Fabrication and performance evaluation of 3D-printed graphene passive UHF RFID tags on cardboard

This paper discusses the fabrication and wireless performance of 3D-printed graphene-based passive UHF (ultra high frequency) RFID (radiofrequency identification) tags on two different cardboard packaging substrates. Our results confirm that the low-cost and eco-friendly graphene-based RFID tags achieve high performance with attainable read ranges of 3.2-3.8 meters. These results are superior to those of previously reported RFID tags with graphene antennas.
