Abstract :
Possibility of the essential increase of the eigen Q-factor of the waveguide-dielectric resonator (WDR) on the fundamental asymmetrical mode of the magnetic type for the frequency tuning with help of resonance short-circuit plunger has been shown. For the WDR on the basis of a circular evanescent waveguide section with Teflon dielectric in 8-mm band the Q-factor of the resonator exceeding 2400 was obtained for all turn frequency band which is about 10%.
