PROBLEM TO BE SOLVED: To provide a feed horn for two-satellite reception capable of alleviating a load on development and production, and to provide a converter for receiving satellite broadcasting including the feed horn, and an antenna including the converter. SOLUTION: Bending parts 2a1, 2b1 are included in waveguides 2a, 2b, respectively. A distance between the bending parts 2a1, 2b1 and an axis Z is changed toward outlets (other ends) of waveguides from corresponding horns 1a, 1b. The bending parts 2a1, 2b1 are symmetrically arranged relative to the axis Z and bent so as to be closer to the axis Z toward the outlets of the waveguides from the horns. An interval A between the bending parts 2a1, 2b1 at the outlets of the waveguides is smaller than an interval B. Consequently, the feed horn 1 with the wide interval (interval B) of the horns is connected to a converter at at small interval (interval A) between the waveguides. COPYRIGHT: (C)2007,JPO&INPIT
