Multimode Feed Network Sub-structure Analysis And Measurement Methods

Feed network is an important part of short-wave multimode multi-feed antenna system.The design of feed network is a pivotal technique in the process of projecting antenna system.Above all,this paper expounds the basic notion and procedure of analyzing and designing feed network applying the substructure analyzing theoretics of interconnect-net.Basing on these jobs,some radical methods of analyzing and measuring the substructure of feed network are presented.Using these methods,substructure is analyzed and measured.Finally,a measured database of substructure of feed network is established.
