- A cost effective low temperature co-fired ceramics antenna with wide beamwidth and high gain at 77 GHz is presented. This antenna consists of an aperture coupled dielectric resonator antenna which provides high gain and wide beamwidth. The vias surrounding the dielectric resonator act as a metallic fence, and prevent signal leakage. The top surface of this antenna is covered with dielectric layer, and no metal pattern was exposed to the air. Fabrication cost can be reduced by eliminating the expensive gold plating process due to this top passivation layer. The simulated results of the proposed antenna show a wide beamwidth of 86째 and a peak antenna gain at 76.5 GHz of 7.5 dBi.
