Abstract

Claims (34)

1. A wearable device comprising:

a printed circuit board;

a conductive housing;

an antenna;

a cover having an outer surface; and

a label comprising a film and a parasitic element, wherein the parasitic element is located between the film and the outer surface of the cover.

2. The wearable device of claim 1 , wherein the parasitic element comprises a conductive ink layer.

3. The wearable device of claim 1 , wherein the label is insert molded onto the outer surface of the cover.

4. The wearable device of claim 1 , wherein the label comprises a decorative ink layer between the film and the parasitic element.

5. The wearable device of claim 4 , wherein the label comprises a non-conductive masking ink layer between the decorative ink layer and the parasitic element.

6. The wearable device of claim 5 , wherein the label comprises a first insulating ink layer.

7. The wearable device of claim 6 , wherein the label comprises a first gloss layer between the non-conductive masking ink layer and the first insulating ink layer.

8. The wearable device of claim 6 , wherein the label comprises a second insulating ink layer, wherein the parasitic element is between the first insulating ink layer and the second insulating ink layer.

9. The wearable device of claim 8 , wherein the label comprises a bonding layer, wherein the bonding layer connects the label to the outer surface of the cover.

10. The wearable device of claim 9 , wherein the label comprises a second gloss layer between the second insulating ink layer and the bonding layer.

11. The wearable device of claim 1 , wherein the antenna is a slot antenna defined by a gap between the printed circuit board and the conductive housing.

12. A label for a wearable device containing an antenna, the label comprising multiple layers including a film, a decorative ink layer, a non-conductive masking ink layer, a first insulating ink layer, a parasitic element, and a second insulating ink layer, wherein the multiple layers of the label are applied onto the film, further wherein the parasitic element comprises a conductive ink layer.

13. The label of claim 12 , further comprising a bonding layer.

14. The label of claim 12 , further comprising a first gloss layer.

15. The label of claim 12 , wherein a portion of the conductive ink layer is exposed and free of additional layers printed thereon.

16. The label of claim 12 , wherein the label is configured for being joined to a plastic cover during an insert molding process.

17. The label of claim 12 , wherein the parasitic element is electrically grounded to the printed circuit board via radio-frequency grounding, direct current grounding, or a matching circuit.

18. A method of forming a label for a wearable device containing an antenna, the method comprising:

printing one or more layers of non-conductive masking ink onto a film;

printing one or more layers of conductive ink onto the film to define a parasitic element;

printing a bonding layer onto the film to form the label; and

forming the label into a shape that matches a shape of a cover to which the label is to be applied.

19. The method of claim 18 , wherein the label is joined to an outer surface of the cover during an insert molding process, wherein the bonding layer joins the label to the cover.

20. The method of claim 18 , further comprising:

printing one or more layers of decorative ink onto the film.

21. The method of claim 18 , further comprising:

printing one or more layers of insulating ink onto the film.

22. The method of claim 18 , further comprising:

trimming the label to remove any excess.
