Transparent antenna for display, translucent member for display with an antenna and housing component with an antenna
First Claim
1. A transparent antenna for a display, said antenna comprising:
- an electrically isolated transparent substrate having a surface, said transparent substrate being in planar form so as to form a sheet; and
an antenna pattern formed on said surface of said transparent substrate, and having an electrically conductive section, said electrically conductive section of said antenna pattern including an electrically conductive thin film formed from a first mesh structure and a second mesh structure, said first and second mesh structures being formed from metal wires, each of said metal wires in said first mesh structure being substantially equal in width to each other of said metal wires in said first mesh structure, and a light transmittance of said first mesh structure being 70% or higher,wherein said first mesh structure includes continuous planar meshes on a plane, each of said continuous planar meshes having the same shape and size as each other of said continuous planar meshes, and said second mesh structure forms a distinguishing pattern that distinguishes a part of said antenna pattern, and includes a plurality of meshes, said distinguishing pattern being formed by a linear pattern being disposed on said plurality of meshes in said second mesh structure or bands being disposed on said plurality of meshes in said second mesh structure so as to outline said metal wires in said second mesh structure, the distinguishing pattern decreasing the light quantity passing through said plurality of meshes in said second mesh structure, such that the light quantity passing through said plurality of meshes in said second mesh structure is less than the light quantity passing through said continuous planar meshes in said first mesh structure.

Abstract
A transparent antenna for a display, for example, a portable telephone, the transparent antenna performing good transmission and reception, not bulky, and not impairing design of an apparatus. The transparent antenna for a display has an insulating sheet-like transparent substrate and has a planar antenna pattern formed on the surface of the transparent substrate. An electrically conductive section of the antenna pattern is constructed from an electrically conductive thin film of a mesh structure, outlines of each mesh are constituted from extra fine bands with substantially the same width, and the light transmittance of the section where the antenna pattern is formed is equal to or more than 70%.
