一、引言由于不同元件、微波组件和各种各样的传输导体的集成,不仅器件的性能得到了改善,而且降低了成本。通常使用的传输手段有带状线、微带线、槽线共面波导,以及悬置带线。最近又出现了一种叫做“类带状线微带”的新型结构,如图1所示。这种传输方法比带线的 I. Introduction Due to the integration of different components, microwave components and various transmission conductors, not only the performance of the device has been improved, but also the cost has been reduced. Commonly used means of transmission stripline, microstrip line, slotted coplanar waveguide, and the suspension line. Recently, a new type of structure called “stripline microstrip” emerged as shown in Figure 1. This method of transmission than with the line
