“…The achieved broadside CP bandwidth of such structurally simple antennas remains normally below 7%. In contrast, other designs utilize complex geometries [10,11], sophisticated feed network [12] or additional hardware [13,14] to achieve wider CP bandwidth. This does not only increase the manufacturing difficulty and cost but usually results in bulky antenna configurations.…”

-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%.

Abstract-In this paper six novel Dielectric Resonator Antennas (DRAs) providing Circular Polarization (CP) using single probe feeds are proposed.By splitting the fundamental mode of conventional rectangular or cylindrical DRA into two near-degenerate orthogonal resonant modes, CP is obtained. The proposed antennas are numerically investigated using Finite Element Method (FEM). Parametric study on all antennas is carried out. The results show that the impedance bandwidth (S 11 < −10 dB) of all reported antennas is in the range of 112-140 MHz. Also, the Axial Ratio bandwidth (AR < 3 dB) range of presented antennas is 28-33 MHz. The investigation shows radiation patterns of all proposed antennas are remaining broadside throughout the bandwidth.
