Bandwidth limitations of ultra high frequency-radio frequency identification tags
Zamora González, Gerard; Paredes Marco, Ferran; Herraiz Martínez, Francisco Javier; Martín Antolín, Ferran; Bonache Albacete, Jordi (16/07/2013)Fundamental bandwidth limitations on the design of ultra high frequency (UHF) radio frequency identification (RFID) tags are investigated. This study was conducted by considering the optimum equivalent-circuit network ... -
Chipless RFID system based on magnetoinductive-wave (MIW) delay lines
Herraiz Martínez, Francisco Javier; Ugarte Muñoz, Eduardo; Segovia Vargas, Daniel; Paredes Marco, Ferran; Zamora González, Gerard; Martín Antolín, Ferran; Bonache Albacete, Jordi (Sin editorial (Nagoya, Japón), 29/10/2012)A novel fully passive and electromagnetic chipless radiofrequency identification (RFID) system is proposed. The system is based on printed tags implemented with magnetoinductive-wave (MIW) delay lines. Such lines are ... -
Dual-band printed dipole antenna loaded with open complementary split-ring resonators for wireless applications
Herraiz Martínez, Francisco Javier; Paredes Marco, Ferran; Zamora González, Gerard; Martín Antolín, Ferran; Bonache Albacete, Jordi (01/04/2012)In this article, a printed dipole antenna loaded with open complementary split ring resonators is proposed. The integration of these particles inside the dipole structure provides dual-band behavior. Furthermore, a ... -
Dual-band RFID tags based on folded dipole antennas loaded with spiral resonators
Paredes Marco, Ferran; Zamora González, Gerard; Herraiz Martínez, Francisco Javier; Martín Antolín, Ferran; Bonache Albacete, Jordi (Sin editorial (Tucson, Estados Unidos de América), 05/03/2012)The purpose of this paper is to demonstrate the possibility of implementing folded dipole antennas operative at two closely spaced frequencies of interest, for instance, in ultra-high-frequency radio frequency identification ... -
Dual-band UHF-RFID tags based on meander-line antennas loaded with spiral resonators
Paredes Marco, Ferran; Zamora González, Gerard; Herraiz Martínez, Francisco Javier; Martín Antolín, Ferran; Bonache Albacete, Jordi (25/07/2011)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 ... -
Free-space and on-metal dual-band tag for UHF-RFID applications in Europe and USA
Paredes Marco, Ferran; Zamora González, Gerard; Zuffanelli, Simone; Herraiz Martínez, Francisco Javier; Martín Antolín, Ferran; Bonache Albacete, Jordi (01/09/2013)In this paper, we present an UHF-RFID tag mountable on metallic surfaces and capable to operate in the assigned frequency bands in Europe (866-869 MHz) and USA (902-928 MHz). Due to the proximity of these frequency bands, ... -
Fundamental mode leaky-wave-antenna (LWA) using slot line and split-ring-resonator(SRR)-based metamaterials
Zamora González, Gerard; Zuffanelli, Simone; Paredes Marco, Ferran; Herraiz Martínez, Francisco Javier; Martín Antolín, Ferran; Bonache Albacete, Jordi (28/10/2013)A new composite right/left-handed (CRLH) slotline leaky-wave antenna (LWA) is proposed. The antenna, implemented by loading a slotline with split-ring resonators (SRRs), is designed to exhibit a balanced dispersion relation, ... -
Multiband printed monopole antennas loaded with OCSRRs for PANs and WLANs
Herraiz Martínez, Francisco Javier; Zamora González, Gerard; Paredes Marco, Ferran; Martín Antolín, Ferran; Bonache Albacete, Jordi (22/12/2011)Multiband printed monopole antennas loaded with open complementary split-ring resonators (OCSRRs) are presented. The OCSRRs, modeled as parallel LC resonant tanks, act as high-impedance elements at their resonance frequencies, ... -
