ULTRA-WIDEBAND MAGNETIC FIELD INTENSITY CONVERTER Russian patent published in 2019 - IPC H01Q7/08 

FIELD: radio equipment.

SUBSTANCE: invention relates to radio receiving equipment and can be used in radio measurements, radio direction finding, radio navigation in frequency bands ELF – UHF. Transducer comprises rectilinear ferrite core with winding coaxial with surrounding screened dielectric case. Screen contains two identical longitudinal parts separated by two identical slits parallel to the device axis and diametrically opposite to it relative to it, and the first and the second end parts, along the conjugation lines electrically connected to longitudinal parts of the screen. Each end part of the electric shield consists of two equal parts separated by end cutouts electrically connected to each other in central sections of the corresponding end part of the screen. Slots and end cutouts of electric screen are interconnected at their ends. Axes of symmetry of slits and end cutouts of electric shield lie in one plane with axis of the device. Ends of two winding conductors are electrically connected to each other on both sides along axisymmetric lines lying along end faces of ferrite core, and axial jumpers – with centre of first end part of electric shield and with internal conductor of output radio frequency coaxial connector, which housing is by closed circuit electrically connected to central section of second end part of electric screen. Internal load is connected in parallel to output radio-frequency coaxial connector. Winding is made with axial symmetry of the second order, other structural components are made mirror-like relative to orthogonal planes crossing along the device axis.

EFFECT: technical result consists in expansion of frequency range and increase in frequency coverage overlapping ratio.
