Abstract

The invention relates to a transponder unit (10), in particular for transponder cards, identification documents or suchlike, having at least one chip (15) and at least one antenna (11), wherein the antenna is formed from a metal conductor which is arranged on an antenna substrate (14) and is permanently connected to the latter, and wherein said conductor is provided with a structure device which is integrally connected to the conductor and is intended to form a composite conductor (12) such that the composite conductor has a higher tensile stress or a higher elongation break than the conductor.

Claims

1. A transponder unit comprising:

a transponder unit for transponder cards, identification documents or suchlike having at least one chip and at least one antenna, wherein said antenna is formed from a metal conductor, which is arranged on an antenna substrate and is permanently connected to the latter,

wherein said conductor is provided with a structure device which is integrally connected to said conductor and is operable to form a composite conductor such that said composite conductor has a higher tensile stress than said conductor.

3. The transponder unit according to claim 1, wherein

said structure device of said conductor substantially consists of at least one metal material.

4. The transponder unit according to claim 1, wherein

said structure device of said conductor is at least an alloy component of said conductor.

5. The transponder unit according to claim 1, wherein

said structure device of said conductor is at least a cover layer of said conductor.

6. The transponder unit according to claim 5,

wherein said cover layer of said conductor is formed by diffusion.

7. The transponder unit according to claim 1, wherein

said structure device of said conductor is formed from a litz wire or a rope.

8. The transponder unit according to claim 1, wherein

said conductor is formed as wire.

9. The transponder unit according to claim 1, wherein

said conductor is formed by etching as a coating of an antenna substrate.

2. The transponder unit comprising:

a transponder unit for transponder cards, identification documents or suchlike, having at least one chip and at least one antenna, wherein said antenna is formed from a metal conductor which is arranged on an antenna substrate and is integrally connected to the latter,

wherein said conductor is provided with a structure device which is integrally connected to said conductor and is operable to form a composite conductor such that said composite conductor has a higher elongation at break than the conductor.

10. The transponder unit according to claim 2, wherein said structure device of said conductor substantially consists of at least one metal material.

11. The transponder unit according to claim 2, wherein said structure device of said conductor is at least an alloy component of said conductor.

12. The transponder unit according to claim 2, wherein said structure device of said conductor is at least a cover layer of said conductor.

13. The transponder unit according to claim 12, wherein said cover layer of said conductor is formed by diffusion.

14. The transponder unit according to claim 2, wherein said structure device of said conductor is formed from a litz wire or a rope.

15. The transponder unit according to claim 2, wherein said conductor is formed as wire.

16. The transponder unit according to claim 2, wherein said conductor is formed by etching as a coating of an antenna substrate.
