Abstract:
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 (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 equal widths, 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.
