Screen Printed Antennas on Fiber-Based Substrates for Sustainable HF RFID Assisted E-Fulfilment Smart Packaging Hasselt University KU Leuven
Intelligent packaging is an emerging technology, aiming to improve the standard communication function of packaging. Radio frequency identification (RFID) assisted smart packaging is of high interest, but the uptake is limited as the market needs cost-efficient and sustainable applications. The integration of screen printed antennas and RFID chips as smart labels in reusable cardboard packaging could offer a solution. Although paper is an ...
SIW textile antennas as a novel technology for UWB RFID tags Ghent University
A wearable ultra-wideband (UWB) textile antenna based on substrate integrated waveguide technology is presented for application in the next generation radio-frequency identification (RFID) systems operating in the low-duty cycle restricted [3.4-4.8] GHz UWB band. The design of a UWB antenna for application in smart textiles is very challenging. For end users, the antenna should be unobtrusively integrated into smart textile and comfortable to ...
Efficient modeling of on-body passive UHF RFID systems in the radiative near-field Ghent University
A novel method is presented to accurately determine the operational range of an on-body, passive ultrahigh-frequency (UHF) radio frequency identification (RFID) system operating in the radiative near field, based on its far-field radiation patterns. To this end, an efficient algorithm based on 3-D multipole expansion of the electromagnetic fields is formulated. By combining the new operator with the simulated or measured stand-alone far-field ...
An efficient algorithm to determine the operational range of near-field on-body UHF RFID systems Ghent University
A new algorithm is proposed, leveraging a 3D multipole expansions of the electromagnetic fields, to accurately determine the operational range of a radiative near-field on-body radio-frequency identification (RFID) system based on its far field radiation patterns, simulated or measured, under realistic deployment conditions. We illustrate the advocated method by an interrogating 866 MHz standard gain horn (SGH) and a passive eighth-mode ...
Optimization of RFID Systems in Unfriendly Operating Environments KU Leuven
This work focused on HF RFID systems, where it was a goal to increase the reliability of the system. Especially in environments with metallic parts many problems occur. It became clear that many problems took place at the loop antenna of the RFID system. Therefore, we focussed on the design of loop antennas in order to increase the reliability of HF RFID systems. Although HF RFID systems are widely adopted by the industry, it was shown that the ...
Fully 3D-printed UHF RFID Antennas: Technological Comparison to Realize Conductive Elements KU Leuven
In this work, two promising Additive Manufacturing (AM)/3D-printing technologies, enable to realize conductive elements, are analysed, and compared with respect to the realisation of RFID applications. The selected techniques are the Fused Filament Fabrication (FFF) and Aerosol Jet® Printing (AJ® P), which have been compared, for the first time, by measuring the performance of an UHF RFID tag, specifically designed and realized for the scope. ...
Bidirectional Communication in an HF Hybrid Organic/Solution-Processed Metal-Oxide RFID Tag KU Leuven
The ambition of printing item-level RFID tags is one of the driving forces behind printed electronics research. Organic RFID tags have been shown, initially using p-type organic semiconductors [1-4]. The introduction of n-type organic semiconductors with reasonable performance made organic CMOS conceivable [5] and organic CMOS RFID tags were shown [6]. However, all currently reported organic RFID tags are based on a tag-talks-first principle: as ...
Hierarchical ECC-Based RFID Authentication Protocol KU Leuven
RFID (Radio Frequency Identification) technology enables readers to scan remote RFID tags, and label the objects and people to which they are attached. Current cryptographic authentication protocols deployed in heterogeneous environments are often not compatible, or reveal too much information to the RFID readers. To tackle this problem, we introduce the concept of RFID groups and propose a hierarchical RFID authentication protocol. By using ...
