Abstract

original image

Patterned graphene sheets are fabricated by an inkjet printing technique. High line resolution and sustained electrical conductivity is achieved, and tuning of the sheet resistance is dependent on the concentration of graphene oxide ink and the number of print layers. A patterned graphene-based thin film is also applied as a practical wideband dipole antenna.
