<p>The invention relates to an identification device (1) which is intended for a motor vehicle comprising a hands-free access and/or engine start system. The inventive device comprises a main antenna (3), an electronic antenna control circuit and electric connection means (4, 8, 9) which connect the electronic circuit (2) to the main antenna (3). According to the invention, the electric connection means (4, 8, 9) comprise at least one electric wire (8, 9) which is arranged such as to form a loop at at least one part (7), said loop generating a local magnetic field and, thereby, forming a secondary antenna. The secondary antenna is located inside the vehicle and, in this way, ensures coverage of any zones that are not covered by the main antenna.</p> |
