A fabricated antenna based on highly conductive graphene films is demonstrated with an efficiency averaging 79% over a bandwidth from 3.1 to 10.6 GHz. This is the highest reported value for graphene antennas in the microwave region due to the combination of high conductivity, substantial thickness and efficiency-driven antenna design.
