Abstract
Radiation efficiency (due to conduction and dielectric losses) of dielectric resonator antennas has been measured. Results show that for dielectric resonators placed directly on a metallic plane, the conduction losses are quite small. A radiation efficiency of >98% has been measured for dielectric resonator antennas operated in the dominant hybrid (HE/sub 11/spl delta//) mode. Theoretical considerations show scope of further improvement in the radiation efficiency by choosing optimum resonator parameters.Keywords
