DEVICE FOR MEASURING THE INHERENT QUALITY OF A DIELECTRIC RESONATOR Russian patent published in 2021 - IPC G01R27/26 H01P7/06 H01P7/10 

FIELD: microwave technology.

SUBSTANCE: invention relates to microwave technology. A device for measuring the intrinsic Q-factor of a dielectric resonator contains a waveguide section connected to a volume metal resonator. The resonator is made in the form of a parallelepiped with a rectangular cross section. An open dielectric resonator with the lowest H-type of oscillation with a resonant frequency equal to the resonant frequency of the volumetric metal resonator is located in the center of the cross-section and longitudinal dimension of the volumetric metal resonator. An open dielectric resonator is fixed on a dielectric rod, the axis of which is parallel to the plane of the wide wall of the open dielectric resonator. The dielectric rod is installed so that it can rotate around the axis of the rod. The coupling element of a section of a waveguide with a rectangular cross-section with a volumetric metal resonator is made in the common wall of a section of a waveguide with a rectangular cross-section and a volumetric metal resonator at a point spaced from the center of the volumetric metal resonator in the longitudinal direction by half the wavelength at the resonant frequency, and the second coupling element is made in a common wall at a point spaced from the coupling element in the longitudinal direction by a quarter of the wavelength at the resonant frequency of the resonator.

EFFECT: simplification of the measurement process.
