摘　　要：研究了渐变槽线宽带宽角扫描天线阵列的关键参数进行了研究,提出了2种新的改善扫描驻波的方法对渐变槽线天线的研究。一是天线单元内部的结构参数,包括带状线开路段、圆形槽谐振腔、槽指数率、槽长度;另一个方面是阵列中的排布,包括阵列栅格距离、栅格形状。仿真分析借助HFSS进行,最后给出了结果,带宽大于3∶1,E面H面扫描角大于45°。The key parameters of tapered slot antenna arrays are shown which affect wide-band and widescan performance of the array.The study of the TSA,which also can be called Vivaldi antenna,be divided to two parts,one part is antenna unique parameters,which consists of strip-line open stub,circle slot cavity and open rate of slot line,the other part is array parameter,which consists of grid distance and figure of grid.The result is provided which has been studied by HFSS,the bandwidth is more than 3∶1 and for a scan volume of not less than 45°in both E-Plane and H-Plane.
