PURPOSE:To improve the radio wave reflecting characteristic of a reflector by applying a conductive paint or the like to a part of a reflector peripheral where no radio wave reflecting element exists so as to expand a radio wave area in forming the antenna reflector. CONSTITUTION:A region where the radio wave reflecting raw material is missing is covered by the electrostatic painting and the coating of a metallic material 7 to expand the ratio wave reflecting face. For example, a conductive paint filled with metallic particles or metallic fibers made of copper, aluminum or nickel is coated as a conductive filler to obtain the conductivity of >=10<3>- 10<5>Scm<-1> after drying thereby forming a conductive layer of serveral tens mum is thickness. |
