An antenna matching device comprises a directional coupler and, respectively connected, in a prior art manner, to two conjugate ports of the directional coupler, one of which is a high-power port, and the other of which a low-power port, a matching circuit in series with the antenna to be matched, and a matched load. A switching device makes it possible, during the matching phase, to reverse the connections of the aforementioned ports and thus to substitute the directional coupler low-power path for the high-power path in the link between the transmitter and the antenna.
