A 77ghz dielectric resonator antenna array using dielectric image insular guide

A double-sided Dolph-Chebyshev amplitude distribution dielectric resonator antenna (DRA) array using dielectric insular image guide (DIIG) is presented. In order to improve the gain, the DRA array is designed in double-sided of the DIIG, as a mirror array of DRA blocks on one side. The Dolph-Chebyshev amplitude distribution is employed here to suppress the sidelobes of the DRA array. A double-sided 7-element linear DRA array is designed and optimized using HFSS13.0, and a high gain of 14dB at 77GHz has been achieved.
