Graphene film based Inverted-F Antenna for 5G Mobile Communications

This paper presents an inverted-F antenna based on graphene film for 5G mobile communications. The graphene film has a high conductivity of 1.1×106 S/m. The graphene film based inverted-F antenna with the resonant frequency of 3.48 GHz has excellent performance, which the |S 11 | is -43.2 dB and the bandwidth is from 3.08 GHz to 4.65 GHz.
