| Abstract: | According to the characteristic of the impedance converter in multimode feed network,the three-port network parameters of the impedance converter and some methods for its measurement are analyzed.Based on the applying of the available two-port network analyzer,the port impedance matching is considered,and different measuring port environment transformation formula is obtained,the measurement of three-port scatter parameters for the impedance converter in multimode feed network is researched,the mixed-mode S-parameters are used to verify the actual measured data.The method has provided the effective foundation for the optimization and design of the multimode feed network. |
