A comparative study of circular microstrip and cylindrical dielectric resonator antennas

The performance of circular microstrip antennas is compared with that of cylindrical dielectric resonator antennas for two operating frequencies (4.1 GHz and 7.0 GHz). The results for the resonant frequency, radiation pattern, antenna directivity, unloaded Q-factor, impedance bandwidth and radiation efficiency are presented, indicating that the performance of the cylindrical dielectric resonator antennas compares well with that of circular microstrip antennas.
