摘要

介绍和比较了两种不同设计的正交换能器，用于即将在美第奇纳的意大利射电望远镜ku波段接收机，展示了设计细节，描述了数值模拟，并讨论了制造和测试结果。这种正交换能器提供了低损耗和相位匹配之间的权衡，根据不同的初始要求，最终的接收器结构必须被冻结。两种设计都在工作的13.5-18.1 GHz ku波段表现出高性能。其中一种OMT设计已经制作完成并进行了测试，结果与仿真结果非常吻合。

Design of two Ku-band orthomode transducers for radio astronomy applications

Two different designs of orthomode transducers for the coming Ku-band receiver of the Italian radio telescope in Medicina are presented and compared, showing design details, describing numerical simulations and discussing manufacturing and test results. Such orthomode transducers provide a tradeoff between low-loss and phase-matching, according to different initial requirements where the final receiver architecture has to be frozen. Both designs show high performance over the operative 13.5–18.1 GHz Ku-band. One of the OMT designs has been fabricated and tested, showing results in very good agreement with simulations.
