摘要
针对两线一地构成的耦合传输线，导出其正弦电压、电流相量方程．方程中具有和型二次参数波阻抗Ｚｃ１和传播常数γ１以及差型二次参数波阻抗Ｚｃ２和传播常数γ２．提出在耦合传输线终端开路和短路的条件下．通过在起端测试．确定这两组二次参数的原理和方法．经实验验证本文提出的耦合传输线参数测试方法是有效的．
This paper gives the phasor voltage and current equations of the coupled transmission lines with two parallel wires and the earth. In the equations, the second parameters, propagation constant and wave impedance, of sum mode γ1 and Zc1 and also their difference mode γ2 and ZC2 are concerned. The principle and method of measurement that determines these two sets of parameters by the open circuit and short circuit measurements at the beginning terminals are presented. This method has been proved to be effective through experiments.
