Abstract
A device () for charging a portable element () having a receiving antenna (Ar) for charging by induction, the charging device () includes: a charging surface (Sc); a plurality of emitting antennas (A, A); a layer of ferromagnetic material () placed beneath the plurality of emitting antennas (A, A); an electronic circuit; a plurality of resonators (R, R. . . Ri): having a resonance frequency substantially equal to the emission frequency of the antennas, placed between the plurality of antennas and the charging surface, and suitable, when they are activated, for reflecting the magnetic field (B) emitted by the antennas, and connected to the electronic circuit in order to be deactivated individually, according to a criterion of positioning of the receiving antenna relative to the resonators. An associated charging method is also described.
