Abstract :
Recently, system designers have looked toward the higher frequency, shorter wavelength (to THz), consequently the device requires smaller and more precision. Many methods in microwave band are not feasible to THz. This paper describes a duplexer (Its main components is polarizing beam splitter and polarization converter.) works in the radar system set-up at 220GHz. After simulations, the exact model size is confirmed and the calculated data show a good result. These components have an advantage is easy to machining. At last, the main components have been fabricated and tested. And the experiment results show the feasible of this duplexer.
