PURPOSE:To obtain an inexpensive parabola antenna with high performance, by using an antenna reflecting plate and an insert in forming an antenna main body, forming the main body and the reflecting plate incorporatedly at the same time. CONSTITUTION:A gel coat resin is coated and cured on the surface of an MMD (metal-matched die) forming metallic mold with spraying, brushing or a lancet to form a gel coat layer 1. A carbon fiber 2 is placed on the layer 1, an MMD compound 3 is impregnated to perform compressed forming to form the reflecting plate 4 formed preliminarily. The plate 4 is taken as an insert and placed on an SMC (sheet molding compound) forming metallic mold 5, and an SMC7 is placed further and a metallic mold 6 is tightened. Thus, through the so-called compressed forming, a product 8 having the sectional construction of the parabola antenna is manufactured. |
