Abstract
A device for detecting an approach of a part of a user's body and/or of a portable user equipment, housed on board a motor vehicle, including: a near-field communication antenna configured to transmit and receive signals at a high resonant frequency between 3-30 MHz. The antenna includes at least one winding extending continuously in the form of a set of rods such that the rods have a variable capacitance connected to the antenna and the antenna is able to generate a capacitance variation in response to the approach of a part of a user's body; a measurer for measuring, through electromagnetic coupling with the antenna, an impedance variation or a frequency variation of the antenna. The measurer having a series resonant frequency at the selected high resonant frequency and able to detect the approach of a portable user equipment or the approach of a part of the user's body.
