Transmission and/or reception device which is intended to be mounted to a vehicle wheel and a housing for one such device

1. A transmission and/or reception device for mounting on a wheel of a vehicle, the device comprising:

a tire information device configured to provide information relating to a tire;

a transmitter/receiver electrically connected to the tire information device;

an antenna electrically connected to the transmitter/receiver for transmitting and/or receiving radio frequency signals; and

a housing configured to house the tire information device and the transmitter/receiver,

wherein the antenna is formed by a cable wound around an outside face of the housing.

2. A device according to claim 1 , wherein the outside face of the housing is shaped to protect the antenna.

3. A device according to claim 1 , wherein the housing is shaped to be positioned on the wheel in such a manner that the wound cable forms a solenoid that is oriented along an ortho-radial axis of the wheel.

4. A device according to claim 1 , wherein the outside face of the housing includes grooves configured to receive the cable.

5. A device according to claim 4 , wherein at least one of the grooves is shaped to receive the cable fully, in such a manner that the cable is protected by the ridges between the grooves against possible contact.

6. A device according to claim 4 , wherein the grooves are formed by spaces between ribs formed on the outside face of the housing.

7. A device according to claim 1 , including an outer protective film covering the antenna formed on the outside face of the housing.

8. A device according to claim 7 , wherein the film comprises a heat-shrink plastic material.

9. A device according to claim 8 , wherein the film comprises at least one of polyethylene and polytetrafluoroethylene (PTFE).

10. A device according to claim 7 , wherein the film comprises at least one of polypropylene, polyphenylene sulphide (PPS), and polyamide.

11. A device according to claim 1 , wherein an outside protecting layer is molded onto the antenna formed on the outside face of the housing.

12. A device according to claim 11 , wherein the molded outside protective layer comprises the same material as the housing.

13. A device according to claim 11 , wherein the molded outside protective layer is obtained by injection molding a thermosetting material.

14. A device according to claim 13 , wherein the thermosetting material comprises at least one of epoxy resin, phenolic resin, polycarbonate, polyurethane, polyamide, vinyl ester, and polyester.

15. A device according to claim 11 , wherein the molded outside protective layer comprises polyphthalamide (PPA).

16. A device according to claim 1 , wherein the tire information device comprises a pressure sensor for measuring the pressure inside a tire mounted on the wheel.

17. A housing for a transmission and/or reception device configured to be mounted to a vehicle wheel, the transmission and/or reception device including an antenna, the housing comprising:

an interior portion for housing the transmission and/or reception device; and

an outside face shaped to support a cable forming the antenna, wherein the outside face is shaped to support the cable wrapped around the housing in a solenoidal arrangement,

wherein the housing is shaped to be positioned on the wheel in such a manner that the wound cable forms a solenoid oriented along an ortho-radial axis of the wheel.

18. A housing according to claim 17 , wherein the outside face of the housing comprises grooves suitable for receiving the cable.

19. A housing according to claim 18 , wherein at least one of the grooves is shaped to receive the cable fully, in such a manner that the cable is protected by the ridges between the grooves against possible contact.

20. A device according to claim 19 , wherein the grooves are formed by spaces between ribs formed on the outside face of the housing.
