Abstract
A chipless RFID tag comprises a plurality of disjoint parallel conducting bands formed on a dielectric support, in which conducting bridges interlink neighboring conducting bands, the conducting bridges delimiting, between the conducting bands, portions of dielectric bands of distinct lengths, each portion of dielectric brand determining a resonant frequency of the tag, the set of resonant frequencies of the tag defining an identification code.
