Book excerpt: Avui dia, la identificació automàtica i unívoca d'objectes s'està imposant com a necessitat creixent a nivell global, degut al ràpid increment de la producció i del comerç mundial. En resposta, la identificació per radiofreqüència (RFID) està emergint com una alternativa viable i més evolucionada al codi de barres, i està sent utilitzada en una multitud d'aplicacions diferents, tal com el seguiment de paquets, els inventaris intel·ligents, el control d'accessos i el pagament sense contacte. Encara que la tecnologia RFID ha aconseguit entrar amb èxit en la nostra vida diària, oferint una solució convenient en moltes aplicacions, existeixen alguns reptes que estan frenant la seva difusió. Per exemple, l'etiquetatge de petits objectes metàl·lics necessita de més recerca, per tal d'obtenir etiquetes RFID més primes i petites, donat que actualment les etiquetes RFID per metall són més gruixudes i més cares que les etiquetes RFID convencionals. El disseny d'etiquetes RFID miniaturitzades amb una resposta independent de l'orientació és també un problema encara pendent. En altres casos, el context d'etiquetatge requereix maximitzar la distancia de lectura, encara que això impliqui augmentar les dimensions de l'etiqueta. Per tant, el disseny d'etiquetes RFID d'alta distancia de lectura és un altre repte interessant en la investigació sobre la tecnologia RFID. L'objectiu principal d'aquesta tesi és la recerca de solucions pràctiques als problemes mencionats, que contribueixin al desenvolupament de la tecnologia RFID, així com a la seva ulterior difusió en les aplicacions de la vida diària. En concret, aquest treball es focalitza en el disseny d'antenes per etiquetes passives de RFID a la banda UHF basades en ressonadors inspirats en el món dels metamaterials (ressonadors d'anells oberts i estructures derivades) com a elements radiants, explorant també solucions alternatives basades en altres estructures ressonants.

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.

This was followed immediately with a discussion on metamaterials and LH-propagation. Expressions for the propagation constants, phase velocity and Bloch impedance were derived and discussed. Next, several metamaterial-based antenna designs for passive RFID tags were presented. The designs offered showed that by incorporating elements found in metamaterials in the design of the antenna on a RFID tag, the antenna could be made to resonate at a much smaller dimension. The result is a compact passive RFID tag with very useful max read range values.

Available in PDF, EPUB and Kindle. Book excerpt: Radio frequency identification (RFID) is an auto-identification technology realised by radio waves. The ultimate goal of RFID is the item-level tagging of all kinds of products in supply chains. This goal challenges industry and academia in many aspects. Passive UHF RFID systems, when compared with other RFID systems, are believed to possess advantages in achieving that goal. However, UHF RFID systems possess two serious disadvantages: (i) the relatively large antenna size, and (ii) the sensitiveness to the metallic items on which a tag is mounted. Those two deficiencies make a large number of small size objects and metallic objects hard to tag. In addition, different applications also bring special requirements or limitations in adopting UHF RFID systems, such as in the case of a container seal, the requirement for tags to have a physical security function, and in other cases such as pallet shipping, the requirement for detecting massive numbers of items densely stacked together. Finally, of course, cost is one of the key limitations if one intends to apply his or her design down to item-level tagging commercially. Hence each of the inherent deficiencies of the system itself and the limitations caused by the application, or a combination of all or some of the deficiencies and limitations make a large number of items hard to tag and impedes the item-level tagging target. The research in this thesis aims, by antenna design and electromagnetic wave analysis, to provide feasible and affordable solutions for some of those hard-to-tag objects in UHF RFID systems, and the thesis can be divided into five parts. In detail, the first part of the thesis gives the motivations, contributions and structure of this thesis. In addition it also provides a brief introduction to RFID systems and about how they are operated, developed, classified, regulated and standardised. The second part of this thesis presents basic terminologies and design criteria in tag antenna design, transponder IC design and reader design. Factors which limit the operating range of UHF RFID systems are discussed. Following this discussion, a novel method making use of a scattering matrix for evaluating the operating range of a UHF RFID system deployed in an arbitrary environment is proposed. In the third part, concerning the meander line dipole antenna (MDA), one of the approaches to minimising tag antenna size is analysed in terms of its resonant frequency, size reduction contributors, radiation pattern and efficiency. An analytic formula for calculating the resonant frequency of an MDA on a dielectric substrate as an RFID tag antenna is established. Based on the analysis, a novel tag antenna with a physical security function (an electronic seal) for protecting shipping containers was designed and experimentally verified. The fourth part of this thesis puts emphasis on metallic item detection. The reason of why common dipole based tag antennas cannot work well in close proximity to metal is given. Previous solutions and their own demerits in solving this problem are summarised. Then, a low profile, simple structure, compact size solution is introduced via the artificial magnetic conductor concept. Furthermore, a general DVD disc contains a very thin metal layer inside for the purpose of reflecting laser. That layer may not bring many troubles in identifying a single DVD by a UHF RFID system, but if thousands of DVDs were stacked, the role the metal component plays in degrading the detection of each DVD in the stack should be investigated. An approach in detecting a large number of DVDs (up to 2000) densely stacked is thus presented. Conclusions of the work in this thesis are drawn as the last part of the thesis. Besides conclusions the last part also includes some recommendations for future work and the description of the original contributions of this thesis. The potential benefits of item-level tagging in supply chains are enormous. The existence of a large number of hard-to-tag objects is one of the main challenges in achieving item-level tagging. The studies in this thesis extend the scope of the detectable objects and this extension makes item-level tagging more realisable.

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.
