DEVICE TO MEASURE PARAMETERS OF DIELECTRICS AT ULTRAHIGH FREQUENCIES Russian patent published in 2015 - IPC G01R27/26 

FIELD: measurement equipment.

SUBSTANCE: device comprises a microwave waveguide, a resonator with a cylindrical part limited at one side by the end wall of the microwave waveguide, and at the other side with a shorting piston with the ability of axial displacement inside the resonator, a piston displacement mechanism and a unit of radio measurement equipment. At the same time the microwave waveguide, the resonator cylinder and the displacement mechanism are installed in a single cylindrical body. The resonator cylinder is installed inside the body with the possibility of axial displacement and is equipped with clamps for fixation in the body, and the piston by means of the stem is fixed on the platform of the axial displacement module with a drive from a servomotor combined with the metre of linear displacement. The servometer is equipped with a system of automatic control connected with a radiometric block of fixation of resonant position of the piston.

EFFECT: increased accuracy of measurement of dielectric parameters and automation of a measurement process.
