Abstract: 
A Rectangular Dielectric Resonator Antenna (RDRA) is theoretically analyzed using the Conventional Dielectric Waveguide Model (CDWM), numerically simulated using the High Frequency Structure Simulator (HFSS) based on the Finite Element Method (FEM) software package and experimentally investigated with the consideration of the fundamental mode TE111. Antenna parameters under investigation include resonance frequency, radiation patterns, directivity, Q-factor, impedance bandwidth and cross polarization level. The results for a specific resonator are presented and compared with those obtained by experiments. It is concluded that the CDWM can be used for a first order estimation of the antenna parameters, but more accurate results can be obtained using the FEM for radiation patterns.
