NON-INCLINED MULTIBEAM TWO-MIRROR ANTENNA OF IRRADIATED RADIATION Russian patent published in 2018 - IPC H01Q5/00 

FIELD: antenna equipment.

SUBSTANCE: non-inclined multibeam two-mirror antenna of the irradiated radiation consists of a system of irradiators located on the arc of the circumference whose plane is inclined relative to the horizontal plane, main mirror-reflector in the form of a parabola in the plane orthogonal to the plane of arc of arrangement of the irradiators, an auxiliary mirror-counter-reflector in the form of a coaxial parabola of an ellipse concave towards the reflector, sections of which in the plane of arc of irradiators are circumferences concentric to the arc of radiators and having, compared thereto, larger and smaller radii, respectively, the arc of the circumferences of the irradiators passes through the focus of the ellipse, which is close to the reflector. Wherein the forming parabola and the ellipse are asymmetric relative to the arc plane of the irradiator circumference, and the irradiators are inclined to the focal axis.

EFFECT: technical result consists in increasing the efficiency of the antenna while simultaneously transmitting and receiving information from artificial Earth communication satellites located on an inclined part of the geostationary orbit (GSO).
