Abstract
A device for a vehicle access control system, includes: a main electrode for carrying out a capacitive-type approach detection; and a transmitting and receiving antenna which is formed by a coil and is configured to transmit and receive a radiofrequency signal in order to identify a user. One turn of the coil includes: a first portion which delimits a region inside of which the main electrode is located; a second portion is offset relative to the main electrode, and at least one notch extends along one edge of the main electrode and connects the first portion and the second portion together. Each notch including two sections which are parallel to one another and connected together by a portion of the turn located at the bottom of the notch. It is thus possible to obtain a large antenna, which at the same time effectively performs a guard ring function for the main electrode.
