Patent attributes
An antenna pattern having a broad band characteristic as to frequencies and having a wide directivity, and an electromagnetic wave energy processing device having the antenna pattern, particularly a sheet-like antenna or electromagnetic wave shielding filter. A conductor wire forming the antenna pattern comprises an aggregated wire consisting of mesh or continuously polygonal micro-image element lines or parallel element lines. The element lines are 5-300 μm in line width and 5-1,000 μm in line pitch interval, or the most preferably 5-30 μm in line width and 5-150 μm in line pitch interval. The element lines are printed with printing ink or paste material mixed with conductive powder. In accordance with necessity, pressure treatment or polishing treatment and/or conductive plating with aid of eletroless plating or directly without aid of eletroless plating are performed on the printed surface.
