Abstract

The microwave transmission properties of printed graphene are studied by measuring different length graphene coplanar wave guides up to 10 GHz and by modelling this behaviour with simple transmission line models. The graphene coplanar wave guide is printed on a PET ST 506 flexible substrates by screen printing method. Vorbeck inks S301 were used in the printing process. 10 and 30 mm long graphene transmission line samples were attached on FR4 test boards and measured. These two graphene lines were modelled with lumped equivalent circuits with scalable parameters. Two equivalent circuit approaches were compared and the high frequency fits suggest that a simple model for graphene conductivity is not sufficient. High frequency behaviour is not possible to model with a bulk conductor but a capacitive path has to be added lowering the high frequency conductivity. This is probably a result of the flake structure of printed graphene.
