MANUFACTURE OF PARABOLIC ANTENNA

PURPOSE:To facilitate mass production by receiving an antenna main body in a metallic mould, loading a thin leaf body so that a wave reflecting layer can be fitted on the concave side of the antenna main body, integrating then with vacuum pressing moulding and removing the projecting part of the thin leaf body. CONSTITUTION:An antenna main body 1 and a thin leaf body 5 are separately manufactured and an etching processing is executed to a conductive metallic sheet 3. Then, a wave reflecting layer 3a is formed to be slightly smaller than the concave side area of the antenna main body 1 and after that, the wave reflecting layer 3a is loaded so as to be fitted on the concave side of the antenna main body 1 which is received in a metallic mould 6. Next, the antenna main body 1 and the thin leaf body 5 are integrated by the vacuum pressing moulding and a parabolic antenna is obtained by removing the part of the thin leaf body 5, which is projected out of the edge part of the antenna main body 1. Thus, the parabolic antenna of high quality and satisfactory reliability can easily be mass-produced at a low cost.
