Passive Ultrawide Bandwidth RFID

Abstract

Ultrawide bandwidth (UWB) technology is a promising solution for next generation radiofrequency identification (RFID) systems to overcome most of the main limitations of current RFID systems such as very short operating range, insufficient ranging resolution for accurate localization, sensitivity to interference and scarce multiple access capability. In this paper, the UWB technology is applied to (semi-)passive RFID based on backscatter modulation and the potential performance is investigated in terms of range/data rate trade-off and clutter effect mitigation using experimental data.This full text paper was peer reviewed at the direction of IEEE Communications Society subject matter experts for publication in the IEEE "GLOBECOM" 2008 proceedings.978-1-4244-2324-8/08/$25.00

Architectures and protocols for fast identification in large-scale RFID systems

“…The adoption of UWB technology in RFID systems has been advocated in recent literature to support accurate real-time localization, security, and large-scale system management [2], [16]. However, the possible integration with the existing standard UHF RFID technology has not been investigated yet and is one of the targets of GRETA project.…”

Time-Domain Measurement of Time-Coded Uwb Chipless Rfid Tags

“…Here, the simplest way to code information is by varying the physical length of an open-ended transmission line connected to a scattering UWB antenna. Although this idea has been proposed by some authors [14][15][16][17], there are few experimental results [14][15][16][17], which have been obtained by means of high-cost instruments such as vector network analyzers (VNA). Future implementations of commercial readers should be based on low-cost equipments, such as IR-UWB radars.…”

“…In [10,11], printable chipless RFID tags based on multiresonators have been reported; here information is coded in frequency. An alternative method where the information is coded in time has been proposed in [14][15][16][17]. Here, the simplest way to code information is by varying the physical length of an open-ended transmission line connected to a scattering UWB antenna.…”

“…UWB chipless RFID systems might be a promising solution for low-cost item tagging [10][11][12][13][14][15][16][17]. Chipless tags based on surface acoustic waves (SAW) are already commercially available [18][19][20].…”

UWB Antennas: Design and Modeling

“…Indeed, promises have been highlighted in order to achieve larger operating range, accurate localization, robustness to interference and more security in multiple access systems (Zou et al, 2007;Hu et al, 2007;Dardari & D'Errico, 2008). Further, when the wireless systems that are potential candidates for cognitive radio are considered, UWB seems to be one of the tempting choices because it has an inherent potential to fulfill some of the key requirements of cognitive radio (Manteuffel et al;.…”
