Abstract
In this paper, a U-slot rectangular microstrip patch antenna is designed in order to overcome the narrowband characteristic and gain broader band. The antenna has dual-band characteristics, so it has wider operating bandwidth. The antenna works at Ku-band and the center frequency is 16GHz. The characteristics are analyzed and optimized with Ansoft HFSS, the simulation results show that the absolute bandwidth and gain of the antenna unit are 2.7GHz and 8.1dB, and of the antenna array are 3.1GHz and 14.4dB. The relative bandwidth reaches to 19.4%, which is much wider than the general bandwidth of about 1% to 7%.
