Receiving device for receiving a magnetic field and for producing electric energy by magnetic induction

A method of manufacturing a receiving device configured to receive a magnetic field and to produce electric energy by magnetic induction, wherein

• a case having a protruding portion is provided for enclosing components of the receiving device to be manufactured,
• at least one coil of an electric line is arranged within the case, wherein the coil comprises an inductance, so that the magnetic field can induce an electric voltage in the coil during operation of the receiving device,
• the coil and its arrangement with in the case are adapted to receive the magnetic field from a receiving side,
• at least one capacitor is provided, which capacitor has a capacitance and is electrically connected to the coil or to at least one of the coils so as to form an electric circuit having a resonance frequency according to the inductance(s) of the coil(s) and to the capacitance(s) of the capacitor(s),
• the at least one capacitor is arranged on a side opposite to a receiving side, in the protruding portion of the case.
