HYBRID MULTIPLE-BEAM NON-ATLANTIC MIRROR ANTENNA Russian patent published in 2002 - IPC

Abstract RU 2181519 C1

FIELD: microwave and short-wave antenna engineering for radio communications and observation systems. SUBSTANCE: antenna designed to maintain its characteristics in case of deviation of its partial directivity pattern from focal axis of main reflector through certain angle Θ or in case several deflected partial directivity patterns are shaped due to minimizing quadratic and cubic distortions and astigmatism for each partial directivity pattern by optimal arrangement and orientation of each of feeds shaping partial directivity pattern for feeding antenna array in focal area of main reflector has main mirror made in the from of axisymmetric fragments of paraboloid of revolution with focal length f and aperture diameter D; sub dish; main and radiating antenna arrays composed of set of feeds whose number equals that of partial directivity patterns being shaped; each feed shaping spherical phase front of radiated wave is located in vicinity of respective maximal concentration of beam current reflected from main and additional reflectors of arriving wave with flat phase front whose direction of arrival coincides with orientation of directivity pattern maximum; phase center of each feed is aligned with partial phase center of preceding reflector. EFFECT: reduced loss of antenna directive gain. 3 dwg
