Abstract
Radiation efficiency (due to conduction and dielectric losses) of diel ectric resonator antennas has been measured. Results show that for die lectric resonators placed directly on a metallic plane, the conduction losses are quite small. A radiation efficiency of > 98% has been meas ured for dielectric resonantor antennas operated in the dominant hybri d (HE11delta) mode. Theoretical considerations show scope of further i mprovement in the radiation efficiency by choosing optimum resonator p arameters.
