| Abstract | In this paper a linear circular polarized (CP) Dielectric Resonator Antenna (DRA) array, consist of 3 elements DRA using elliptical resonators, positioned on top of a metallic ground plane exciting through narrow slots is numerically investigated. A Dielectric Image Line (DIL) placed at the back side of the plane is used to excite slots. Antenna characteristics for a single element and linear array including return loss, radiation patterns and antenna gain are presented. To reduce the backward radiation a reflector is placed at the back side of structures. Results show that 5.3% bandwidth is obtained for 3dB Axial Ratio (AR) at 10 GHz.
