Abstract
in this paper, a compact broadband, low-profile rectangular dielectric resonator antenna (RDRA) is proposed using relatively low dielectric constant substrate material (Rogers RT/Duroid 3010 er = 10.2) and developed for wireless communication applications. The rectangular DRA is fed with a modified stepped Microstrip feed to ensure efficient coupling between the RDRA and the feeder. Broadband operation is achieved by loading the rectangular dielectric resonator antenna with conducting metallic strip which results in a new resonance beside the antenna operating frequency. The performance of the proposed antenna has been significantly improved by loading the RDRA with two narrow conducting metallic strips of suitable lengths, which results in dual-resonance excitation and leads to a wider operating bandwidth (up to 23.75 %). The frequency characteristics and radiation performance of the proposed antenna are successfully optimized using numerical experimentation techniques. The antenna size reduction is demonstrated while maintaining a reasonable bandwidth. Simulations results based on a 3D full-wave electromagnetic simulator are presented in the paper.
