Abstract
This paper introduces an antenna for Automotive Radar to operate at 77 GHz. The proposed antenna consists of a hybrid radiator and dielectric resonator. The hybrid radiator is a circular patch that feed by aperture method and the dielectric resonator is ring that feed by the circular patch to operate at 77 GHz with high gain 12 dB for one element. The EBG structure is implemented on the top layer to widens the proposed band, gives high gain and to reduce surface waves. The compact size of one element 3.5mm×3.5mm×l.16mm to operate from 75.3 GHz to 80 GHz with gain 12.3 dB.
