Abstract

The RF antenna portion and the RFID electronics portion of an RFID tag are produced separately and assembled on the item to be tagged. This reduces the overall cost of the RFID tagging process, in addition to providing other benefits. Specifically, the RF antenna is pre-applied to an item that is to be tagged and the RFID electronics are applied separately to the item in the form of a discrete RFID electronics module that couples to the pre-applied RF antenna to provide an RFID capability for the item.

Claims

1. A method, comprising:

providing an RF antenna on an item; and

electrically coupling a separate RFID electronics module to the RF antenna on the item after the RF antenna is provided on the item;

thereby providing an RFID capability for the item.

2. The method of claim 1, wherein electrically coupling comprises attaching the RFID module to the Item to provide an RFID function for the item.

3. The method of claim 1 wherein the electrical coupling between the RF antenna and the RFID electronic module is a non-contact electrical coupling method.

4. The method of claim 1, wherein the item includes an inside surface and an outside surface and further comprising providing the RF antenna on the inside surface of the Item and attaching the RFID electronics module in an adjacent position to the outside surface of the item.

5. The method of claim 1, further comprising:

providing the RF antenna with a first set of contact pads;

providing the RFID module with a second set of contact pads; and

aligning the first and second set of contact pads in a predetermined manner relative to each other when attaching the RFID module to the item whereby the RFID module is non-contact electrically coupled to the RF antenna.

6. The method of claim 1, further comprising providing a dielectric between the RF antenna and the RFID electronic module.

7. A method comprising,

applying an RF antenna directly to an item;

providing an RFID electronics module separate from the item and the RF antenna on the item, the RFID electronics module including electronics that provide an RFID capability when coupled to the RF antenna;

applying the RFID electronics module to the item after applying the RF antenna to the item, whereby the RFID electronics module is electrically coupled to the RF antenna.

8. The method of claim 7, further comprising:

providing alignment features on the item and positioning the RFID electronics module on the item based on a location of the alignment features.

9. The method of claim 7, further comprising providing an adhesive on the RFID electronics module;

and applying the RFID electronics module to the item by means of the adhesive.

10. The method of claim 7, further comprising applying the RFID electronics module to the item such that the RFID electronics module is non-contact electrically coupled to the RF antenna.

11. The method of claim 7, further comprising applying the RFID electronics module to the item such that the RFID electronics module is in direct electrical contact with the RF antenna.

12. The method of claim 7, wherein applying the RF antenna to the Item comprises printing the RF antenna on the item.

13. The method of claim 12 wherein the RF antenna is printed on the item using electrically conductive ink.

14. In combination, an item having at least one surface and an RF antenna applied to the surface;

and an RFID electronics module separate from the item and from the RF antenna on the item, the RFID electronics module including electronics which provide an RFID capability when coupled to the RF antenna, the RFID electronics module being applied to the item so as to be electrically coupled to the RF antenna and provide an RFID capability for the item.

15. The combination of claim 14, further comprising an adhesive attaching the RFID electronics module to the Item.

16. The combination of claim 14, further comprising a dielectric between the RFID electronics module and the RF antenna.

17. The combination of claim 14, wherein the RFID module is adapted to have its RFID capability modified if the RFID electronics module is tampered or removed from the item.
