FLAT ANTENNA ARRAY AND DRIVING ELEMENT FOR FLAT ANTENNA ARRAY Russian patent published in 2001 - IPC

FIELD: reception of satellite television signals. SUBSTANCE: flat antenna array has dielectric cover plate with reflectors, each coming in the form of family of conducting lands, conducting plate with assemblage of radiating holes, dielectric plate and screening plate arranged in the form of multilayer structure to form microstrip radiators with driving elements. The latter have at least one output of signals of preset polarization and one power supply system to feed microstrip radiators as minimum. Dielectric cover plate carries partitions forming cells to separate one reflector from another. Partitions are made as one unit with dielectric cover plate and have conducting coat. Driving element for flat antenna array has two orthogonal sondes and conducting land located perpendicular to bisector of right angle included between them positioned on dielectric plate. Conducting land is conductively coupled to orthogonal sondes. EFFECT: provision for reception/transmission of signals of various polarization with high gain factor, simplified and reliable structure of antenna array and its high adaptability to manufacture. 15 cl, 10 dwg
