urn:hdl:2072/411460 A high-gain passive UHF-RFID tag with increased read range Zuffanelli, Simone Aguilà Moliner, Pau Zamora González, Gerard Paredes Marco, Ferran Martín, Ferran Bonache Albacete, Jordi Dipole antennas Impedance matching Radio-frequency identification (RFID) In this work, a passive ultra-high frequency radio-frequency identification UHF-RFID tag based on a 1.25 wavelengths thin dipole antenna is presented for the first time. The length of the antenna is properly chosen in order to maximize the tag read range, while maintaining a reasonable tag size and radiation pattern. The antenna is matched to the RFID chip by means of a very simple matching network based on a shunt inductance. A tag prototype, based on the Alien Higgs-3 chip, is designed and fabricated. The overall dimensions are 400 mm × 14.6 mm, but the tag width for most of its length is delimited by the wire diameter (0.8 mm). The measured read range exhibits a maximum value of 17.5 m at the 902-928 MHz frequency band. This represents an important improvement over state-of-the-art passive UHF-RFID tags. 2016 Article Ministerio de Economía y Competitividad TEC2013-40600-R Agència de Gestió d'Ajuts Universitaris i de Recerca 2014/SGR-157 Sensors (Basel, Switzerland) ; Vol. 16 No. 7 (July 2016) open access Aquest document està subjecte a una llicència d'ús Creative Commons.
