摘要

FIELD: antenna equipment.;SUBSTANCE: invention relates to radio engineering, to the field of antenna technology in the SHF-EHF band and is intended for use in the radio communication systems, radio bearing, radio observing and radio monitoring, for use as part of radio engineering complexes of communication satellites operating in the artificial earth satellites AES at the geostationary earth orbit. Method for creating a multi-beam combined non-axisymmetric mirror antenna consisting of the main mirror (reflector) having the shape of a non-axisymmetric paraboloid cut-out, and of the auxiliary mirror (counter reflector) in the shape of a non-axisymmetric cut-out from the coaxial ellipsoid concave towards the reflector and irradiators that are inclined to the focal axis in the plane, which is orthogonal to this axis, passing through the focus of the counter-reflector, which is made close to the reflector. It contains an additional irradiator in the plane orthogonal to the focal axis and passing through the focus of the counter-reflector, which is made remote from the reflector.;EFFECT: invention can be used in order to transmit and receive television, radio broadcasting and radio communications in the VHF, UHF and SHF bands.;1 cl, 2 dwg
