Circularly Polarized Cylindrical Dielectric Resonator Antenna for 5G Applications

Abstract

In this paper, a cylindrical circularly polarized dielectric resonator antenna (DRA) consists of FR4 and RogersRO6010 in stacked form has been designed, fabricated and measured within the 5G frequency range of over 20 GHz. A power divider along has been used to split power input into two. The proposed antenna achieved a 24.5% S11 bandwidth which agree favorably with the 24.8% obtained using measurement. In terms of circular polarization, the designed DRA reported % 3dB Axial Ratio (AR) bandwidth using simulation. Additionally, the antenna achieved relatively high gain of ∼10.93dB at the resonant frequency.
