<p>The invention relates to a signal transmission/reception device (DER) which can cooperate with an antenna device (A) capable of emitting a magnetic field. The invention is characterised in that the device (DER) comprises the following elements for transmission, namely: a power stage (P) for sending a symmetrical square-wave voltage signal (U0) to the input of the antenna device (A) in order to supply same with a current that can be used to generate the emitted magnetic field; and a current measuring stage (C) for measuring the current circulating in the antenna device (A). The invention is suitable for motor vehicles.</p>
