“微波技术与天线”课程中的二分性定理

Bisection Theorem in the Teaching of Microwave Techniques and Antennas Course

本文以电路的二分性定理在射频/微波技术领域的演变为基础,引出射频/微波对称网络的奇偶模分析方法,并以二分性定理和奇偶模分析法的导出公式的应用为例,说明典型的单、双对称电路和射频/微波对称网络网络参量的简单推导过程。结果表明,采用二分性定理和奇偶模分析法导出的对称电路和射频/微波对称网络的阻抗和散射参量与常规方法所得的结果完全相同。

Based on the evolution of bisection theorem in the field of RF/microwave techniques, the odd and even mode method for symmetrical multiple port networks is concisely introduced. As the application example for the bisection theorem and odd and even mode method, we illustrate the derived process for the impedance and scatter- ing parameters of typical simple and double symmetrical circuits or RF/microwave networks. It is shown that the bisection theorem and odd-even mode method can ters for the symmetrical circuits or RF/microwave provide the same results of the impedance and scattering parame- networks as those obtained with conventional methods.
