<p>The invention relates to an antenna transmission method and device for motor vehicles. The inventive device is intended to be fixed to a vehicle having a determined direction (4) of movement. According to the invention, at least one channel is formed, which corresponds to the transmission or reception of the signal and which is limited to an angular section (9j) associated with the path direction of the signal, of less than 360 DEG . The channel is connected to a means which is used to apply a frequency correction thereto. The aforementioned frequency correction is dependent on the value of the speed at which the vehicle is moving in the direction (4) of movement and on an angular value included in the channel section (9j), such as to reduce the frequency offset of the channel owing to the Doppler effect acting on the signal.</p> |
