PURPOSE:To achieve light weight, b enabling to fold the antenna like paper for storing and transporting, by forming a thin metal layer on insulation sheet in conforming with the shape of the antenna. CONSTITUTION:By using a laminated paper of a metal such as aluminum and an insulation sheet 1 like plastic sheet, the metal part is etched to an antenna pattern to form a thin metal layer 2 in conforming with the shape of the antenna. A conductor 3 is led out from a part of the thin layer 2. Thus, the antenna is made small by folding and is made suitable size to the wave length when it is spread. |
