摘要

本文介绍了一种紧凑型正交换能器的设计。简要介绍了波导omt的分析方法，包括模式匹配法和混合方法。介绍了三种类型的紧凑型OMT:尺寸较小的介电填充OMT，使用衬底集成波导实现的平面OMT，以及带有紧凑型隔膜的双频Tx/Rx OMT，以提高隔离度。通过测量验证了双频Tx/Rx和SIW omt。同时指出了设计小尺寸多频段omt所面临的挑战。

Design of Compact Orthomode Transducers

This paper presents the design of compact orthomode transducers (OMTs). Analysis methods for waveguide OMTs, including the mode-matching method and hybrid methods, are briefly reviewed. Three types of compact OMTs are described: a dielectric-filled OMT with reduced size, a planar OMT implementing using substrate integrated waveguide, and a dual band Tx/Rx OMT with a compact diaphragm to improve isolation. The dual-band Tx/Rx and SIW OMTs are verified by measurements. Challenges for designing multi-band OMTs with compact size are also pointed out.
