Abstract
This chapter focuses on the principal developments in chipless technology that have occurred at the Laboratory of Conception and Integration of Systems (LCIS) since 2009. It discusses one of the basic issues of chipless radio frequency identification (RFID) technology: its storage capacity for recording the identifier. The coding capacity of chipless RFID tags has been at the heart of the chipless issue. Coding capacity also depends on: the intrinsic performance of the resonators used, the technique used to code the information and the development of a reader which, among other aspects, must comply with effective transmission and reception norms. The chapter now focuses on the question of improving reading in a real usage environment. It considers the case of REP frequential tags. The chapter presents the latest aspects that have led to the realization of a portable demonstrator, able to read the tags produced in a real usage environment.
