The characteristics, principles and design considerations of the patch antenna are introduced in this paper. According to the aperture-coupled feeding technique, the antenna is simulated and optimized in the design process. The simulation results show that the structure of the patch antenna is simple, the relative bandwidth （VSWR 〈 2） of the antenna can achieve 21% and the gain is high. Through simulation, the conclusion that the patch antenna is practicable can be obtained. This kind of patch antenna is useful to upgrade the performances of electronic warfare equipments.
