Abstract:
A transparent antenna for a display for, 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 (1) for a display has an insulating sheet-like transparent base body (1a) and has a planar antenna pattern formed on the surface of the transparent base body (1a). An electrically conductive section (1b) of the antenna pattern is constructed from an electrically conductive thin film of a net structure, lines defining each mesh are constructed from very fine bands with substantially the same width, and the light ray transmissivity of the section where the antenna pattern is formed is equal to or more than 70%.
Abstract:
A transparent antenna for a vehicle, having transmittance property providing good visibility without worsening design and capable of realizing low resistance. The transparent antenna has an insulating sheet-like transparent base body (1a) and an antenna pattern planarly formed on the surface of the transparent base body (1a). An electrically conductive section (1b) 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 the equal width, and the width of each of the very fine bands is 30 µm or less. The light transmittance of the antenna pattern is 70% or higher.

PROBLEM TO BE SOLVED: To provide a touch input sheet high in yield and productivity capable of obtaining the touch input sheet having each circuit pattern in an accurate position, and a manufacturing method therefor. SOLUTION: The touch input sheet includes circuit patterns of transparent conductive film in a central window on a transparent base sheet and thin-line lead circuit patterns formed of transparent conductive films and conductive print films successively laminated on an outer frame line portion. The circuit patterns of the transparent conductive film are formed at predetermined places. The transparent conductive film and the conductive print film of the thin-line lead circuit patterns are formed in lamination with an identical pattern at predetermined places without causing position deviation. In the touch input sheet and the manufacturing method therefor, the circuit patterns of the transparent conductive film and the thin-line lead circuit patterns are formed at both sides of the base sheet with an alignment mark formed on either side thereof.
