Abstract

PURPOSE:To improve a return loss characteristic by close-contacting to the large diameter side of a horn antenna where an inner diameter is extended conically, arranging a resin plate with low loss and constituting an off-set parabolic antenna made into a primary radiator. CONSTITUTION:A primary radiator 2 formed by a metallic part 7 has a large diameter input terminal 3 (inner diameter 33mm) and a small diameter output terminal 4 (inner diameter 17.5mm) and an angle is 30-40 deg. in which a horn part is extended. The length of the waveguide of the inner diameter 17.5mm is made arbitrary. The large diameter side is covered with a lid in which the thickness of a resin 6 composed of a polyethylene, polypropylene, etc., with the small loss of an electric wave is 0.5-1mm, and water and dust are prevented. Thus, a satisfactory antenna of a return loss characteristic can be manufactured.
