RFID Tags on Paper Substrate for Bottle Labelling

In this paper we present a possible solution for an RFID tag antenna to be used in bottle labels. To develop this solution we used a transmission line method in order to estimate the permittivity and the dissipation factor of the paper to be used as substrate and also the glass that is present in the bottles. Two prototypes were developed and test were performed with an Alien ALR-8800 RFID reader, with which we demonstrated the proper functioning conditions of the proposed tag and how it surpasses commercially available RFID tags.
