Graphene-based dipole antenna for a UHF RFID tag

This paper describes design and measurements of RFID tag built of a graphene-based dipole antenna and a chip operating in the UHF band in accordance with the EPC Global Class 1 Gen. 2 standard. Several tags have been constructed and tested with a standard RFID reader to reveal that each one is fully operational, but the interrogation range for the graphene-based circuits has been limited in comparison to copper antennae. This can be attributed to increased sheet resistance of a graphene layer. However, it seems that for applications were the read range is not crucial the novel antenna can be an alternative to more expensive circuits printed with silver-based inks.
