| 摘 要： | 波导功率分配器是微波、毫米波系统中常用的重要部件，但是传统匹配结构由于加工的困难在W频段很难实现。本文利用基于亥姆霍兹弱形式的有限元法设计了一种圆弧匹配结构，这种结构与铣床刀头的轮廓吻合，因而可以方便地加工出来。文中给出了两个设计实例，计算结果与实验结果吻合的很好。

| Abstract: | Waveguide power divider is an important component in microwave and millimeter wave systems, however, traditional matching structures are difficult to be realized at W band caused by the machining difficulties. So in this paper, a kind of arc structure is designed using the finite element method which is based on the weak form of Helmholtz equation; this kind of structure gears with the contour of the milling cutter and can be manufactured easily. Two design examples are given in this paper, numerical and experimental results agree with each other very well. |
