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 %.
