Design of a coplanar graphene-based nano-patch antenna for microwave application

We analyze a coplanar graphene-based nano-patch antenna. Besides the fact that graphene is a moderate conductor at those frequencies, the antenna can still exhibit sharp resonances. Although the poor graphene conductivity implies in general low-performance, a remarkable change of the scattering parameters, radiation pattern and antenna efficiency can be observed as the graphene surface impedance is changed by means of an external Bias.
