窄边双脊波导传输特性的分析

摘要

文中基于矢量有限元法对窄边双脊波导传输特性进行分析,分别在波导的宽边和窄边加载T型脊,计算波导的截止波长和单模带宽.通过比较脊位置的变化,给出不同模式的场图,并且指出了这种新型加脊波导的优缺点.%The transmission characteristics of short-side double ridged waveguide are analysed by the vector finite-element method. When the T-shaped ridge are located on the waveguide short side and wide side,the cutoff wave length and single-mode bandwidth are calculated respectively. By means contrasting with the effect of the ridge location, this paper gave the field pattern of different mode and pointed out the merits and drawbacks of this new type ridge waveguide.
