Novel reflected beam switching method using meta-surface loaded with active elements

In the machine to machine (M2M) propagation environment, beam direction changing technique for small antenna like dipole antenna size is required. We proposed to adopt meta-surface to achieve this instead of reflectarray. However, study of beam switching for meta-surface is not enough despite of important for mobile M2M. To address the issue, this paper proposes novel reflected beam switching method using meta-surface loaded with active elements.
