NOVELTY - The antenna has a conductive layer (10) that is formed with a mesh structure, and another conductive layers (20) are formed with the mesh structure and located on a lower surface of the former layer. An aperture ratio of the layers is 50 percent or more. The former layer includes a rectangular frame shaped edge portion with a predetermined size. Mesh pattern portions are formed at predetermined intervals inside the edge portion. Bridge portions are utilized for connecting the edge portion and the mesh pattern portions. A substrate layer is made of a transparent material, and is made from graphene, carbon nano tubes, carbon nanowires and silver paste. The substrate layer is made of any one material selected from polyimide (PI), polyethylene terephthalate (PET), polymethyl methacrylate (PMMA), and glass. USE - Non-powered transparent antenna for use in wireless communication device. ADVANTAGE - The radio wave shadow area is reduced and eliminated. The radio waves are induced in a specific direction without applying separate power. The antenna is easily attached and used in various indoor and outdoor places where power supply is difficult. DESCRIPTION OF DRAWING(S) - The drawing shows an exploded perspective view of first and second conductive layers of a non-powered transparent antenna. 10,20Conductive layers
