FIELD: measurement equipment.SUBSTANCE: device for measurement of a property of a dielectric material comprises a generator of electromagnetic oscillations, the first isolating element connected by an outlet with an inlet of a phase changer, a transmitting and a receiving antennas, a detector connected with its outlet to a unit of processing of information and an attenuator. To achieve the technical result, the first and second waveguide tees are introduced, as well as the second isolating element. The outlet of the generator of electromagnet oscillations is connected with the first arm of the first waveguide tee, the second arm of which is connected to the inlet of the first isolating element, the outlet of the phase changer via the attenuator is connected with the first arm of the second waveguide tee, the second arm of which is connected to the receiving antenna, the third arm of the second waveguide tee is connected to the inlet of the detector, the third arm of the first waveguide tee via the second isolating element is connected to the transmitting antenna.EFFECT: increased accuracy of measurement.1 dwg |
