周期结构馈源阵对多波束天线性能的影响

内容简介：具有周期结构的馈源阵能够最大化实现馈源的共用,并且能够用相干耦合周期结构?波束形成网络(CORPS?BFN)实现.通过设计一种双模圆锥喇叭,按照一定规律进行排布组成馈源阵,结合CORPS?BFN设计思想,得出各馈源阵中每个喇叭的激励系数并进行仿真分析,从而得出与单个馈源相比,周期结构馈源阵能够降低多波束天线副瓣电平的结论.

Abstract：The feed source array with periodic structure can realize the maximization sharing of feed source,and can be easily achieved by coherently coupling periodic structures?beam forming network(CORPS?BFN). A dual mode conical horn was de?signed and arrayed to form feed source array by a certain law. The excitation coefficient of each horn in the feed source array was got and simulated in combination with design concept of CORPS?BFN. According to the detected results,comparing with sin?gle feed source,the feed source array with periodic structure can lower the side lobe level of multi?beam antenna
