摘要: 该文对一种矩形到同轴扇形渐变TE□10TE⊙01模式变换器的带宽特性进行了研究。分析了工作频带内竞争模式对工作模式的影响，探讨了滤模加载对改善模式转换性能的作用。模拟结果表明，滤模加载可以削弱竞争模式对工作模式的影响。加滤模结构后，模式变换器工作在Ku波段时，在模式转换效率大于70%的情况下，带宽可以大于700MHz。Abstract: Bandwidth property of mode conversion from the TE□10 mode of a rectangular waveguide to the TE⊙01 mode of a coaxial waveguide is studied. The influence of mode competition on operating mode inside the bandwidth is analyzed and the effect of mode filter on mode conversion property is discussed. The simulation results with Ansoft HFSS show that the influence of mode competition can be weakened with a mode filter, and the operating bandwidth of 700MHz can be reached while the mode conversion efficiency is more than 70% at Ku band for the new structure.
