Method of emitting data by inductive coupling, comprising the steps consisting in: extracting an antenna signal (AS) from an antenna circuit, extracting from the antenna signal a first periodic signal (CKe), producing a second periodic signal (CKs) by means of a synchronous oscillator (SO, OSC1), placing the oscillator in a mode of free oscillation and applying the second periodic signal (CKs) to the antenna circuit, modifying (DCT) the impedance of the antenna circuit, re-establishing the amplitude of the antenna signal, then resynchronizing the oscillator to the first periodic signal (CKe). |
