Abstract

The invention relates to an arrangement with a transponder (2) and a metal component (1) provided for the transponder (2). An antenna for the transponder (2) is formed by a recess (3) in the metal component (1).

Claims

1. Arrangement with a transponder (2) and a metal component (1) allocated to the transponder (2), characterised in that an aerial for the transponder (2) is formed by means of a recess (3) in the metal component (1).

2. Arrangement according to claim 1, characterised by a cover (17) allocated to the recess (3).

3. Arrangement according to claim 2, characterised by a cavity (23) which is enclosed by the cover (17) and the metal component (1).

4. Arrangement according to claim 2, characterised in that the cover (17) comprises one or a combination of the following materials:

a metallic material and a non-metallic material.

5. Arrangement according to claim 3, characterised in that the cavity (23) is at least partially filled with a dielectric material.

6. Arrangement according to claim 5, characterised in that the dielectric material in the cavity (23) is formed from the same material as the cover (17).

7. Arrangement according to claim 2, characterised in that the cover and/or the dielectric material in the cavity (23) are/is formed as a screening.

8. Arrangement according to claim 1, characterised in that the aerial formed by means of the recess (3) in the metal component (1) is executed as a high frequency aerial and the transponder (2) is executed as a high frequency transponder.

9. Arrangement according to claim 1, characterised in that the recess (3) is formed at least partially as a breakthrough (5) in the metal component (1).

10. Arrangement according to claim 1, characterised in that the transponder (2) is secured to the metal component (1).

11. Arrangement according to claim 1, characterised in that the transponder (2) at least partially covers the recess (3).

12. Arrangement according to claim 1, characterised in that the recess (3) in the metal component (1) has an extended form.

13. Arrangement according to claim 1, characterised in that the recess (3) in the metal component (1) has the form of a ring segment.

14. Arrangement according to claim 1, characterised in that a connection (6) for transmitting signals is formed between the transponder (2) and the aerial formed by means of the recess (3) in the metal component (1).

15. Arrangement according to claim 14, characterised in that the connection (6) comprises a capacitive and/or an inductive coupling.

16. Arrangement according to claim 14, characterised in that the connection (6) is formed by means of contacts (7).

17. Arrangement according to any one of the claims 14, characterised in that the connection (6) comprises a coaxial cable (13).

18. Arrangement according to claim 1, characterised in that the transponder (2) is at least partially arranged in the recess (3) in the metal component (1).

19. Arrangement according to claim 18, characterised in that the transponder (2) is submerged fully in the recess (3) in the metal component (1).

20. Arrangement according to claim 1, characterised in that the recess (3) in the metal component (1) is partially or fully filled with a non-conductive material.

21. Arrangement according to claim 20, characterised in that the recess (3) in the metal component (1) is filled up with the non-conductive material, at least up to a thickness which is one fiftieth as large as the wavelength of the electromagnetic signals for which the aerial, formed by the recess (3) in the metal component (1), is designed.

22. Arrangement according to claim 1, characterised in that the metal component (1) with the recess (3) is part of a pipe-shaped component (15).

23. Arrangement according to claim 22, characterised in that the recess (3) is formed along the longitudinal axis of the pipe-shaped component (15).

24. Arrangement according to claim 1, characterised in that the metal component (1) with the recess (3) is part of a container.

25. Arrangement according to claim 24, characterised in that the container comprises a grid box (19).

26. Arrangement according to claim 24, characterised in that the container is a beverage barrel (20).

27. Arrangement according to claim 1, characterised in that the metal component (1) with the recess (3) is part of a motor vehicle registration plate (18).

28. Arrangement according to claim 1, characterised in that the transponder (2) comprises a further aerial.
