介绍了紧凑型 C 波段正模换能器的设计和测试结果。该传感器由四个正交排列在圆形波导中的矩形探头组成，设计用于在 WG13 频段工作。系统在 4.64-7.05 GHz 频率范围内的测量结果与仿真结果非常吻合，并显示交叉极化电平低于 -58 dB，回波损耗约为 -20 dB。整个波导带内正交偏振模式之间的插入损耗差异小于 0.18 dB。
The design and test results of a compact C-band orthomode transducer are presented. The transducer comprises four rectangular probes orthogonally arranged in a circular waveguide, designed to work in the WG13 band. Measurements of the system in the frequency range 4.64-7.05 GHz agree very well with simulation results and show a cross-polarisation level below -58 dB, a return loss of about -20 dB. and an insertion loss difference of less than 0.18 dB between the orthogonal polarisation modes across the full waveguide band.
