Despite the many benefits of RFID, deployment is still hindered by several factors, both economic and technological. The most limiting factor at this time is the cost of the unit tag. In this book, we focus on the development of chipless RFID tag, which represents a new family of low cost tags. In order to increase the coding capacity of the tag, a new design method based on RCS synthesis is proposed. Although this new approach has been developed in the simplified context of chipless RFID, it can be extended to other domains such as reflect arrays or Frequency selective surfaces. Includes a theoretical presentation of scattering phenomenon in electromagnetism regrouping elements from classical RFID, pulse radar and antenna theoryFeaturing a new coding technique based on magnitude level is presented and characterized for different kinds of tags.For the first time, RCS synthesis based on a physical approach is proposed for a wide frequency band
