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%.

Transparent antenna for display, translucent member for display with an antenna and housing component with an antenna

A transparent antenna for a vehicle has a transmittance property providing good visibility without worsening the design and is capable of realizing low resistance. The transparent antenna has an insulating sheet-like transparent base body () and an antenna pattern planarly formed on the surface of the transparent base body (). An electrically conductive section () of the antenna pattern is constructed from an electrically conductive thin film of a mesh structure, lines of each mesh are constructed from very fine bands having substantially equal widths, and the width of each of the very fine bands is 30 &#x3bc;m or less. The light transmittance of the antenna pattern is 70% or higher.

Transparent antenna for vehicle and vehicle glass with antenna

A light-transmitting electromagnetic wave-shielding material includes a hydrophilic transparent resin layer laminated on a transparent substrate. An electroless plating layer is laminated on the hydrophilic transparent resin layer in a pattern, and a black pattern section is formed on the hydrophilic transparent resin layer under the electroless plating layer. Therefore, a black electroplating layer is formed to cover the electroless plating layer laminated in a pattern.

Light-transmitting electromagnetic shielding material and method for manufacturing the same

A transparent material for shielding undesired electromagnetic waves, in which a black mesh region is formed in a hydrophilic transparent resin layer on a transparent substrate. The present invention thus provides a transparent material for shielding undesired electromagnetic waves, which comprises:
