Abstract

A wideband circularly polarized (CP) conical dielectric resonator antennas (DRA) is investigated in this paper. The DRA is excited by a single 45 inclined slot fed by a microstrip feed line. The inclination of the slot creates a circular polarization of the radiated wave. The gain of the dielectric resonator antenna varies between 4.8 and 7.2 dBi. This study analyze also à parametric study on the effect size of dielectric resonator on bandwidth and coefficient of reflection. The reflection coefficient, AR, radiation pattern, and antenna gain of are studied, and reasonable agreement between the measured and simulated results is observed.
