Abstract

A contactless RF-ID label including an antenna and a computer chip, wherein the antenna extends in three spatial directions.

Claims

1. A contactless RF-ID label comprising an antenna and a computer chip, wherein the antenna extends in three spatial directions.

2. The label according to claim 1, wherein the antenna is a strip of an electrically conductive material.

3. The label according to claim 1, wherein the antenna is coiled up on itself to form a coil of cylinders of concentric diameters.

4. The label according to claim 2, wherein the antenna has a radial loop implemented on the strip.

5. The label according to claim 1, wherein the antenna is affixed or deposited on an electrically nonconductive substrate.

6. The label according to claim 1, wherein the antenna has a U shape.

7. The label according to claim 1, wherein the computer chip is attached to both ends of the antenna.

8. The label according to claim 1, arranged in a case or casing.

9. The label according to claim 8, wherein the casing is filled with a plastic material.

10. The label according to claim 3, wherein the largest diameter of the cylinders formed by coiling up the antenna is in a range of about 4 and about 9 millimeters.

11. The label according to claim 1, wherein the antenna operates at a frequency of 13.56 MHz.

12. The label according to claim 1, wherein the antenna operates at a frequency of 2.45 GHz.

13. The label according to claim 1, wherein the antenna operates at an ultrahigh frequency (UHF).

14. A method of manufacturing a contactless label according to claim 1, comprising etching a conductive metal piece;

cutting a support out from the conductive metal; and

coiling up a plastic film on which was previously affixed the conductive metal.

15. A bottle or container comprising an essentially cylindrical part having at least one label according to claim 1.
