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. ## Claims ### Claim 1 A method for forming at least one antenna for a radio frequency identified (RFID) enabled mirror, comprising: depositing a reflective layer on a substrate; selectively removing at least a portion of the reflective layer to form the at least one antenna; and applying a dielectric coating to the substrate to replace the removed at least a portion of the reflective layer. ### Claim 2 (depends on 1) The method of claim 1, further comprising depositing a protective layer on the reflective layer. ### Claim 3 (depends on 2) The method of claim 2, where the protective layer includes a backing adapted to prevent exposure of the reflective layer to corrosive substances. ### Claim 4 (depends on 1) The method of claim 1, further comprising coupling an RFID chip to the at least one antenna via one of inductive coupling and capacitive coupling. ### Claim 5 (depends on 1) The method of claim 1, wherein the at least one antenna comprises at least one of a loop antenna and slot corresponding to the removed portion of the reflective layer. ### Claim 6 (depends on 1) The method of claim 1, wherein removing the at least a portion of the reflective layer comprises selectively removing a first portion and a second portion of the reflective layer to form a first antenna and a second antenna. ### Claim 7 (depends on 6) The method of claim 6, wherein the first antenna is configured to resonate at a first frequency band and the second antenna is configured to resonate at a second frequency band. ### Claim 8 (depends on 1) The method of claim 1, wherein the substrate is one of glass, acrylic, and polycarbonate. ### Claim 9 (depends on 1) The method of claim 1, wherein the reflective layer comprises a layer of a first metal deposited on top of the substrate followed by a layer of a second metal different from the first metal. ### Claim 10 (depends on 1) The method of claim 1, wherein dielectric coating includes stacked layers of transparent dielectric material adapted to modify the reflective properties of the substrate. ### Claim 11 (depends on 1) The method of claim 1, wherein the dielectric coating comprises substantially the same reflective properties as the reflective layer. ### Claim 12 (depends on 1) The method of claim 1, wherein selectively removing the at least a portion of the reflective layer comprises applying a demetallizing solution to the reflective layer to remove the at least a portion of the reflective layer while preserving the remaining portion of the reflective layer that corresponds to the at least one antenna. ### Claim 13 A method for forming at least one antenna for a radio frequency identified (RFID) enabled mirror, comprising: depositing a reflective layer on a substrate, the reflective layer comprises a dielectric coating; selectively removing at least a portion of the reflective layer corresponding to the at least one antenna; and depositing a metallic material where the at least a first portion was removed to form the at least one antenna. ### Claim 14 (depends on 13) The method of claim 13, further comprising depositing a protective layer on the reflective layer. ### Claim 15 (depends on 14) The method of claim 14, where the protective layer includes a backing adapted to prevent exposure of the reflective layer to corrosive substances. ### Claim 16 (depends on 13) The method of claim 13, further comprising coupling an RFID chip to the at least one antenna via one of inductive coupling and capacitive coupling. ### Claim 17 (depends on 13) The method of claim 13, wherein the at least one antenna comprises at least one of a loop antenna and a slot corresponding to the removed portion of the reflective layer. ### Claim 18 (depends on 13) The method of claim 13, wherein removing the at least a portion of the reflective layer comprises selectively removing a first portion and a second portion of the reflective layer corresponding to a first antenna and a second antenna, respectively. ### Claim 19 (depends on 18) The method of claim 18, wherein the first antenna is configured to resonate at a first frequency band and the second antenna is configured to resonate at a second frequency band. ### Claim 20 (depends on 13) The method of claim 13, wherein the substrate is one of glass, acrylic, and polycarbonate. ### Claim 21 (depends on 13) The method of claim 13, wherein dielectric coating includes stacked layers of transparent dielectric material adapted to modify the reflective properties of the substrate. ### Claim 22 (depends on 13) The method of claim 13, wherein the dielectric coating comprises substantially the same reflective properties as the metallic material.
