On the Design and Miniaturization of Passive UHF RFID Transponder Antenna
Résumé
UHF RFID is an emerging technology taking profits of the development of low cost passive RFID transponder taking advantages of the backscatter modulation principle. Therefore the EPC Global, an international organisation driving the development of standards for the electronic identification of products, leads toward item level identification using RFID. But, excluding ethical issues that could be an opposition to this decision, it is believed that such a resolution will be economically viable only if RFID tag cost falls under 0.10 € each and that the RFID tag world production capacity reaches several hundreds of million of tags a year. To attain this objective, RFID tag miniaturization could be a solution as it could allow increasing the tag production capacity (then allow decreasing tag cost) as well as it permits RFID tags to be less noticeable.
