Abstract
Disclosed is a system for detecting approach and/or contact of a user and Ultra High Frequency communication with a portable user apparatus, intended to be embedded on board an automotive vehicle, the system including: a device for detecting approach and/or contact, including a sensor for detecting approach and/or contact and an electronic control unit; a conducting metal surface, suitable for the conduction of electric charges; and a communication device, including an Ultra High Frequency antenna emitting an electromagnetic field at an Ultra High Frequency wavelength, and a management unit for managing the emission and reception of data of the antenna. The conducting metal surface takes the form of a continuous path including a plurality of meanders spread over a length at least equal to:=λ/6wherein L is a total length of the meanders, and λ is a wavelength of the Ultra High Frequency antenna.
