Available in PDF, EPUB and Kindle. Book excerpt: Radio Frequency Identification (RFID) systems are currently a major research area globally. Most of the RFID tags available in the market use application-specific integrated circuits (ASICs) which are expensive compared to other tagging techniques. RFID can only compete with, even and replace barcodes if they are made chipless and printed like the barcodes. Chipless RFID tags reduce the manufacturing costs and enable the use of the technology in high volume applications. Much research has been carried out on the development of chipless RFID tags. However, only a limited amount of work has been carried out on the development of chipless RFID readers.This thesis presents the design of three novel, very low-cost chipless RFID readers for reading spectral signature-based chipless RFID tags. Two of the readers use frequency domain-based techniques to decode data from the chipless tags. The Gen-1 reader is capable of detecting the features of amplitude and phase signature of a chipless RFID tag. The reader requires a calibration measurement. The detection process is more hardware-based and fewer signal processing techniques are used.The Gen-2 reader reconstructs the amplitude and phase responses using the signals received from the chipless RFID tags. The reader does not need a calibration measurement, which offers a major improvement over the predecessors. The voltage controlled oscillator (VCO) of the reader generates a linear chirp (swept) frequency interrogation signal. The Gen-2 reader is even lower-cost compared to the Gen-1 and has a simpler RF section. The detection process uses a Hilbert transform-based signal processing technique to re-construct the amplitude and phase responses of the chipless tag. The operation of both Gen-1 and Gen-2 readers are validated experimentally.The tag reading speed is hindered by the performance of the VCO and the number of data points required in frequency domain-based readers. A novel high-speed tag reading technique based on ultra-wideband RF pulses is proposed in this research. The proposed method is validated with simulations. The integrated reader is a complete system with an RF section, a digital section and a graphical user interface (GUI) and software interface.Most of the existing UWB antenna designs are not suitable for chipless RFID applications due to their low gain or physical size. Hence, in addition to the readers, a design of novel UWB antenna is also proposed in this research work to use with the readers. The antenna is compact and high gain and provides UWB operation with over 9 dB gain and 3.9-10 GHz operating frequency band.The unique features of the developed chipless RFID reader systems are (i) low cost, (ii) secure and (iii) remote and non-line of sight operability. The importance of these developments lies in the fact that they enable the development of low-cost chipless RFID systems comparable to other cheap tagging systems such as optical barcodes.

However, with the advent of low powered ICs, energy scavenging techniques, and low-cost chipless tags, RFID technology has achieved significant development. This book addresses the new reader architecture, presents fundamentals of chipless RFID systems, and covers protocols. It also presents proof-of-concept implementations with potential to replace trillions of barcodes per year. Overall, this resource aims to not only explain the technology, but to make the chipless RFID reader system a viable commercial product for mass deployment. It is certainly a very useful resource in the new field.

This book was released on 2011-12-26 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: This vital new resource offers engineers and researchers a window on important new technology that will supersede the barcode and is destined to change the face of logistics and product data handling. In the last two decades, radio-frequency identification has grown fast, with accelerated take-up of RFID into the mainstream through its adoption by key users such as Wal-Mart, K-Mart and the US Department of Defense. RFID has many potential applications due to its flexibility, capability to operate out of line of sight, and its high data-carrying capacity. Yet despite optimistic projections of a market worth $25 billion by 2018, potential users are concerned about costs and investment returns. Clearly demonstrating the need for a fully printable chipless RFID tag as well as a powerful and efficient reader to assimilate the tag’s data, this book moves on to describe both. Introducing the general concepts in the field including technical data, it then describes how a chipless RFID tag can be made using a planar disc-loaded monopole antenna and an asymmetrical coupled spiral multi-resonator. The tag encodes data via the “spectral signature” technique and is now in its third-generation version with an ultra-wide band (UWB) reader operating at between 5 and 10.7GHz.
Book Synopsis Signal Processing Methods for Chipless RFID by : Prasanna Kalansuriya
Download or read book Signal Processing Methods for Chipless RFID written by Prasanna Kalansuriya and published by . This book was released on 2014 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radio frequency identification (RFID) is a technology that automates routine procedures of data extraction, identification, tracking and surveillance in applications such as inventory control and logistics. The unit cost of conventional RFID tags is too high for them to be used in large item level tagging applications. This is because of the expensive electronic integrated circuits (ICs) used in the tags. As a solution to further reduce the cost of RFID tags, chipless RFID tags have been developed. A chipless RFID tag does not require an IC for its operation.Current research on chipless RFID technology has been focused on, the development of tag designs with enhanced data capacity, the development of tags with sensing capabilities, and the development of RFID reader architectures and signal processing algorithms. Despite current research efforts, further work is required in the area of signal processing for chipless RFID. For this purpose, three novel signal processing methods are introduced in this thesis, (i) development of a robust multidimensional detection algorithm for detecting data bits encoded in a chipless RFID tag, (ii) time and frequency domain analysis of backscattered tag signals for the removal of interference, and (iii) a new systematic calibration procedure for single antenna RFID readers. These methods enhance the performance of chipless RFID systems in terms of the data bit detection and reading range. Existing algorithms used for detecting data bits encoded in a frequency signature of a chipless RFID tag use a one dimensional approach to detection. The one dimensional approach to detection does not consider all the characteristics of the spectral features that encode data bits in a frequency signature. Therefore, the detection performance achieved is suboptimal. In order to enhance the detection performance, a new multidimensional detection method is introduced. The new method utilizes a set of orthonormal basis functions to fully describe the characteristics of a frequency signature. Using these orthonormal basis functions a frequency signature is represented as a signal point in a multidimensional signal space. The detection of data bits contained in an unknown frequency signature is performed using minimum distance detection. It is shown that the performance achieved by the new method exceeds the performance of existing one dimensionalthreshold based detection of tag data bits.The second method proposed in the thesis focuses on improving the reading range of an RFID reader beyond proximity based reading. For this purpose, the total received signal at an RFID reader is analysed in the time domain as well as the frequency domain to identify the essential signal component that contains the tag data. It is shown that the useful data is contained in the antenna mode of the backscattered tag response. The antenna mode backscatter is separated from therest of the received signal using a time window. The separated antenna mode is then analysed in the frequency domain to estimate the tag's frequency signature. Through this time and frequency domain analysis, non-proximity based reading is achieved. It is shown that the tag can be read in non-proximity reading conditions using simulation results and measurements taken in an anechoic chamber environment.The final method introduced in the thesis is a systematic calibration procedure for single antenna based chipless RFID readers. The calibration procedure takes into account practical conditions prevailing in a real world application environment. The calibration allows the RFID reader to accurately estimate the frequency signature of a chipless RFID tag in a cluttered environment. It also addresses the limitations of existing calibration methods used for chipless RFID systems such as the need for repeated calibration and antenna alignment.

Available in PDF, EPUB and Kindle. Book excerpt: Chipless RFID based on RF Encoding Particle: Realization, Coding and Reading System explores the field of chipless identification based on the RF Encoding Particle (REP). The book covers the possibility of collecting information remotely with RF waves (RFID) with totally passive tags without wire, batteries, and chips, and even printed on paper. Despite the many benefits of RFID, deployment is still hindered by several economic and technological factors. Among these barriers are the high cost of tags, lack of reliability and security in the information contained in the RFID chip, and how tags are 'recycled.' This book focuses on the development of chipless RFID tags, representing a new family of low cost tags. With this technology information is extracted from the electromagnetic response of the tag, which depends only on its geometry. Various solutions have been developed by the authors to increase the amount of information, reduce the surface of the tag, or improve the robustness of detection. Considerations such as realization using paper substrate, the development of a low cost detection system, and measurements in a real environment have been addressed for practical implementation. Introduces the chipless RFID REP approach as compared to classical chipless RFID, RFID, and barcode technologies Includes a demonstration of the practical and economic potential of chipless RFID technology, with detailed presentations and discussions of different test benches and comparisons Presents in detail numerous examples of chipless tags that are able to tackle specific problems: sensitivity of detection, encoding density, robustness of detection, problem of tag orientation, tags and reader cost, and compliance with emission standards Focuses on the development of chipless RFID tags, representing a new family of low cost tags

Available in PDF, EPUB and Kindle. Book excerpt: Chipless RFID Authentication examines the development of highly secure product authentication systems for manufactured products by using chipless radio frequency identification (RFID) technology. The absence of a chip and its compatibility with mass production make chipless RFID an alternative to barcodes. This book discusses how, by using natural randomness inherent to the fabrication process, each chipless RFID tag has a unique signature that can never be reproduced, even if someone tries to copy the label. The book first explores the state-of-the-art of existing authentication and anti-counterfeiting methods based on their security level. Next, a methodology describing the characterization of chipless RFID tags for the authentication application is presented, followed by a discussion of the extraction of aspect-independent parameters for chipless RFID tags. After proposing designs for the tags, the book presents the realization and characterization of the labels (which exhibit naturally occurring randomness) for authentication, using printed circuit boards and inkjet printing on polyethylene terephthalate.
