Circular Polarized Cylindrical Dielectric Resonator Antenna Using a Single Probe Feed

摘要：

In this paper two novel cylindrical dielectric resonator antennas (CDRAs) providing circular polarization (CP) using a single probe feed are proposed. By splitting the fundamental mode of cylindrical DR into two near-degenerate orthogonal resonant modes,CP is obtained. The proposed antennas are numerically investigated using High Frequency Structure Simulator (HFSS) based on Finite Element Method (FEM).Parametric study on both antennas is carried out. The results show that at least 50 MHz of impedance bandwidth (S11 < -10dB)at resonate frequency of 1.8 GHz is obtained. Also minimum Axial Ratio (AR) bandwidth of 14 MHz is achieved. The investigation shows radiation patterns of the proposed antennas are remaining broadside throughout the bandwidth.
