Abstract

An apparatus, a tire, a transmitting and/or receiving device and a system for the wireless transmission of data are proposed, the apparatus being connected to a rotatable part, the part having a metal belt, the apparatus having an antenna device which is provided in a manner that it is able to be coupled inductively and/or capacitively to the metal belt.

Claims

1. An apparatus for at least one of transmitting and receiving data, the apparatus being connected to a rotatable part having a metal belt, the apparatus comprising:

an antenna device that is able to be coupled at least one of inductively and capacitively to the metal belt;

wherein the apparatus permits an energy supply by a hop between the apparatus and the metal belt, and a transmission power of the hop is low.

2. The apparatus as recited in claim 1, wherein:

the metal belt includes a steel belt.

3. The apparatus as recited in claim 1, wherein:

the rotatable part includes a tire of a vehicle.

4. The apparatus as recited in claim 1, further comprising:

a first capacitor for storing electrical energy.

5. The apparatus as recited in claim 4, further comprising:

a second capacitor; and

a resistor.

6. The apparatus as recited in claim 1, further comprising:

a diode.

7. The apparatus as recited in claim 6, wherein:

the diode includes a varactor.

11. The apparatus as recited in claim 1, further comprising:

a data-preparation unit.

12. The apparatus as recited in claim 1, further comprising:

a sensor arrangement.

13. The apparatus as recited in claim 1, further comprising:

a transmitting/receiving unit.

14. The apparatus as recited in claim 1, wherein:

a magnetic field of the hop penetrates the metal belt.

15. The apparatus as recited in claim 1, wherein:

the metal belt includes one of an intermediate antenna and an auxiliary antenna.

16. The apparatus as recited in claim 1, wherein:

the rotatable part includes a second antenna arranged adjacent to the metal belt.

17. The apparatus as recited in claim 16, wherein:

the second antenna includes a wire.

18. The apparatus as recited in claim 1, wherein:

energy for data transmission is drawn from a direct surrounding field of the apparatus.

19. The apparatus as recited in claim 1, wherein:

the transmission power of the hop is low so that a screening of radio waves by the metal belt is small.

8. A tire for a vehicle, comprising:

an apparatus for at least one of transmitting and receiving data, the apparatus being connected to a rotatable part having a metal belt and the apparatus including an antenna device that is able to be coupled at least one of inductively and capacitively to the metal belt;

wherein the apparatus permits an energy supply by a hop between the apparatus and the metal belt, and a transmission power of the hop is low.

20. The tire as recited in claim 8, wherein:

the transmission power of the hop is low so that a screening of radio waves by the metal belt is small.

9. A device for at least one of transmitting and receiving, comprising:

an arrangement for cooperating with an apparatus for at least one of transmitting and receiving data, the apparatus being connected to a rotatable part having a metal belt and the apparatus including an antenna device that is able to be coupled at least one of inductively and capacitively to the metal belt;

wherein the apparatus permits an energy supply by a hop between the apparatus and the metal belt, and a transmission power of the hop is.

21. The device as recited in claim 9, wherein:

the transmission power of the hop is low so that a screening of radio waves by the metal belt is small.

10. A system, comprising:

an arrangement for providing a wireless transmission of data between an apparatus and a device for at least one of transmitting and receiving device, the apparatus being for at least one of transmitting and receiving data, the apparatus being connected to a rotatable part having a metal belt and the apparatus including an antenna device that is able to be coupled at least one of inductively and capacitively to the metal belt;

wherein the apparatus permits an energy supply by a hop between the apparatus and the metal belt, and a transmission power of the hop is low.

22. The system as recited in claim 10, wherein:

the transmission power of the hop is low so that a screening of radio waves by the metal belt is small.
