Recent Activities in Rfid Applications Empowered by 3D Printing at UniSalento

RFID continues to offer exciting possibilities for numerous activities, both of mere application of the technology as well as of advanced research. This paper is focused on the research activities developed in the past couple of years at the University of Salento, where RFID technology has been studied since when the UHF band was licensed.In particular, this paper deals with the sole activities linked to 3D printing in RFID, with evidence of recent advances in the state of the art which have enabled, among the others, themes ranging from fully-3D-printed RFID tags, free-form-factor flexible substrates for platform-tolerant tags, and Dielectric Resonator Antennas (DRAs) for higher frequency RFID-inspired backscattering communication.
