▎ 摘　　要

NOVELTY - Three-dimensional graphene antenna comprises a three-dimensional graphene radiation layer (1), a medium substrate (3), a metal layer (4) and a feeder line (2). The medium substrate is tightly provided with a three-dimensional graphene radiation layer. The medium substrate is connected to one side of the three-dimensional graphene radiation layer through a feeder line. The lower part of the medium substrate is tightly adhered with a metal layer. USE - The antenna is useful in the fields of electronics, information, materials and energy. ADVANTAGE - The method: is simple and easy to implement; has high efficiency and energy saving. The graphene has a porous conductive network structure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the three-dimensional graphene antenna. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the three-dimensional graphene antenna for electronics, information, materials and energy.
