Resonator With Liquid Crystal And Gas Bubble

Abstract

A dielectric element for a resonator and a corresponding resonator are described. The dielectric element has a first chamber and a second chamber, which are fluidically connected to one another by a connecting channel. A liquid crystal is contained in the first chamber, a gas is contained in the second chamber. Changes in the volume of the liquid crystal can be compensated by a change in the volume of the gas, because the liquid crystal can move in the connecting channel. Consequently, such a resonator can be exposed to greatly fluctuating temperature ranges without requiring any further compensation for temperature-induced changes in the volume of the liquid crystal. The dielectric element can also be hermetically closed to complete the production process.
