Circularly polarized dielectric resonator antenna

Abstract

A new structure of a circularly polarized dielectric antenna fed by a single coaxial probe is proposed. The configuration includes four identical holes enclosed in a cylindrical resonator. The structure offers a bandwidth of 5% and a good purity of polarization. The effects of altering geometrical parameters on antenna behavior are presented. © 2005 Wiley Periodicals, Inc.
