摘　　要：根据紧缩场天线测试系统对馈源的要求,选择缝隙平面馈电结构与TEM喇叭组合的新颖技术实现馈源的超宽带、电小尺寸、天线的E面和H面方向图3dB波束宽度等化,从而使馈源达到高性能、体积小、重量轻和容易安装等目的,满足低频紧缩场天线测试系统的要求。According to the design request of ultra-wideband feed in Compact Antenna Test Range,a novel antenna com- posed of a tapered slot antenna and a TEM horn is investigated.The construct of this antenna is analyzed and the design method is given.Experiment results show that the VSWR of the antenna is less than 2 from 0.16GHz to 3.1GHz,and the antenna has the characteristics of low cross polarization,good direction patterns of E-and H-planes and small electrical size.It satisfies the re- quest d the CATR.
