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. © 2003 Wiley Periodicals, Inc.
