Abstract

PURPOSE:To form a horn with excellent electric characteristic efficiently by applying at least maching to a part of a slot whose width and depth are changed gradually and a part including other horn part by die casting, etc., and coupling both the parts. CONSTITUTION:A mode conversion part 11 consists of a circular waveguide 13 connected to a feeding circular waveguide, a part 11a whose slot pitch (p) is constant but whose depth (d) is gradually increased as the width (w) is gradually wider, and a part 11b whose slot width (w) is constant and whose depth only is shallower. Moreover, the horn 12 consists of parts whose slot width (w) and depth (d) are constant. When the mode changes from the circuit waveguide mode into the corrugated waveguide, the part 11a giving much effect on the electric characteristic is manufactured at least by the maching and the part including the horn 12 is manufactured by die casing, etc. Thus, the horn with excellent electric characteristic efficiency is formed.
