FLAT AERIAL FOR SATELLITE TV Russian patent published in 1994 - IPC

FIELD: aerial equipment. SUBSTANCE: flat aerial is intended for reception of TV signals from satellites. It includes flat decelerating structure above which radiators in the form of parallel equidistant line conductors and exciter in the form of antenna feed (E plane horn) with parabola-cylindric reflector mounted in butt of flat decelerating structure are positioned. Reflector is mounted for rotation about focal axis and ends of line conductors are anchored for translation. EFFECT: improved capability of reaiming of aerial at various satellites without change of its spatial position; approximately 44.2 dB are obtained with efficiency about 58 per cent. 8 dwg
