Recently, system designers have looked toward the higher frequency, shorter wavelength (to THz), consequently the device requires smaller and more precision. And this paper describes a polarization converter works in the radar system set-up at 225 GHz. Its working principle is similar to the optical diffraction. After simulations, the model size is confirmed and the data show a good result. And this component have an advantage is easy to machining. It also can be used in other frequency band through adjusting its size.
