Abstract
This paper presents a wideband circularly polarized (CP) dielectric resonator antenna (DRA). The thin cross-shaped antenna of high permittivity is excited by two orthogonal microstrip lines with 90° phase difference resulting in circular polarization. The general design principles are proposed in this paper and a commercial full field analysis software, based on Finite-Element-Method (FEM), is employed to fine-tune the proposed antenna. The experimental results show a good agreement with simulation and demonstrate a broadside CP bandwidth of 13.2%.
