Abstract :
This paper presents a new broadband and high gain dielectric resonator antenna for millimeter-wave underground communications systems. The proposed antenna is composed of a microstrip feed, a cylindrical dielectric resonator, and multiple metallic strips stacked to a superstrate. This antenna is dedicated for the 60 GHz frequency band. Results show that the antenna has great performances especially in terms of bandwidth and gain. A bandwidth of 12.69 % at the centered frequency of 59.55 GHz and a gain of 15.40 dBi over the entire band (57 GHz to 64 GHz) are obtained. A maximum gain of 16.71 dBi has been achieved at 58 GHz. This antenna provides an improvement of 10.71 dBi compared to the conventional single DRA. With these performances, this antenna is suitable for wireless underground communication systems.
