Abstract

Automobile vehicle fitted with a dedicated communication system provided with an antenna (4) and enabling exchanges of data signals within a communication area corresponding to the antenna radiation area, forming a volume with a chosen shape and dimensions.

The antenna is an air antenna that forms an elongated loop around a console (3) located on the floor (5) in the automobile vehicle passenger compartment, and that delimits a communication area with a determined shape and extension inside the passenger compartment.

Claims

1. An Automobile vehicle with a passenger compartment on the floor (5) of which there is a longitudinal console (3), extending forwards, and that includes a dedicated low frequency communication system provided with an antenna and that enables exchanges of data signals within a communication area corresponding to the antenna radiation area, forming a volume with a chosen shape and dimensions, characterized in that the antenna (4,4′

) is an antenna forming an elongated loop around the console, along and at the side of which it extends.

2. An automobile vehicle according to claim 1, in which the loop (4B) formed by the antenna (4) of the system extends along the floor in an extension (4A), beyond at least one end of the console (3) to form a communication area that extends beyond the console.

3. A vehicle according to claim 1, in which the antenna (4′

) of the system extends beyond a front end of the console (3′

) and continues along at least one of the dashboard and the instrument panel, inside the passenger compartment to delimit a communication area covering essentially the inside of the passenger compartment and particularly at the front.

4. A vehicle according to claim 1, in which the antenna (4 or 4′

) in the form of said elongated loop is a communication system antenna enabling data exchanges between a recognition device installed in the vehicle and an identification device worn or carried by a user for the purposes of actuating devices installed in the vehicle.
