要約

Resonance structures of the waveguide-dielectric type are the matter for the scientific investigations contributing to the development of the resonators of new modifications with the improved parameters. The waveguide-dielectric resonators (WDR) with the short-circuit plunger have widespread application due to the wide band of the frequency tuning. But the eigen Q-factors of the oscillations in these resonators are lower than calculated ones because of the unreliable contact between the plunger and the waveguide. In this paper the use of the resonance short-circuit plunger in the WDR for the Q-factor increase of the resonance oscillations are substantiated. The characteristics of the H111-mode in the WDR for 3-cm band with resonance short-circuit plunger and the simple design short-circuit plunger are investigated. The resonance characteristics of the eigen frequency and Q-factor for the H-fundamental mode for the two models of the WDR as a function of short-circuit plunger location are compared. The Q-factors obtained with the help of resonance short-circuit plunger agree closely with calculated values.
