Abstract
A tunable resonator is provided. The resonator includes a housing having a cavity. A resonator body is disposed adjacent to a first surface within the cavity. A gap is formed between the resonator body and the first surface. The resonator is tuned by controlling the size of the gap.
Claims21
A resonator, comprising:
- a housing having a cavity and constructed of a non-dielectric material;
- an opening in the housing;
- a resonator body disposed in the cavity and covered the opening in the housing;
- and
- a movable tuning plate, disposed in the opening of the housing formed by the non-dielectric material, the plate adapted to be moved within the opening to control a distance between the plate and the resonator body to tune a resonant frequency of the resonator.
