Performance Analysis of Dual Band Circularly Polarized Hybrid Dielectric Resonator Antenna

Abstract

The performance analysis of asymmetrical slot-based hybrid Dielectric Resonator Antenna (DRA) is presented in this paper. The volume of proposed DRA is 60mm x 60mm x 1mm and the DR material used is Alumina ceramic with dielectric constant of 9.8 various parameters studied. The proposed DRA possesses two resonances at 2.65GHz with a bandwidth of 900 MHz and 3.47 GHz with a bandwidth of 800 MHz. The Axial ratio is observed as 2.5dB at the bandwidth of 200MHz. The maximum gain obtained is 4.99 dBi. The suggested DRA meets the Wi-Max and basic 5G applications.
