Abstract

This paper presents a compact and high-isolation finline ortho-mode transducer (OMT) for a polarization division duplex 120-GHz-band wireless link. We designed and fabricated a new finline OMT which suppresses the oscillations on the finline without using resistive card. The measured cross polarization discrimination and isolation are more than 23 and 50 dB, respectively, across the entire occupied bandwidth of the 120-GHz-band wireless link. Using the finline OMT, we succeeded in experiments for 10-Gbit/s bi-directional and 20-Gbit/s uni-directional communications.
