Abstract
The disclosure relates to a device for identifying a motor vehicle comprising an identification unit carried by the user, a central onboard console (1) for verifying the user's identification data via an electromagnetic wave communication, through a resonant circuit having at least one tuning capacitor (13) and at least one coil transmitting/receiving (12) identification data; and at least one support module (10) comprising said transmission/reception coil and fitted at the vehicle door; said support module and said central console are spaced apart from each other and connected by electrical connection means; the invention is characterized in that the resonant circuit tuning capacitor is fitted in said support module (10) to limit parasitic radiation from the resonant circuit.

Device for identifying an automobile vehicle comprising an identification unit carried by the user, a central onboard console (1) for verifying the user's identification data via electromagnetic wave communication, through a resonant circuit (2, 12, 13) having at least one tuning capacitor (13) and at least one coil (12) transmitting/receiving identification data;
- and at least one support module (10) comprising said transmission/reception coil (12) and fitted at the vehicle door;
- said support module (10) and said central console (1) being spaced apart from each other and connected by electrical connection means (20-24;
- 32-34), wherein said resonant circuit tuning capacitor (13) is fitted with said transmission/reception coil (12) in said support module (10) to limit parasitic radiation from said resonant circuit.
