Abstract— In this paper, a novel feed network for patch antenna with star shape has been presented. This antenna works at THz band having important. Designed antenna at 200GHz with new feed network increased bandwidth and compared with reported similar antennas has capability that bandwidth change from 10% up to 53%. Proposed antenna has engineered capability between bandwidth and gain of antenna.
