Abstract
Disclosed is a detection sensor for detecting the presence of an item of user equipment through near-field communication for a motor vehicle, the sensor including an antenna, an impedance matcher, a driver module for driving the antenna and a microcontroller, which is configured to control the driver module, the impedance matcher being able to match the output impedance of the driver module to the impedance of the antenna while amplifying the power supplied by the driver module. The sensor includes a resistive module, mounted between the driver module and the impedance matcher, configured to stabilize the value of the input power of the impedance matcher.
