DIELECTRIC CORRUGATED HORN AND ITS MANUFACTURE

摘要: PURPOSE:To improve the efficiency of manufacture by laminating a fiber reinforced plastic to inside split die in which desired corrugated groove part is formed for forming horn base material, removing materal from die, and applying Al melt-spray its outer circumferential part. CONSTITUTION:The 5 having 5a at inner wall prepared, dielectric e.g. FRP laminated onto wall, then material 4 4a matching with grooves formed. Then, after separated removed, applied nozzle 6 so as form metallic film outside material. Since leakage an electromagnetic wave penetrating hollow shielded this film, primary radiator function obtained.
