Abstract

The design of a new phased array antenna for S-band is designed in this paper. The structure of the new antenna is based on the traditional microstrip quasi-Yagi antenna. The G type micro-strip line is designed on the back of the antenna for feed line. Two director elements and two driver elements are increased to improve the gain. The top of the director elements is grooved to expand the bandwidth. This antenna is designed and analyzed by comparing with simulation software and antenna test. The results of the modified quasi-Yagi show a relative bandwidth about 40% for Voltage Standing Wave Ratio(VSWR) of less than 2 and the maximum gain about 6dB at center frequency 2.4GHz. The method of reasonable structure design is testified can effectively improve the bandwidth and gain of this antenna. It has good application prospects.
