Beam optimization design method for satellite-borne multi-feed-source synthesis multi-beam antenna

According to the beam optimization design method for the satellite-borne multi-feed-source synthesis multi-beam antenna, the antenna is composed of a reflector and a feed source array, and coverage area beam design is carried out through a multi-feed-source synthesis beam mode, antenna parameter configuration, a feed source array excitation coefficient and a beam forming network topology structure. The method solves the problem of rapid, accurate and optimal design of beams of a large-scale multi-feed-source synthesis multi-beam antenna, meets the beam performance of high gain, high C/I and low cross polarization in the working frequency band of a service area, and has a wide application prospect in the field of high-throughput/very high-throughput communication satellites. 一种星载多馈源合成多波束天线波束优化设计方法，天线由反射器和馈源阵列组成，通过多馈源合成波束方式、天线参数配置、馈源阵列激励系数、波束形成网络拓扑结构进行覆盖区波束设计，解决了大规模多馈源合成多波束天线波束的快速、精确、优化设计问题，满足服务区域工作频段内高增益、高C/I、低交叉极化的波束性能，在高通量/甚高通量通信卫星领域内具有广阔的应用前景。
