Abstract

In this paper, a compact broadband, low-profile rectangular dielectric resonator antenna (RDRA) is presented using relatively low dielectric constant material. The rectangular DRA is fed with a modified stepped microstrip feed to ensure efficient coupling between the RDR and the feeder. The performance of the proposed antenna has been significantly improved by loading the RDR with two narrow conducting metallic strips of suitable widths, which results in dual-resonance excitation and leads to a wider operating bandwidth (up to 24 %). Parametric investigations of some geometrical variables have been carried out. The frequency characteristics and radiation performance of the proposed antenna are successfully optimized and experimentally verified. Measurements and simulation results are in excellent agreement.
