This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The performance of commercial Radio Frequency Identification (RFID) tags is primarily limited by present techniques used for tag antenna design. Currently, industry techniques rely on identifying the RFID tag application (books, clothing, etc.) and then building antenna prototypes of different configurations in order to satisfy minimum read range requirements. However, these techniques inherently lack an electromagnetic basis and are unable to provide a low cost solution to the tag antenna design process. RFID tag performance characteristics (read-range, chip-antenna impedance matching, surrounding environment) can be very complex, and a thorough understanding of the RFID tag antenna design may be gained through an electromagnetic approach in order to reduce the tag antenna size and the overall cost of the RFID system. The research presented in this thesis addresses RFID tag antenna design process for passive RFID tags. With the growing number of applications (inventory, supply-chain, pharmaceuticals, etc), the proposed RFID antenna design process demonstrates procedures to design tag antennas for such applications. Electrical/geometrical properties of the antennas designed were investigated with the help of computer electromagnetic simulations in order to achieve optimal tag performance criteria such as read range, chip-impedance matching, antenna efficiency, etc. Experimental results were performed on the proposed antenna designs to compliment computer simulations and analytical modelling.

Download or read book UHF RFID Technologies for Identification and Traceability written by Jean-Marc Laheurte and published by John Wiley & Sons. This book was released on 2014-09-09 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: UHF Radio Frequency Identification (RFID) is an electronic tagging technology that allows an object, place or person to be automatically identified at a distance without a direct line-of-sight using a radio wave exchange. Applications include inventory tracking, prescription medication tracking and authentication, secure automobile keys, and access control for secure facilities. This book begins with an overview of UHF RFID challenges describing the applications, markets, trades and basic technologies. It follows this by highlighting the main features distinguishing UHF (860MHz-960MHz) and HF (125 kHz and 13.56 MHz) identifications, in terms of reading range, environmental sensitivity, throughput and safety. The architecture of the integrated circuits and the organization of the memory are then described. One chapter is devoted to the air interface protocol aspects, including coding, modulation, multi readers operation and anti-collision algorithms to manage the tag responses. Focus will be put upon the EPC Gen2 protocol adopted in the ISO 18000 Part 6. The core of the book will cover the design and manufacturing issues of RFID tags. The influence of the propagation medium (warehouse, libraries, etc.), the tag close environment (bottles, linens, containers, carton boxes,etc.) and the coupling between tags will also be carefully addressed. The final chapter is dedicated to an industrial use case in the supply chain management, either in the retail inventory or blood traceability.

This book was released on 2009-08-08 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a step-by-step discussion of the design and development of radio frequency identification (RFID) and RFID-enabled sensors on flexible low cost substrates for UHF frequency bands. Various examples of fully function building blocks (design and fabrication of antennas, integration with ICs and microcontrollers, power sources, as well as inkjet-printing techniques) demonstrate the revolutionary effect of this approach in low cost RFID and RFID-enabled sensors fields. This approach could be easily extended to other microwave and wireless applications as well. The first chapter describes the basic functionality and the physical and IT-related principles underlying RFID and sensors technology. Chapter two explains in detail inkjet-printing technology providing the characterization of the conductive ink, which consists of nano-silver-particles, while highlighting the importance of this technology as a fast and simple fabrication technique especially on flexible organic substrates such as Liquid Crystal Polymer (LCP) or paper-based substrates. Chapter three demonstrates several compact inkjet-printed UHF RFID antennas using antenna matching techniques to match IC's complex impedance as prototypes to provide the proof of concept of this technology. Chapter four discusses the benefits of using conformal magnetic material as a substrate for miniaturized high-frequency circuit applications. In addition, in Chapter five, the authors also touch up the state-of-the-art area of fully-integrated wireless sensor modules on organic substrates and show the first ever 2D sensor integration with an RFID tag module on paper, as well as the possibility of 3D multilayer paper-based RF/microwave structures.

Download or read book Passive UHF RFID Tag Antenna Design Using Graphite based Conductive Papers written by Michael Kurz and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emergence of passive ultra-high frequency (UHF) radio-frequency identification (RFID) systems has led to the annual production of RFID tags in the billions. Two graphite-based solutions developed at the Limerick Pulp and Paper Research Centre (LPPRC) were identified as possible candidates to achieve a more environmentally conscious tag with less complex manufacturing methods compared to what is currently available on the market. These materials are almost entirely composed of carbon and can be formed onto a biodegradable paper substrate using relatively simple methods. The materials’ intrinsic properties are characterized and a simulation profile is created to aid in the design of an optimized tag antenna. Conductivities of 600 S/m and 39,000 S/m are measured for the two graphite-ink and exfoliated-graphite based papers, respectively. Anechoic chamber read range measurements are performed using a commercial RFID reader. Maximum theoretical read ranges for prototype tags built using graphite-ink and exfoliated-graphite based papers are found to be 2.26 m and 6.83 m, respectively. Comparison of graphite-based tag prototypes and a commercial tag suggests that they are suitable for applications where the benefits of manufacturability and bio-degradability outweigh the disadvantage of a large antenna footprint. Six total designs with varying read ranges, complexities, sizes, and materials are found.

Download or read book Design and Optimization of Passive UHF RFID Tag Antenna for Mounting on Or Inside Material Layers written by Shuai Shao and published by . This book was released on 2015 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a first step, the effects of dielectric materials on an antenna's impedance match and radiation pattern are investigated. The detuning effect is quantified based on the theoretical frequency scaling and effective permittivity of a dielectric material of finite thickness. Using simple formulas, the operational range of a tag can be predicted without intensive full-wave simulations of different materials. Next, a spectral domain Green's function is applied to compute the antenna pattern when the tag is mounted on or inside a layered medium. The optimal placement of the tag is found based on the focusing effect that the material has on the gain pattern of the antenna. For tires, the steel ply in the sidewall of a tire looks like a periodic wire grating. The performance of an antenna placed close to a wire grating is predicted using Floquet theory. The results indicate that steel plies embedded in the tire can be utilized as a reflector to further focus the gain pattern and increase the read range of a tag. Using these design tools and theoretical analysis, several broadband RFID tag antennas are designed for multi-layered materials. A novel stretchable conductive textile (E-fiber) based tag antenna is also developed for placement in elastic materials. Prototype antennas are fabricated and embedded in a tire during the tire manufacturing process. Experimental results indicate that tags with the new antennas achieve significant improvement compared with commercially available tags.
