ABSTRACT:
A primary radiator includes two horns each having an opening on a larger-diameter side and an opening on a tapered smaller-diameter side opposite to the larger-diameter side, and two corrugated portions provided around the opening on the larger-diameter side of the horn. The outermost corrugated portion is formed to surround all of the horns, and the outermost corrugated portion is formed of one sheet metal member. With this structure, sheet-metal processing can be used to form horns of adaptable shapes and a plurality of horns can be formed at a time.
