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 taga€™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 a€œspectral signaturea€ technique and is now in its third-generation version with an ultra-wide band (UWB) reader operating at between 5 and 10.7GHz.The vast majority of RFID transponders (or tags) are usually composed of an antenna and integrated circuit (IC). The IC ... Active RFID tags need on-board batteries, have higher cost and can be read even over 100 m. ... of RFID limits their potential for the replacement of trillions of barcodes each year. According to the market analysis of IDTechEx, chipless RFID will occupy more than 60% of the total RFID market by 2018 (in 2009 total market value of RFID exceeded $5 billion).
