Abstract
In this paper, a novel compact dielectric resonator antenna (DRA) is reported. It operates at 28 GHz with a bandwidth of 2.8 GHz. It is a composite structure, consisting of two-quarters of hemispherical DRA (qHDRA) and one rectangular DRA (RDRA). A passive microstrip slot aperture (MSA) coupled feeding technique is designed to enable a suitable magnitude and phase excitation of the DRA for radiation. The results for reflection coefficient, bandwidth, gain, radiation pattern, and E-field strength are analyzed using Ansoft High-Frequency Structural Simulator (HFSS) [1]. The peak gain of the proposed antenna is about 6 dBi. Also an impedance bandwidth (IBW) of over 10% and an efficiency of 99.5% are observed. The proposed antenna structure is a good candidate for future 5G applications.
