SHEET ANTENNA

PROBLEM TO BE SOLVED: To provide a sheet antenna by which an antenna element of an antenna used by being stuck to transparent glass is difficult to be visually recognized, visibility and appearance of the transparent glass are not spoiled. SOLUTION: In the sheet antenna 10, an antenna constituted by forming an antenna element 11 by a conductor is formed and the antenna element 11 is formed by aggregate of thin-line shaped conductors 7 in the state where conduction from the tip part to the base part of the antenna element 11 is secured on a dielectric sheet 19 attached to a part constituted of a transparent dielectric. The thin-line conductors 7 are arranged like meshes or in parallel at intervals of about 200 μm. made into the aggregate and line width of the thin-line conductor 7 is considered as about 1/100 of the line width of the antenna element 11.
