Design and Simulation of Compact Wideband Rectangular Dielectric Resonator Antenna for Satellite Applications




Rectangular dielectric resonator antenna, Double Metallic strips, Ku-band, CSTMWS 2013


An objective of the paper is to optimize the parameters, and simulation analysis of compact wideband rectangular dielectric resonator antenna (RDRA). In this paper, a compact wideband, rectangular dielectric resonator antenna is presented using relatively low dielectric constant material and using double microstrip patch. The rectangular DRA is fed with a modified stepped microstrip feed to ensure efficient coupling between the RDRA and the feeder. The performance of the proposed antenna has been significantly improved by loading the RDRA with two narrow conducting metallic strips of suitable widths, which results in dual-resonance excitation and leads to a wider operating bandwidth (16.274-18.200 GHz). The frequency characteristics and radiation performance of the proposed antenna are successfully optimized. Design and simulation results are in excellent agreement.
