Multiband rectangular dielectric resonator antenna for 5G applications

This paper introduces the design and simulation of multiband dielectric resonator antenna (DRA) for the fifth generation (5G) of cellular networks. The radiating element is a unique rectangular shaped DRA element with a distribution feeding technique based on micro-strip feed line coupled via an elliptical slot. The feed position and configuration has been deliberately designed for optimized matching. The structure is approximately 40mm×48mm in size, conceived on Arlan dielectric substrate. The antenna has been optimized for the 10.5–17 GHz frequency bands. Simulated return loss, radiation pattern and gain over the frequencies of interest have been presented. The proposed antenna structure is a good candidate for future 5G cellular applications.
