Abstract: 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 situated 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.

Abstract: A device for the inductive recharging of an electronic element of the mobile-phone or digital tablet type having at least one receiving antenna. The device having an exterior face intended to support the electronic element, a stage of planar shape being able to move inside the device and bearing at least one emitting antenna intended to be aligned with, and in close proximity to, the at least one receiving antenna, the mobile stage being actuated by a motorized actuating mechanism. The actuating mechanism includes a single motor coupled to a main drive element that renders the stage mobile in a plane parallel to the exterior face of the device, the main drive element being circular in shape, and the motor meshing with a periphery of the main drive element and driving the main drive element in rotation.
