FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering. Receiving device (1) for receiving a magnetic field and for producing electric energy by magnetic induction comprises at least one coil (33, 35, 37) of an electric line. Magnetic field induces an electric voltage in coil (33, 35, 37) during operation. Coil (33, 35, 37) has an inductance. Receiving device (1) and coil (33, 35, 37) are adapted to receive the magnetic field from a receiving side. Receiving device (1) comprises case (2, 3) enclosing at least one coil (33, 35, 37) and further components of receiving device (1), at least one capacitor (115) having a capacitance. Capacitor (115) is electrically connected to the coil or to at least one of coils (33, 35, 37), so as to form electric circuit (111), having a resonance frequency according to the inductance of coil (33, 35, 37) and to the capacitance of capacitor (115). At least one capacitor (115) is arranged on a side opposite to the receiving side, in protruding portion (5) of case (2, 3).
EFFECT: reception of a magnetic field.
