Abstract

A radio frequency identification (RFID) enabled mirror includes a mirror comprising a reflective layer. The reflective layer comprises at least one layer of a metallic material. At least one portion of the reflective layer is removed to form a booster antenna from a remaining portion of the reflective layer. A dielectric coating is applied to the mirror where the reflective layer was removed. The RFID-enabled mirror further includes an RFID chip coupled to the booster antenna.

First claim

What is claimed is:

1. A radio frequency identification (RFID) enabled mirror, comprising:
a mirror comprising a reflective layer, wherein:
the reflective layer comprises at least one layer of a metallic material;
at least one portion of the reflective layer is removed to form a booster antenna from a remaining portion of the reflective layer; and
a dielectric coating is applied to the mirror where the reflective layer was removed; and

an RFID chip coupled to the booster antenna.

2. The RFID-enabled mirror of claim 1 , wherein the RFID chip is coupled to the booster antenna via one of inductive coupling and capacitive coupling.

3. The RFID-enabled mirror of claim 1 , wherein the mirror further comprises a substrate, and wherein the reflective layer is deposited on the substrate.

4. The RFID-enabled mirror of claim 1 , wherein the booster antenna comprises a loop antenna.

5. The RFID-enabled mirror of claim 1 , wherein the booster antenna comprises a slot antenna having at least one slot corresponding to the removed portion of the reflective layer.

6. The RFID-enabled mirror of claim 1 , wherein the booster antenna is configured to resonate at a first frequency band.

7. The RFID-enabled mirror of claim 6 , wherein the booster antenna is further configured to resonate at a second frequency band.

8. The RFID-enabled mirror of claim 1 , wherein the RFID-enabled mirror comprises one of a rearview mirror and a side view mirror.

9. The RFID-enabled mirror of claim 1 , further comprising a switch adapted to control an operational state of the RFID-enabled mirror.

10. The RFID-enabled mirror of claim 9 , wherein the operational state of the RFID-enabled mirror corresponds to a number of occupants in a vehicle.

11. A radio frequency identification (RFID) enabled mirror, comprising:
a mirror comprising a reflective layer, wherein:
the reflective layer comprises a dielectric coating;
at least one portion of the reflective layer is removed; and
a metallic material is applied to the mirror where the reflective layer was removed to form a booster antenna; and

an RFID chip coupled to the booster antenna.

12. The RFID-enabled mirror of claim 11 , wherein the RFID chip is coupled to the booster antenna via one of inductive coupling and capacitive coupling.

13. The RFID-enabled mirror of claim 11 , wherein the mirror further comprises a substrate, and wherein the reflective layer is deposited on the substrate.

14. The RFID-enabled mirror of claim 11 , wherein the booster antenna comprises a loop antenna.

15. The RFID-enabled mirror of claim 11 , wherein the booster antenna comprises a slot antenna having at least one slot corresponding to the removed portion of the reflective layer.

16. The RFID-enabled mirror of claim 11 , wherein the booster antenna is configured to resonate at a first frequency band.

17. The RFID-enabled mirror of claim 16 , wherein the booster antenna is further configured to resonate at a second frequency band.

18. The RFID-enabled mirror of claim 11 , wherein the RFID-enabled mirror comprises one of a rearview mirror and a side view mirror.

19. The RFID-enabled mirror of claim 11 , further comprising a switch adapted to control an operational state of the RFID-enabled mirror.

20. The RFID-enabled mirror of claim 19 , wherein the operational state of the RFID-enabled mirror corresponds to a number of occupants in a vehicle.
