Realization of Rectangular Dielectric Resonator Antenna for Broadband Applications

Abstract

Due to the fast growth of technology, the demand for wireless mobile communications has led to the development of antennas that are low profile and small in size. Therefore, in this presentation, a novel broadband, low-profile dielectric resonator antenna using relatively low dielectric constant substrate material has been presented. A broadband low profile dielectric resonator antenna that uses a relatively low dielectric constant substrate has been proposed. A stepped microstrip feeding mechanism has been analyzed to achieve efficient coupling over a wide bandwidth. The DRA has been made from inexpensive widely available substrate material. Furthermore, methods for size reduction of the proposed antenna using metallic patches have been investigated. Simulations as well as experimental results are also presented using Comsol software.
