in this paper a novel dielectric resonator antenna (DRA) with circular polarization and a single probe feed is proposed. The antenna structure includes a Dielectric Resonator (DR) which is chopped thorough the y axis diameter and fed by single coaxial line. Circular polarization (CP) is obtained by exciting two orthogonal modes of a cylindrical DR in phase quadrature. Exciting two orthogonal modes of a cylindrical DR is the results of DRA cutting. The proposed antenna provides axial ratio of less than 3dB over a *** MHz (*** %) bandwidth with a minimum value of *** dB in this range. The impedance bandwidth of the antenna is **** MHz (*** %) which is *** times greater than conventional cylindrical dielectric resonator antenna. Comparison between simulations, based on HFSS software and measurements are provided.
