摘要： The invention relates to a chipless RFID tag (51) comprising a plurality of disjoint parallel conducting bands (55) formed on a dielectric support (53), in which conducting bridges (58) interlink neighbouring conducting bands, the conducting bridges delimiting, between the conducting bands, portions of dielectric bands (59) of distinct lengths, each portion of dielectric band determining a resonant frequency of the tag, the set of resonant frequencies of the tag defining an identification code.
