Abstract

A RFID label for use on a lid of a container, and a method of using the RFID label. The RFID label comprises a substrate component, a RFID antenna formed on the substrate component, and a RFID chip for storing data coupled to the RFID antenna. The RFID label is positioned or configured on the lid so as to limit or avoid any interference between the RFID antenna and the RFID chip by any metal component of the container. The RFID label is particularly useful for containers that have small lids or metal components, such as vials, where conventional RFID usage is limited.

First claim

What is claimed is:

1. A RFID label for use with a container having a lid with a metallic component, the RFID label comprising:
a substrate component that is substantially circular;
a RFID antenna comprising a slotted-loop antenna arranged entirely on a first side of the substrate component and attached or adhered to the first side of the substrate component;
a RFID chip on the first side of the substrate component and coupled to the RFID antenna;
and a spacer element arranged facing the first side of the substrate component;
wherein when the RFID label is attached to an external surface of the lid, the spacer element arranged between the lid and the substrate provides a separation between the RFID antenna and the lid.

2. The RFID label of claim 1 , wherein the RFID antenna comprises a conductor sheet and a slot formed into the conductor sheet.

3. The RFID label of claim 2 , wherein the slot comprises a closed end and an open end.

4. The RFID label of claim 1 , wherein the RFID antenna generates a top-side field.

5. The RFID label of claim 1 , wherein the container is a vial.

6. The RFID label of claim 1 , wherein the container is used to store medication, biological samples, liquids, or powders.

7. The RFID label of claim 1 , wherein the RFID chip is in electrical communication with the conductor sheet.

8. The RFID label of claim 1 , wherein the RFID chip functions as a digital memory.

9. The RFID label of claim 1 , wherein the RFID chip is encoded with information relating to a content of the container.

10. The RFID label of claim 1 , wherein the RFID antenna is located spaced apart from any metal component of the container.

11. The RFID label of claim 1 , wherein the RFID antenna generates a read range of greater than one inch.

12. The RFID label of claim 1 , wherein the spacer element increases distance between the RFID antenna and the metallic component of the lid and decreases interference of the RFID antenna with the metallic component.

13. A RFID label for use with a container having a metal component, the RFID label comprising:
a substrate component that is substantially circular;
a RFID slotted loop antenna formed entirely on a first side of the substrate component;
a RFID chip on the first side of the substrate component and coupled to the RFID antenna;
and a spacer element arranged facing the first side of the substrate component;
wherein when the RFID label is attached to an external surface of the container, the spacer element arranged between the metal component and the substrate provides a separation between the RFID antenna and the metal component of the container.

14. The RFID label of claim 13 , wherein the RFID label is adhered to an external surface of a lid of the container.

15. The RFID label of claim 13 , wherein the container is a vial.

16. The RFID label of claim 13 , wherein the RFID antenna generates a top-side field.

17. The RFID label of claim 13 , wherein the RFID antenna generates a read range of greater than one inch.

18. A method of using a RFID in conjunction with a container having a lid, the method comprising:
providing a RFID label comprising a substrate component, a RFID antenna comprising a slotted-loop antenna arranged entirely on a first side of the substrate component and attached or adhered to the substrate component, and a RFID chip on the first side of the substrate component and coupled to the RFID antenna;
arranging a spacer element on the lid;
securing the RFID label on an external surface of the lid such that the spacer element is arranged between the lid and the substrate ; and
positioning the RFID label on the lid in a manner so as to generate a top side field for achieving a read range of greater than one inch with a RFID reader.
