A Low Profile, High Permittivity Cylindrical Dielectric Resonator Antenna for Microwave Communication

Abstract

A low profile dielectric resonator antenna (DRA) using a high permittivity medium was fabricated. The DRA was excited by aperture coupling. The DRA showed an impedance bandwidth of 3.68 % at 3.53 GHz along with a gain of 2.8 dBi. The nature of circular polarization can be revealed from the radiation pattern
