Chipless RFID, an emerging technology

International audienceRadiofrequency identification (RFID) is an established technique for automatic data captures exploiting reflected electromagnetic waves by scatters, usually called tags or transponders. In the last decades, roughly since the mid-1960s, very effective integrated circuit-based tags have been developed and implemented in numerous applications from the most simple like the electronic surveillance article to the more sophisticated like the Internet of Things. Even if conventional RFID is a well developed and broadly used technology worldwide, the need for an all-passive solution is highly desirable for certain applications that require low-cost, mechanical robustness and ability to be implemented in severe environments
