A Wideband Dielectric Resonator Antenna for 5G Mobile Applications

This paper proposes a wideband dielectric resonator antenna (DRA) at 3.5 GHz. 5G mobile technology requires a wide bandwidth and high gain more than 1 GHz and transferring signal in directive radiation pattern. Hence, DRA technique is used for wideband characteristics. The proposed antenna is designed with implementation of U-shape air filled inside basic structure. The U-shape inside patch are implemented in order to increase the bandwidth and gain. The proposed antenna is simulated using HFSS software and then printed on the FR4 substrate with thickness of 1.6 mm and permittivity of 4.4. The antenna performance achieved a fractional bandwidth of 1.69 GHz and a gain of 5 dB. The proposed antenna is suitable to be implemented in the future 5G mobile applications.
