APPARATUS FOR MEASURING INTRINSIC QUALITY FACTOR OF DIELECTRIC RESONATOR Russian patent published in 2021 - IPC G01R27/26 

FIELD: electrical engineering.

SUBSTANCE: invention relates to ultra high frequency equipment and is intended for measuring selective properties of high-quality miniature open dielectric resonators. The apparatus comprises a waveguide section 1 with a rectangular cross-section, electromagnetically connected with a volumetric metal resonator 2 via a connecting element 3, and an open dielectric resonator 4 with the lowest H-type oscillation with a resonant frequency equal to the resonant frequency of the volumetric metal resonator 2, placed in the volumetric metal resonator. The volumetric metal resonator 2 is made in form of a parallelepiped with a rectangular cross-section identical to the cross-section of the waveguide section 1 and with a length L equal to the wavelength λ in the waveguide at the resonant frequency of the volumetric metal resonator 2. The volumetric metal resonator 2 is installed longitudinally at the end of the waveguide section 1 with a rectangular cross-section and is separated therefrom by a metal wall 5 attached at the end, configured to rotate around the longitudinal axis of the waveguide section 1 with a rectangular cross-section, with the connecting element 3 in form of a hole in the wall 5 in form of a slot parallel to the wide wall 6 of the resonator 2. The resonator 4 is placed in the centre of the cross-section and the longitudinal dimension of the volumetric metal resonator 2. The wide wall 7 of the open dielectric resonator 4 is perpendicular to the plane of the wide wall 6 of the resonator 2. The open dielectric resonator 4 is fixed on a dielectric rod 8 the axis whereof is parallel to the plane of the wide wall 8 of the open dielectric resonator 4 and wherein said rod is installed in the hole 9 in the wide wall 6 of the volumetric metal resonator 2, configured for said resonator to rotate around the axis of the dielectric rod 8.

EFFECT: simplification of the process of adjustment of measuring equipment with increased accuracy of measuring the intrinsic quality factor of an open dielectric resonator.
