Abstract :
Turnable dielectric resonators with dielectric tuning disks in cylindrical and rectangular enclosures are modeled by mode matching method. Tuning properties of TE01 mode such as tuning ranges, spurious mode separation, unloaded quality factors, 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
