Abstract :
The paper discusses quality factor of shielded cylindrical metal-dielectric resonator tuned by means of variable air gap between resonator´s base and shield. Mode matching technique was used to estimate resonator´s quality factor taking into account dielectric and metal losses. It was shown that metal and dielectric losses decrease in case of the air gap inclusion.
