Passive UHF RFID Tags for Tracking Metallic ObjectsMutharasu Sivakumar, Naaser Mohammed, Supreetha Aroor, Daniel D. Deavours Tagging Metallic Objects – The Challenge The Adamas Tag • Objects near RFID tag affects performance Air-Plastic-Water-Metal Performance max min • Highest performing tag • Performance independent of attached object • Low cost and high speed assembly • Expected commercial availability July 2007 • Planar microstrip antenna technology offers commercially viable solution The Portunus Tag Tracking Metal in Supply Chain • Good performance on metal • Rugged structure for toughest environments • Convenient profile fits numerous applications • Expected commercial availability September 2007 • Cardboard boxes ubiquitous in supply chain • RFID use limited by metals, foils and liquids • Applying new metal tag technology to cardboard • Tag performance independent of contents and humidity
