Double Back Cylindrical Shaped Dielectric Resonator Antenna with Enhanced Gain and Bandwidth

Abstract

A cylindrical dielectric resonator antenna (DRA) is projected in this paper. This antenna consists of a double back cylindrical shaped DR. A metallic divest is functional at the surface of the DR. The necessary and advanced order cross modes are exhilarated in the antenna geometry because of the explicit structure. The antenna with double back cylindrical DR postulates the quantified axial ratio (AR) of 3dB with bandwidth of 10% in upper band and 25% in lower band. The upper band with 3-dB AR replication can be tweaked in different passbands of 10-dB impedance of the antenna by transmuting the locale and thickness of the metallic divest. Antenna replication can withal be tweaked to achieve the CP operation in triple band.

Keywords: Circular polarization, dielectric resonator antenna, double back cylindrical DRA
