Patent ID: 8851389

Claim:
A multilayer RFID tag for securing to a metallic object comprising: an adhesive first layer; a second layer having a first side, a second side, a top surface and a bottom surface wherein the second layer is rigid so as to provide support for the tag and wherein the rigid second layer allows the tag to extend tangentially outward from the object in a non-flush manner with respect to the object wherein the adhesive first layer is only located at the first side of the bottom surface of the second layer and wherein the second side of the bottom surface of the second layer does not have an adhesive and does not come into contact with the object; wherein the second layer has a greater surface area than the first layer and wherein the second layer is rigid and does not fold, but adopts an identical curvature as any curvature of the object the RFID tag is secured to; an electronic third layer wherein the electronic third layer has RFID circuitry having an RFID element and an antenna element and wherein the electronic third layer is located closer to the second side of the second layer than to the first side of the second layer to reduce electrical interference; a fourth layer having a top surface and a bottom surface and wherein the second layer is located between the first layer and the electronic third layer and wherein the electronic third layer is located between the second layer and the fourth layer and wherein the electronic third layer is completely surrounded by the second layer and fourth layer and wherein all the layers are secured together to form a single inseparable unit having a first end and a second end; and wherein the rigid second layer allows the RFID circuitry of the third layer to be located away from and not in direct contact with the metallic object therein reducing electrical interference between the RFID circuitry of the third layer and the metallic object.
