MULTIBEAM SINGLE-REFLECTOR ANTENNA FOR RECEIVING SIGNALS FROM SATELLITES ON EDGE OF VISIBLE GEOSTATIONARY ORBIT SECTOR

摘要

FIELD: physics.;SUBSTANCE: disclosed is a multi-beam antenna, having a reflector which is a cut of a portion of a surface formed by turning a parabola about an axis lying in the plane of the parabola and perpendicular to the focal axis of the parabola, and a line or radiators lying on the middle of the radius of rotation and at the focal point of the parabola. Said portion is cut from a surface formed by turning a parabola about an axis inclined at an angle equal to the angle of inclination of serviced section of the geostationary orbit to the horizon line, to the normal to the plane passing through the point where the antenna is located and two points lying infinitely near to centre of the serviced section of the geostationary orbit such that the top and bottom edges of the reflector lie in parallel to said plane, and the line of radiators is inclined to said plane.;EFFECT: high gain of the multibeam single-reflector antenna which is specifically meant to receive signals from satellites located on the edge of the visible section of the geostationary orbit, which does not need to be inclined to the earth's surface.;5 dwg
