Projeto de antenas e setup para medições de tags RFID sem chip.

Abstract

RFID (Radio Frequency Identification) is a technology that can replace bar code, however, its use is limited by the high price associated with the chip of the tag. In order to make it cheaper, a lot of attention is given to the chipless RFID. Lot of topologies are studied and chipless tag validation often takes place in a anechoic chamber, although there are other types of validation. This work proposes a simple tag, with resonant slot rings, with extra slots to ensure a better spectral codification of the tag.
