SHF DETECTOR Russian patent published in 2012 - IPC H01P7/06 

FIELD: electricity.

SUBSTANCE: SHF detector contains a section of a rectangular feeding waveguide with a short circuitor at one end; installed inside the wave guide is a detector SHF diode of cartridge type; the diode first electrode fixation is ensured via a cylindrical metal slug affixed (via threaded connection) to the wave guide broad wall through a hole in the broad wall; the depth of the slug lower part penetration into the waveguide is limited by a jam nut; the diode first electrode is fixed in the first blind hole on the slug lower part side the axis whereof is shifted diametrically parallel to the metal slug rotation axis; arranged in the metal slug is a second through hole the axis whereof is shifted diametrically parallel to the slug axis; installed in the second hole is a dielectric slug wherethrough a metal rod output is introduced into the wave guide; the diode second electrode is connected (via an electric conductor) to the lower end of the rod output forming an inductive loop of the diode to the waveguide coupling.

EFFECT: considerable increase of SHF detector sensitivity.
