摘要

针对韩国VLBI网络，研制了一种由正交换能器(OMT)和90度差分移相器组成的33~50 GHz双圆偏振器。OMT基于弯曲双脊结构，移相器采用四脊波导设计。所设计的圆偏振器的带宽约为41%。

A Broadband Q-band Dual-Circular Polarizer for Millimeter-Wave VLBI Observations

A 33~50 GHz dual-circular polarizer combining of an OMT(Orthomode Transducer) and a 90-deg differential phase shifter has been developed for Korean VLBI Network. The OMT is based on curved double-ridge structure and the phase shifter is designed using quad-ridge waveguide. The bandwidth of the designed circular polarizer is around 41 %.
