摘　　要：提出了一种可以应用于电子战的双脊波导魔T接头,介绍了它的基本原理,运用模式匹配和迭加的方法,对双脊波导魔T接头进行了分析和计算,设计了一种新型的双脊波导魔T接头。它不仅工作频带比标准波导魔T宽很多,而且结构尺寸大大减小,实现了宽频带功率分配器、合成器和射频电子开关的功能。实物测试的结果表明其性能良好。A novel double-ridge waveguide Magic T junction is proposed that can be widely used in EW. The basic principles are introduced, and the analysis and computing is done using mode-matching technique and superposition method. A computed result of S parameters can be obtained and then a new double-ridge waveguide Magic T is designed according to the simulation result, which is with much smaller dimension and much wider bandwidth than the standard rectangular waveguide. It can work as a splitter/combiner as well as a switch. Measurement shows the new double-ridge waveguide Magic T works well.
