Design of reconfigurable planar antenna using graphene based switch

This paper presents the design of a reconfigurable planar antenna design using graphene based switch, where its working frequencies can be adjusted by applying different voltages to connect or disconnect four patch sections to a midsection of the planar antenna. The switching comes from the varying chemical potential in the range from 0 to 0.8eV of graphene biased by external voltage. The promising results provide an alternative using graphene in frequency reconfigurable antennas.
