Abstract
An RFID tag device is disclosed that is designed to operate on difficult substrates, such as dielectric surfaces with high loss, organic material surfaces, or metallic surfaces. The RFID tag device comprises an RFID antenna structure formed on one side of a thermoplastic substrate component with an RFID chip coupled to it in a roll to roll process. The substrate component is then deformed into a series of cavities with the RFID antenna structure within the cavities. Specifically, the RFID antenna structure is positioned fully on a top surface of the cavity, or positioned partially in a top and partially on an edge/bottom of the cavity.
