電ホーン。[Claims for Utility Model Registration] (1) A first horn outer conductor on the open end side, a dielectric body having at one end a flange-like part that fills the inside of the first horn outer conductor and is integrally formed; a second horn outer conductor that is connected to the first horn outer conductor by sandwiching the brim-shaped portion of the dielectric; and an airtight packing; A packing groove is provided on the surface where one of the conductors contacts the flanged portion of the dielectric, and the airtight packing is inserted into this packing groove to connect the first horn outer conductor and the second horn outer conductor. A power supply horn characterized by being tightened. (2) The first horn outer conductor is arranged so that the reflected wave from the surface of the dielectric material at the connection portion between the first horn outer conductor and the second horn outer conductor and the reflected wave from the open end are in opposite phases. A power feeding horn according to claim 1 of the utility model registration, which defines the length of the conductor in the axial direction. (3) The flange-shaped portion and the flange-shaped portion are sandwiched between the first horn outer conductor and the second horn outer conductor so that the impedance when looking at the dielectric flange side from the inner surface is close to 0. A power feeding horn according to claim 1 or 2 of the utility model registration claim, which defines the shape of the gap portion.
