FIELD: communication satellite system, used as antenna of fixed-continuous overlapping of the earth surface operating zone. SUBSTANCE: the antenna has a paraboloid reflector and a feeding device that carries horn-dielectric feeds. Arrangement of feeds on the feeding device frame is determined by the shape of the illuminated area. It is possible to select the feed dielectric element with a length within 1.3 to 8λ from the plane of horn aperture, and maximum lateral dimension not exceeding 0.8 to 1,2λ,, which allows it to decrease the distance between elementary feeds, thus increasing the levels of wires intersections. EFFECT: enhanced level of intersection of wires formed by the antenna. |
