要約

Possibilities of the resonance frequency fine tuning for the H111 oscillation of the waveguidedielectric resonator (WDR) with the short-circuit plunger have been analyzed. The eigen frequencies (f) and Q-factors (Q) of the investigated oscillation in the WDR on the evanescent waveguide have been computed. The resonator models were made for the centimeter and millimeter wavebands and values dependencies f and Q as a function of short-circuit plunger have been investigated experimentally. The comparison of the computed dependencies with the control measurements and measurements with short-circuit plunger has been made. The influence of the clearance between the short-circuit and the evanescent waveguide wall on the tuning characteristics of the eigen frequencies and Q-factors for the investigated oscillation was estimated.
