本文从分析和设计两个方面分别对E-面耦合和H-面耦合微带被导过渡接头进行了研究。在分析中，首先应用反应的概念得到输入阻抗的谱域表达式，对谱域积分分别用留数法和变换路径积分法进行计算，经比较发现交换路径积分法是一个更加有效的方法。在分析的基础上我们用遗传算法对微带波导过渡进行了优化设计，计算结果和实验结果吻合较好。
In this paper, the E-plane coupling and H-plane coupling microstrip guided transition joints are studied respectively from the aspects of analysis and design. In the analysis, firstly, the concept of reaction is used to obtain the spectral expression of input impedance. The integral of spectral domain is calculated by using the residual method and the transform path integral method, respectively. It is found that the path integral method is a more effective method. Based on the analysis, we use genetic algorithm to optimize the transition of the microstrip waveguide. The calculated results are in good agreement with the experimental results.
