NEAR-FIELD COMMUNICATION DEVICE INTENDED TO BE INTEGRATED IN A MOTOR VEHICLE

A near-field communication device intended to be integrated in a motor vehicle and including: a printed circuit board having at least four functional layers made of electrically conductive material, separated from each other by insulating layers made of dielectric material; a near-field communication antenna, formed by four concentric turns integrated on the printed circuit board; and at least one electronic power supply and signal-processing circuit connected to the antenna and integrated on the printed circuit board. The four turns are distributed over only two adjacent functional layers, this reducing a drift in the inductance of the antenna, from one device to the other.
