Item-level tagging (ILT) has put a strict demand on the size and cost of tags. Near-field UHF RFID is believed to be one solution to implement ILT. To reduce the size and cost of tags to the minimum, on-chip antennas (OCA) utilizing near-field coupling are studied in this paper. Full-wave electromagnetic solvers are used to aid OCA design, and measurement results are presented to demonstrate the feasibility of UHF tags with OCA embedded.
After a trademark dispute, the EPC Prototyping Platform is now called "Fosstrak" (previously Accada). Fosstrak stands for "free and open source software for track and trace".
