Abstract
The data and/or command signal transmission device includes a first signal generator connected to a first antenna arrangement, a second signal generator connected to a second antenna arrangement, a third signal generator connected to a third antenna arrangement, and a synchronization circuit. The synchronization circuit performs data amplitude modulation by combining the signals transmitted by the antenna arrangements. The signals transmitted by the first and third antenna arrangements are in-phase in a first stable modulation state and 180° out of phase in a second stable modulation state. In a modulation state transition phase, the first and third signals delivered by the first and third generators are at a different frequency from the carrier frequency of the signals delivered by the second generator. The resonance frequency of the first and third antenna arrangements is also adapted in the transition phase.
