Antenna system with distortion compensating reflectors
Abstract
Abstract D R A W I N G AN ANTENNA SYSTEM HAS A REFLECTOR SYSTEM COMPRISING A PLURALITY OF REFLECTORS HAVING ROTATIONALLY ASYMMETRICAL CURVED SURFACES SUCH AS ELLIPTIC, HYPERBOLIC OR PARABOLIC SURFACE GEOMETRIES. IN ORDER TO COMPENSATE FOR THE ASYMMETRICAL PROPERTIES OF THE REFLECTORS, AT LEAST ONE PAIR OF ASYMMETRICAL REFLECTORS IS ARRANGED IN FACING RELATIONSHIP SO THAT THE DIFFERENCES IN ASYMMETRICAL PROPERTIES ARE COMPENSATED BY THE OPPOSITE RADIATION DISTRIBUTION CHARACTERISTICS OF EACH REFLECTOR. THE REFLECTORS ARE POSITIONED APART SO THAT AMONG THE REFLECTORS THE RATIO BETWEEN THE PRODUCT OF THE DISTANCES FROM EACH REFLECTION POINT OF EACH REFLECTOR TO THE FOCUS OF EACH REFLECTED BEAM FORMS A CONSTANT RATIO WITH THE PRODUCT OF THE DISTANCE FROM THE REFLECTION POINT TO THE FOCUS OF EACH INCIDENT BEAM. ACCORDINGLY, WHEN AN ELECTROMAGNETIC BEAM SOURCE WITH A ROTATIONALLY SYMMETRICAL BEAM, IS APPLIED, A ROTATIONALLY SYMMETRICAL RADIATION DISTRIBUTION CHARACTERISTIC RESULTS AT AN APERTURE OF THE ANTENNA SYSTEM EVEN THOUGH THE REFLECTORS HAVE ROTATIONALLY ASYMMETRICAL CURVED SURFACES.
