FIELD: physics. ^ SUBSTANCE: double-reflector antenna consists of an emitter, an axially symmetric main reflector, a primary radiator and a conical screen around the edge of the primary reflector, where the axis of the cone coincides with the axial axis of the antenna. Said screen is open on the top part of the edge of the primary reflector. ^ EFFECT: high noise immunity and high noise Q-factor of the reception system with an axially symmetric double-reflector antenna by reducing heat radiation of the ambient medium and hence antenna noise temperature, reduced weight and overall dimensions, reduced blackout area of the main reflector of the antenna. ^ 2 cl, 3 dwg |
