Summary:This paper presents a new broadband and high gain dielectric resonator for millimeter-wave underground communications systems. The proposed antenna is composed of a superstrate, a coplanar waveguide feed, and a rectangular dielectric resonator. This antenna is designed to cover the ISM frequency band at 60 GHz (57 GHz-65 GHz). This antenna was numerically designed using CST microwave Studio simulation software package. Simulated results show that the antenna has good performances especially in terms of bandwidth and gain. A bandwidth of 17.4% at the centered frequency of 60.98 GHz and a gain of 11 dB over the entire ISM band have been achieved. A maximum gain of 14.44 dB is obtained at 60 GHz. This is an enhancement of 9 dB compared to a single DRA.
