Abstract:
In this paper, an innovative design strategy for UHFRFID tags mounted on optical discs (such as DVDs) is presented. By using the metal layer of the disc as themain radiating element, it is possible to overcome the severe limitations of the existing tags for disc identification in terms of read range and bandwidth. The design and synthesis process, based on the proposed circuit model of the tag, is described.A worldwideUHF-RFID tag prototype, for direct mounting on a DVD disc, is designed and fabricated. The measured read range demonstrates that the presented method drastically improves the performance within the whole UHF-RFID band (840–930 MHz), in comparison to the DVD tags found in the available literature.
