摘要

介绍了一种三重对称三脊波导正交换能器的设计。这种脊状波导设置增强了结构的单模带宽，确保不激发高阶模式，从而消除了当组件用作喇叭天线馈电网络时不想要的共振。模拟性能显示，在整个3:1的工作带宽上，回波损耗低于- 20 dB。

Tri-Ridged Waveguide Orthomode Transducer

The design of a three-fold symmetry tri-ridged waveguide orthomode transducer is presented. This ridged waveguide setup enhances the single-mode bandwidth of the structure, ensuring that higher-order modes are not excited which in turn eliminates unwanted resonances when the component is used as a horn antenna feeding network. The simulated performance shows a return loss that is below - 20 dB across the entire 3:1 operating bandwidth.
