Compact rectangular DRA with high permittivity stacked resonator for RADAR applications
In this paper, we propose a new dielectric resonator antenna (DRA) loaded with rectangular ceramic of the BST (Ba0.8Sr0.2TiO3) material. The high permittivity of the material allows the shifting of the antenna resonant frequency from 10.77 GHz to 8 GHz (suitable for radar applications), achieving a size reduction of the resonator antenna about 67% compared to an ordinary DRA for the same resonant frequency. The numerical analysis was carried out using two electromagnetic simulators including the CST Microwave Studio in the time domain and the HFSS (High-frequency Structure Simulator) in the frequency domain. The numerical results issued from simulations are presented and compared in terms of the resonant frequency, antenna size, reflection coefficient, and radiation patterns.
