped letters
