Abstract	In this paper, a compact broadband, low profile rectangular dielectric resonator antenna (RDRA) is presented. The RDRA is fed with a modified stepped microstrip feed to ensure efficient coupling between the RDR and feeder. Impedance improvement and broadband operation is achieved by loading the RDR with conducting metallic strip of suitable width, which results in a new resonance closes to the antenna operating frequency. The performance of the proposed antenna has been significantly improved and leads to a wider operating bandwidth (up to 22 %). Parametric investigations for different geometrical parameters have been carried out. The frequency characteristics and radiation performance of the proposed antenna are successfully optimized with numerical experimentation techniques and experimentally verified. Measurements and simulation results based on a 3D full-wave EM simulator are in excellent agreement.
