ーンアンテナ。 In a horn antenna that is shared by two frequency bands and is configured by connecting a conical horn, a plurality of circular waveguides each having an iris loaded therein, and a plurality of circular tapered waveguides having different taper angles, a conical horn; It is constructed by connecting two circular waveguides each loaded with two irises and two tapered waveguides, and the inner diameter of the circular waveguide loaded with the first iris from the horn opening is set to the low frequency band. , the diameter at which the TM11 mode is not cut off in both frequency bands in the high frequency band, and the inner diameter of the circular waveguide loaded with the second iris from the horn opening. A horn antenna characterized in that the iris has a diameter that does not cause cut-off, and the iris is dimensioned so that the frequency differential value of the amount of higher-order modes generated becomes zero.
