ンバータとから成るパラボラアンテナ装置。 A reflector of a parabolic antenna that receives and reflects microwaves, a circular-to-linear converter corresponding to circularly polarized waves of the microwave, and a first rectangular waveguide adjacent to the rear end of the circular-to-linear converter. A first tube consisting of
a second feedhorn comprising a concentrator corresponding to the linearly polarized wave of the microwave and a second rectangular waveguide whose rear end protrudes inward; and a third rectangular waveguide that communicates with the second rectangular waveguide, and an input terminal, and the tip of the input terminal connects the first rectangular waveguide to the second rectangular waveguide. 3. A parabolic antenna device comprising a converter located inside any one of the rectangular waveguides of No. 3, which takes in microwaves passing through the first feedhorn or the second feedhorn and converts them into an intermediate frequency signal.
