Abstract

A novel design for orthomode transducer (OMT) with an embedded bandpass filter function is proposed in this letter. The OMT consists of a common cavity resonator and four independent cavity resonators, which are coupled with each other via vertical and horizontal slots. By utilizing the two orthogonal resonant modes in a cavity resonator, a filtering OMT with different center frequency is achieved. To substantiate the efficacy and precision of the proposed design method, a filtering OMT was fabricated and subsequently subjected to measurement. The experimental results indicate that the proposed structure can achieve good filter function and high isolation over 40 dB between the output ports.

基于腔腔谐振器的滤波正交换能器设计

本文提出了一种具有嵌入式带通滤波器功能的正交换能器（OMT）的新设计。OMT由一个共腔谐振器和四个独立腔谐振器组成，它们通过垂直和水平槽相互耦合。利用腔腔谐振腔内的两种正交谐振模式，实现了不同中心频率的滤波OMT。为了验证所提出的设计方法的有效性和精度，制作了一个滤波OMT并随后进行了测量。实验结果表明，该结构具有良好的滤波功能，输出端口之间的隔离度在40 dB以上。
