Reflecting plate of circularly polarized wave antenna


PURPOSE:To provide the titled reflecting plate with a radio wave reflecting ability and to hold said ability for a long period by laminating a thermoplastic resin layer having superior weather resistance, a metallic layer reflecting radio waves and polymer layer containing an inorganic filler successively. CONSTITUTION:The thermoplastic resin layer 3 having superior weather resistance, the metallic layer 2 and the olefine group polymer layer 1 are successively laminated. The thickness of the resin layer 3 is 5mu-5mm. and that of the metallic layer 2 is 5mu-1mm.. The thickness of the polymer layer 1 is 500mu-15mm. and the contents of the inorganic filler are 10-80wt%.
