Dual-band UHF-RFID tags based on meander line antennas loaded with spiral resonators Paredes, Ferran Zamora González, Gerard Herraiz-Martínez, Francisco Javier Martín, Ferran Bonache Albacete, Jordi Radio frequency identification (RFID) Spiral resonator (SR) Dual-band Impedance matching Meander line antenna (MLA) The purpose of this letter is to implement dual-band tags for ultrahigh-frequency (UHF) radio frequency identification (RFID) applications operative in Europe and the US. Since the regulated bands of UHF-RFID in Europe (867 MHz) and the US (915 MHz) are close, broadband tags might be also considered. However, it is demonstrated in this letter that the performance of dual-band tags designed to operate at the frequency bands of interest is superior to that of broadband (monoband) tags. A meander-line antenna (MLA) has been considered for tag implementation. The dual-band functionality is achieved through a perturbation method consisting of coupling an electrically small resonator [a two-turn spiral resonator (2-SR)] to the antenna. The analysis, design, and fabrication of a dual-band UHF-RFID tag has been carried out. The measured performance of the fabricated prototype is in good agreement with theory. Measured read ranges of 6 and 8 m at the European and US frequency bands, respectively, have been obtained 2011 Article Ministerio de Ciencia e Innovación TEC2010-17512 Ministerio de Ciencia e Innovación CSD2008-00066 Ministerio de Industria, Turismo y Comercio TSI-020100-2009-778 Ministerio de Industria, Turismo y Comercio TSI-020100-2010-493 Agència de Gestió d'Ajuts Universitaris i de Recerca 2009/SGR-421 IEEE antennas and wireless propagation letters ; Vol. 10 (July 2011), p. 768-771 open access Aquest material està protegit per drets d'autor i/o drets afins.
