Trends in the design of RFID tags

This communication is mainly dedicated to the design of RFID tags, in particular the antennas that allow the tag to be fed, communicate and exchange data with the reader. Good performance tags require optimized antenna that take into account numerous constraints as well as the environment of the application under consideration. Conventional tags based on IC chips as well as chipless or RF barccode are discussed. The last part of the communication will consider how to transform a tag into an RFID sensor thanks to a specific modification and accurate design of the tag antenna.
