Concepção de um leitor para etiquetas RFID sem Chip.

Abstract

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.
