摘　　要：针对多模馈电网络中阻抗变换器子结构的特性,对阻抗变换器三端口网络散射参数的获取和测量方法进行了详细分析.考虑端口的阻抗匹配,推导出不同测量端口环境下的转化公式,对用二端口网络分析仪测量阻抗变换器的三端口散射参数进行了实际测量并用混合模式散射参数对该方法进行仿真比较,证明了该方法是正确的,为整个馈电网络系统的设计和优化提供有力的帮助.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 muhimode feed network.
