  "textContent": "A device for high-frequency communication and for the inductive charging of an apparatus, including a charging surface, at least one charging antenna emitting a magnetic field at a low frequency and a layer of ferromagnetic material. The device includes at least one communication antenna and a printed circuit board. The communication antenna is in the form of a coil locally surrounding the layer with an axis of symmetry located in a plane parallel to the layer. The material of the layer is selected so as to have, at high frequency, an imaginary part with sufficiently high permeability to generate leaks on a surface of the layer extending perpendicular to the layer, while at the same time maintaining, at low frequency, an imaginary part with sufficiently low permeability to allow inductive charging.",
