Investigation of Graphene Film-based Circular Monopole Antenna for UWB Applications

Graphene film based circular shaped monopole antennas with ultra- wideband (UWB) performance is presented. Proposed antennas consist of a circular patch radiator made by graphene films and a ground plane made by copper and graphene film, respectively. This proposed nonmetal antenna can achieve a bandwidth of120% and covers the frequency range from 2.5 to 10.5 GHz for a return loss greater than 10 dB. In addition, the antenna is implemented and experimental results are in good agreement with the simulated ones.
