FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, particularly to flat inductance coils. Flat inductance coil comprises a multilayer winding of the excitation coil, each layer of which is made on the basis of a printed-circuit board, and a magnetic compensator of magnetically soft material. Magnetic compensator includes two walls located on both sides of winding in plane of inductance coil.
EFFECT: technical result consists in simplifying the design and reducing the size of the coil, as well as high Q-factor of the inductance coil when operating at high operating frequencies.
