摘要
基于耦合波理论的基础上,分析了TE01-TE11模式转换器的特性和半径渐变指数,讨论了中心轴线弯曲下的圆波导模式转换器,对中心频率33 GHz的波导进行了模拟设计、仿真,在保证带宽的前提下,尽力降低转换器的长度和提高转换效率,最后达到了97.82%的转换效率,带宽达到2 GHz。
Based on the basis of coupled wave theory, the gradient index characteristics and radius mode converter of TE01-TE11 mode converter are analyzed, then the center axis of the circular waveguide mode bending down of center frequency converter is discussed. The waveguide at 33 GHz is simulated and designed. Before the guarantee bandwidth premise, the length of the converter can be reduced and the conversion efficiency can be improved, and finally the conversion efficiency 97.82%, 2 GHz of bandwidth can be achieved.
