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. An RFID label comprising:

a cover sheet having an upper face and a lower face;

an RFID chip;

a coupling antenna bonded between the RFID chip and the upper face of the cover sheet and having a coupling region;

an antenna film having an upper face and a lower face;

a pressure-sensitive adhesive layer on the lower face of the cover sheet;

a flat RFID antenna bonded by the pressure-sensitive adhesive layer to the lower face of the cover sheet and having a coupling region fixed to the upper face of the antenna film at the coupling region thereof, the coupling region of the RFID antenna being wider than the coupling region of the coupling antenna;

a pressure-sensitive adhesive layer on the lower face of the antenna film; and

a separating sheet secured to the pressure-sensitive adhesive layer of the antenna film.
