Résumé:
Chipless RFID (Radio Frequency Identification) is a recent technology, based on the use of
completely passive tags with a specific electromagnetic spectral signature, which allows the
identification of the tag. A study and comparison of different reader systems for this type of
chipless tag has been conducted. A specific reader for chipless tags is still commercially
unavailable and the measurements on chipless RFID tags are done using laboratory
equipment. During the internship a chipless RFID reader prototype disposing of a frequency
band going from 3 and 10 GHz has been conceived and partially tested. A particular attention
has been addressed to the compliance to the regulations in effect. A technology watch
concerning the possibility of reusing commercial readers in a modified manner has equally
been conducted. A FMCW (Frequency-Modulated Continuous Wave) Radar has been
acquired for such intent.
