Study of dielectric resonator antennas its applications for wireless communications

Abstract

The dielectric resonator has high conducting boundary, which can radiate, and so it becomes an antenna, named Dielectric Resonator Antennas (DRAs). DRAs consist of dielectric materials in its radiating patch also called as dielectric resonators (DRs) on one side of the substrate .which has a ground plane on the other side. DRAs have several qualities, including high radiation efficiency, flexible feed arrangement, simple geometry and compactness. There are wide applications of DRAs and it can be designed for the communication, high impedance, low profile, high gain.
