Chipless RFID based on RF Encoding Particle
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
Time-Domain Signature Barcodes for Chipless-RFID and Sensing Applications
This book presents an unconventional approach for implementing chipless radiofrequency identification (RFID) systems and related sensors. Contrary to most state-of-the-art chipless-RFID systems, the proposed approach is based on time domain and the tags are read through near field. The book discusses different aspects of these chipless-RFID systems, including tag and reader design, strategies to enhance the data density and capacity, tag programming and erasing, tag implementation in plastic and paper substrates, and synchronous tag reading, among others. A tolerance analysis and validation of the different systems, as well as prospective applications, are also included. The book also offers a comprehensive overview of the state-of-the-art in chipless-RFID technology, including a comparative analysis, which is extended also to chip-based RFID systems. Readers are expected to be familiar with RF/microwave engineering technology. Besides master’s and postgraduate students, the book is intended for researchers in the field of radiofrequency identification (RFID) technology, and may be of interest for engineers working in the areas of wireless communications, automatic identification, security, authentication, microwave and wireless sensors, as well as those dealing with internet of things (IoT) and smart systems.
Chipless RFID Reader Design for Ultra-Wideband Technology
Chipless RFID Reader Design for Ultra-Wideband Technology: Design, Realization and Characterization deals with the efficient design of Field Programmable Gate Array (FPGA) based embedded systems for chipless readers, providing a reading technique based on polarization diversity that is shown with the aim of reading cross-polarized, chipless tags independently from their orientation. This approach is valuable because it does not give any constraint at the tag design level. This book presents the state-of-the-art of chipless RFID systems, also providing useful comparisons. The international regulations that limit the UWB emission are taken into consideration, along with design guidance. Two designed, realized, and characterized reader prototypes are proposed. Sampling noise reduction, reading time, and cost effectiveness are also introduced and taken into consideration. - Presents the design, realization and characterization of chipless RFID readers - Provides concepts that are designed around a FPGA and its internal architecture, along with the phase of optimization - Covers the design of a novel pulse generator
