Device and method for reading and/or writing data from and/or to a multiplicity of RFID chips

1. A device for reading and/or writing data from and/or to a multiplicity of RFID chips arranged in smart labels within a smart label production device, wherein the smart labels each comprising a first antenna are applied next to and behind one another on a common continuous film-like strip, characterised in that each smart label from a selected set of smart labels arranged next to and/or behind one another is respectively assigned a second antenna for the simultaneous transmissions of read and/or write data between the first and second antennas by means of ultrahigh frequency waves, wherein the second antennas are arranged in a planar manner within at least one common antenna carrier, wherein each second antenna is arranged with its entire antenna body and in each case an associated read and/or write element within a depression of the antenna carrier, which is of flat design on its surface facing towards the strip.

2. The device according to claim 1 , characterised in that a distance between the surface and the second antenna inserted in the depression is adjustable and/or a rotation angle of a rotation of the second antenna, which can be carried out about an axis of rotation perpendicular to the surface, is adjustable.

3. The device according to claim 1 , characterised in that air holes for sucking the strip against the surface during the transmission of the read and/or write data are arranged in depression-free regions of the surface of the antenna carrier.

4. The device according to claim 1 , characterised in that the surface is at least partially made of metal.

5. The device according to claim 1 , characterised in that the second antennas arranged on the at least one common antenna carrier have different UH transmission frequencies.

6. The device according to claim 1 , characterised in that two second antennas arranged adjacent to one another on the at least one common antenna carrier emit differently polarised electromagnetic waves.

7. The device according to claim 1 , characterised in that one or more second antennas is/are designed as two intersecting double dipoles.

8. The device according to claim 1 , characterised by a second antenna carrier which can be displaced in the longitudinal and transverse direction of the base with respect to a first antenna carrier.

9. A method for reading and/or writing data from and/or to a multiplicity of RFID chips arranged in smart labels within a smart label production device, wherein the smart labels each comprising a first antenna are applied next to and behind one another on a common continuous film-like strip, characterised in that each smart label from a selected set of smart labels arranged next to and/or behind one another is respectively assigned a second antenna for simultaneously transmitting read and/or write data between the first and second antennas by means of ultrahigh frequency waves, wherein the second antennas are arranged in a planar manner within at least one common antenna carrier and each second antenna is arranged with its entire antenna body and in each case an associated read and/or write element within a depression of the antenna carrier, which is of flat design on its surface facing towards the strip.

10. The method according to claim 9 , characterised in that the second antennas transmit the data at different UH transmission frequencies.

11. The method according to claim 9 , characterised in the two adjacent second antennas emit electromagnetic waves with different polarisation.

12. The method according to claim 9 , characterised in that a distance between a surface of the flat antenna carrier and the second antennas inserted within depressions of the antenna carrier is adjusted.

13. The method according to claim 9 , characterised in that the reading and/or writing of the data represents an initialisation of the RFID chip.

14. The method according to claim 9 , characterised in that the reading of the data represents a method for testing the RFID chips.
