Theoretical & Experimental Investigation of a Probe-fed Rectangular Dielectric Resonator Antennas
Year
: 2000
Abstract: 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.
