Cavity resonator having an adjustable resonance frequency

摘要

The aim of the invention is to provide a cavity resonator that has a great variable frequency area of a resonance frequency and is provided with good quality. Such a cavity resonator is provided with a round cross-section. The H11n in wave mode acting as the resonance wave mode exists in said resonator which is separated into two components with regard to the cross-sectional plane ( 5 ) thereof. The two cavity components ( 1, 2 ) can be displaced against each other in the direction of the common longitudinal axis ( 7 ) thereof.
