FIELD: radio engineering, communication.
SUBSTANCE: antenna consists of an axisymmetric primary mirror-reflector having the shape of a paraboloid and an auxiliary mirror-counter-reflector in the form of a coaxial ellipsoid concave towards the reflector, and irradiators in a plane orthogonal to the focal axis and passing through the focus of the counter-reflector, close to the reflector. Herewith one or more irradiators are additionally installed in a plane orthogonal to the focal axis passing through the focus of the counter-reflector remote from the reflector.
EFFECT: increasing the efficiency of antenna while simultaneous receiving two frequency bands.
