High Gain Disc Resonator Antenna Array with CPW Coupled for THz Applications

This paper introduces a disc resonator antenna array with compact size and wide band for THz applications. The disc antenna is designed based on modified SOG technology platform from high resistivity Si. A Dielectric Waveguide (DWG) is matched with the disc dielectric antenna using CPW feed. The CPW feed is designed on the Pyrex side of the Si wafer bonded to the Pyrex. The proposed antenna is designed to operate from 325 GHz to 500 GHz with good return loss. The endfire and broadside antennas are introduced with high gain about 17 dB. The antenna has high efficiency and low cost.
