The considerable growth of RFID is currently accompanied by the development of numerous identification technologies that complement those already available while seeking to answer new problems. Chipless RFID is one example. The goal is to both significantly reduce the price of the tag and increase the amount of information it contains, in order to compete with the barcode while retaining the benefits of a flexible reading approach based on radio communication. To solve the problem of the number of bits, this book describes the possibility of coding the information at the level of the overall shape of the RCS of the tag, which would facilitate reaching very large quantities. The design of the tags then returns to the resolution of the inverse problem of the electromagnetic signature. The proposed design methodology regularizes the problem by decomposing the signature on a basis of elementary patterns whose signature is chosen in advance. Includes a theoretical presentation of scattering phenomenon in electromagnetism, regrouping elements from classical RFID, pulse radar, and antenna theory Features a new coding technique based on magnitude level that is presented and characterized for different kinds of tags Proposes, for the first time, RCS synthesis based on a physical approach for wide-frequency bands

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: 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

Nanomaterials Design for Sensing Applications examines chemosensors, beginning with molecules that are able to respond to certain stimuli and then showing their assembly and incorporation into sensing materials. The mechanisms of their action for the detection of ions, specific molecules and biostructures, are also covered. A major theme is the affordability of sensors, with particular attention paid to inexpensive and reliable colorimetric sensors that can be read by the naked eye. The book also delves into the development of sensors that utilize existing RFID infrastructure and introduces a novel strategy for the development of self-healing sensing platforms. This book will help readers develop a better understanding of the types of materials used for sensing at the nano level, while also providing an insightful overview on recent advances in this important area. Demonstrates how the use of nanomaterials allows for the creation of cheaper, more reliable sensors Shows how metal oxide nanostructures are used as both sensors and supports for embedded organic and organometallic sensing molecules Explores a novel sensing methodology resulting from the integration of nanostructured sensors into radio frequency identification tags

This book is based on recent research work conducted by the authors dealing with the design and development of active and passive microwave components, integrated circuits and systems. It is divided into seven parts. In the first part comprising the first two chapters, alternative concepts and equations for multiport network analysis and characterization are provided. A thru-only de-embedding technique for accurate on-wafer characterization is introduced. The second part of the book corresponds to the analysis and design of ultra-wideband low- noise amplifiers (LNA).
