UNITAG - Universal UHF RFID Tag based on System-Level Modeling and Optimization

Project: Research project

Project Details


RFID (Radio Frequency Identification) technologies, and especially the UHF (Ultra High Frequency) sector within represent a rapidly growing market. The Class-1, Generation-2 standard developed by the organisation EPCglobal comprised of industry leaders and organisations focused on creating global standards for the Electronic Product Code (EPC) targets this market by establishing the basis for passive, long-range, extremely low-cost Tags. The functionality of those Tags is basically reduced to providing a unique identifier (UID) to any reader which transmits a query request defined in the standard. State-of-the-art Tags are capable of operating in a range of several meters depending on the application the Tag is serving. Enhancing the read range and reducing the number of hard-to-read or non-readable Tags is one of the most challenging design criteria for these Tags. The proposed project UNITAG suggests a novel design methodology which bundles the requirements on the UHF RFID Tag at the system-level and develops the Tag in a top-down design process. We are convinced that this design methodology will bring an enhancement in Tag performance by eliminating the need to adapt to existing, possibly suboptimal solutions. Our design methodology will enable a system-level simulation and optimization by employing a behavioral modeling of the Tags building blocks taking account of the strong interoperation between those blocks. We plan to implement the Tag concepts obtained by the system-level description in prototype Tags, hence verifying the idea of the developed design methodology.
