Exploration of MgTiO3-CaTiO3 Ceramic-Based Dielectric Resonator Antenna for Sub-6 GHz 5G Communication Application

Abstract

There has been extensive research on microwave dielectric materials considering their applications in 5G communication technologies. In this work, the microwave dielectric performances of 0.95MgTiO3−0.05CaTiO3 (MCT) ceramic for sub-6 GHz frequency 5G application have been reported. The solid-state reaction technique was used to develop the MCT ceramic. The structural as well as dielectric properties of MCT were systematically examined. X-ray diffraction (XRD) was used to examine the crystalline phase of the MCT sample. The microwave dielectric properties, including relative permittivity, temperature coefficient of resonant frequency, and quality factor of MCT were measured. Using MCT ceramic as the resonator, a dielectric resonator antenna (DRA) has been simulated using HFSS software, which realizes that the S11 curve is in good accordance and that efficiency is high at 5.22 GHz. The extraordinary performances indicate that MCT ceramic is a potential candidate for 5G application.
