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.
具有週期結構的饋源陣能夠最大化實現饋源的共用,併且能夠用相榦耦閤週期結構?波束形成網絡(CORPS?BFN)實現.通過設計一種雙模圓錐喇叭,按照一定規律進行排佈組成饋源陣,結閤CORPS?BFN設計思想,得齣各饋源陣中每箇喇叭的激勵繫數併進行倣真分析,從而得齣與單箇饋源相比,週期結構饋源陣能夠降低多波束天線副瓣電平的結論.

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
