Abstract

This paper presents a 20-Gbit/s unidirectional wireless data transmission system with a 120-GHz-band wireless link using orthomode transducers (OMTs). The OMTs are used for polarization multiplexing unidirectional transmission of 120-GHz-band wireless link. We designed and fabricated a new finline OMT whose group delay is improved by adjusting waveguide length. The measured group delay is 43 ps. Using the finline OMT, we developed new unidirectional wireless equipment that can transmit two channels of 10-Gbit/s data using cross polarization multiplexing. With this wireless equipment, we succeeded in the20-Gbit/s wireless data transmission and and 12-ch high definition television (HDTV) signal transmission.
