摘要
介绍一种抗干扰能力强的圆极化天馈系统,系统架构简洁可靠,其最大特点是从系统角度出发,利用各元器件特点,采用分级式滤波,减小了单个滤波器的设计难度,甚至可以在不单独设计滤波器的情况下解决系统的干扰问题。
A circularly polarized antenna and feeder system is introduced with strong anti-interference capability.The system architecture is simple and reliable,and its biggest feature is that from the perspective of the system,hierarchical filtering is adopted by using the characteristics of various components to reduce the design difficulty of a single filter,and the interference problem of the system can even be solved without designing the filter separately.
