Resonating microwave cavity with double dielectric resonator and tunable resonance frequency.

摘要

Resonant microwave cavity with double dielectric resonator and tunable resonance frequency wherein the primary dielectric resonator is sealed in a quartz support which holds up a secondary dielectric resonator and keeps it at a fixed distance from the primary resonator. Tuning is achieved by a metal screw with adjustable distance from the secondary resonator. There is obtained a strong structure which minimizes the negative effects of mechanical vibrations on the resonance frequency whose adjustment is linear with the distance of the screw from the resonator. In addition the Q-factor of the cavity remains constant with the variation of the tuning frequency. <IMAGE>
