Design of Dielectric Resonator Antennas for 5G Communications Systems

Abstract

This paper presents two promising designs of dielectric resonator antennas (DRAs) for 5G applications. The first design is a rectangular DRA, and the second is tetraskelion-shaped DRA. Both designs are fed by a microstrip line through aperture coupling, which is an effective feed mechanism and more efficient in energy coupling compared with the other types of feeding techniques. From the simulation results, it can be observed that the proposed antennas achieve an impedance bandwidth from 24 to 29 GHz. The proposed antenna designs give the appreciable gain and radiation pattern within the frequency band.
