Perturbed Higher Order Wideband Dielectric Resonator Antenna with Low Cross-pol for Millimeter Wave 5G Applications

A singly fed high gain, wideband Dielectric Resonator Antenna (DRA) is designed here which can be used for millimeter wave 5G applications. The simulated gain of the aperture fed DRA is 8.33 dBi and the simulated impedance bandwidth is 3 GHz which is from 26.56 GHz to 29.56 GHz. The percentage impedance bandwidth of the antenna is 11.53 percent. A H shaped slot has been done on the ground plane over which the DRA is placed and is fed by a microstrip line below the substrate. A vertical cylindrical hole has been made in the DRA which excites it to higher order mode TE21z. The cylindrical hole has also enhanced the gain of the DRA to 8 dBi.
