摘要
匹配问题在微波技术中极其重要,也是微波系统中一个很重要的环节。利用三销钉匹配结构对连接在微波系统中的矩形波导(如BJ-26和BJ-22型)的匹配问题进行了研究和比较。将不同的销钉插入深度、端口反射系数、等效输入阻抗以及此时的矩形波导型号这些数据联系起来,形成一个对应关系。在微波系统中,调整销钉位置到固定位置可以对接有相同负载的不同型号的矩形波导实现阻抗匹配。
The matching is not only an important part in microwave technique, but also a significant aspect in the microwave system. In this paper, it researches and compares the matching of different types of rectangular waveguides on the basis of the three dowels matching unit. The purpose is to establish a coincidence relation by systemizing these data such as different depth of dowels,the reflection coefficient and the equivalent impedance at the port and the type of rectangular waveguide. It is convenient to achieve the matching through adjusting the dowels to the fixed depth.
