Wideband dielectric resonator-loaded suspended microstrip patch antennas

摘要

Experimental investigations of rectangular and circular suspended microstrip patch antennas with dielectric resonator loading at X-band are reported. With loading, enhanced impedance bandwidth to about 18% is achieved in a single circular patch as compared to 13% for a single rectangular patch. In both cases, with loading, there is practically no change in the respective 3-dB beam widths of the radiation patterns in E- and H-planes.
