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.

Presence detection sensor for a motor vehicle

Disclosed is an authentication reader intended to be installed on a motor vehicle opening element, the reader including a microcontroller, at least one transmitter, at least one matching circuit and a single antenna, called 'primary' antenna, characterized by a working frequency. The matching circuit includes switching element able to switch the matching circuit between a first mode, in which the matching circuit makes it possible to match the primary antenna to a secondary antenna of an authentication device whose resonant frequency is lower than the working frequency, and a second mode, in which the matching circuit makes it possible to match the primary antenna to a secondary antenna of an authentication device whose resonant frequency is higher than the working frequency.
