FIELD: communications.
SUBSTANCE: invention relates to a single-beam antenna device circuit. To this end the antenna device comprises a reflector that forms an offset antenna with a cut segment of a paraboloid of revolution, and a primary radiator, which emits a beam having an elliptical cone shape on the plane of the aperture reflector. Contour of the reflector plane of the aperture of the reflector is formed in an elliptical shape along the isolux elliptical beam emitted from the primary emitter. Accordingly, due to the lost power by the illuminator intercept mirror reflector offset in space, wherein the reflector circuit of the present embodiment acts as a reflector of the conventional circuit having a vertical elliptical shape formed perpendicular to the axis of the beam incident on the aperture plane of the reflector. In the space, in which loop a conventional reflector protrudes from the contour of the reflector of the present embodiment, deterioration in efficiency is compensated by the irradiation of the reflector.
EFFECT: technical result - a small power illuminator does not intercept the mirror due to the effectiveness of radiation reflector and low sidelobe performance.
