Abstract :
Tunable dielectric resonators with dielectric tuning disks in cylindrical enclosures are modeled by mode matching method. Tuning properties of TE/sub 01/ mode such as tuning ranges, spurious mode separation, unloaded quality factors and couplings, etc., are investigated for both rod- and ring-type dielectric resonators. Wide tuning ranges are obtained while other properties of resonators are maintained over the tuning ranges.
