Advanced Passive UHF RFID Tags for Efficient Tracking of Metallic Objects

The paper discusses innovative passive UHF RFID tags designed for tracking metallic objects, addressing the challenges posed by the presence of metal, water, and plastic. The featured tags, including the Adamas and Portunus tags, offer exceptional performance, remaining reliable regardless of the attached object's composition. Key features include low-cost manufacturing, high-speed assembly, and a rugged structure suitable for demanding environments. These tags are expected to see commercial availability in mid-2007, providing a viable solution for enhancing supply chain management, especially in cardboard applications.
