摘　　要：根据瞬时超宽带天线的时域特点,仿真设计了一款超宽带TEM加脊喇叭天线,并对其频域和时域特性进行了初步研究,在频域内实现了3 GHz～18 GHz的超大带宽。在时域内进行了单个喇叭天线的时域信号测试,包括辐射的时域波形和峰峰值方向图。对该类天线的时域特性有了一定的认识。According to the time domain characteristic of instantaneous ultra wide band antenna, a TEM ridge horn antenna is designed and simulated. The antenna characteristic in frequency domain and time domain is studied. The frequency band is 3 GHz- 18 GHz. Moreover, the time signal is tested, including the time wave and peak pattern. Through the study, the time idiosyncrasy of this type of antenna is obtained.
