Abstract
Systems and methods for integrating radio-frequency identification (RFID) circuitry into flexible circuits are provided. An RFID integrated circuit can be embedded within a dielectric layer of a flexible circuit or between a dielectric layer and a conductive layer of the flexible circuit. Additionally or alternatively, an RFID antenna may be integrated into a conductive layer of the flexible circuit. Alternatively, both the integrated circuit and antenna of RFID circuitry may be provided off of the flexible circuit but an RFID connector coupling the integrated circuit and antenna may be integrated into the flexible circuit.
