▎ 摘　　要

NOVELTY - The antenna has a graphene patch layer whose four sizes are distributed to a resonant unit. The resonant unit is provided with two rectangular graphene patch and is formed with a gap for loading an excitation source. A graphene material structure layer is provided with four metamaterial structure arrays. Each metamaterial structure array is located at the resonant unit. A meta- material structure array is distributed to multiple graphene square rings. Each column or square ring of each row is provided with a rectangular graphene sheet joint. Each column or each row is loaded with voltage. USE - Graphene-based metamaterial dual-band beam reconfigurable MIMO antenna. ADVANTAGE - The antenna is small size, high stability, easy to integrate. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene-based metamaterial dual-band beam reconfigurable mimo antenna.
