Abstract

The invention relates to a chip module for an RFID system, in particular for an RFID-label, a coupling label for use in an RFID-label, an RFID-Inlay for an RFID-label, and an RFID label produced using an RFID inlay on a strip-shaped backing material (5, 8), in particular a backing film; an RFID chip (3) and a coupling antenna (4) that is electrically, in particular galvanically, connected to the RFID-chip (3), are arranged on the strip-shaped backing material.

Claims

1. A chip module for an RFID system wherein an RFID chip and a coupling antenna (4) connected galvanically with the RFID chip are provided on a backing strip.

2. The chip module according to claim 1 wherein the RFID chip is directly attached on the flat coupling antenna.

3. A self-adhesive coupling label for use in an RFID label wherein a lower face of the backing film of a chip module according to claim 1 has an adhesive layer covered by a removable separating strip or sheet.

4. An RFID inlay for an RFID label wherein a chip module according to claim 1 is glued with its backing strip onto a flat RFID antenna in such a position that the coupling antenna and the RFID antenna are inductively coupled.

5. The RFID inlay according to claim 4 wherein the flat RFID antenna is provided on an antenna film that has on its back face a pressure-sensitive adhesive layer covered by a separating layer.

6. The RFID inlay according to claim 4 wherein a coupling region of the RFID antenna is wider than a coupling region of the coupling antenna.

7. An RFID label wherein an RFID inlay according to claim 4 is provided between a cover strip or sheet provided with a pressure-sensitive adhesive layer on its lower face, and a backing strip or sheet that can be removed from the pressure-sensitive adhesive layer.

8. An RFID system that wherein a coupling label according to claim 3 is glued onto the RFID antenna of a package and its coupling antenna is inductively coupled with the RFID antenna of the package.
