MULTIBEAM LENS ANTENNA Russian patent published in 1997 - IPC

FIELD: antenna engineering. SUBSTANCE: antenna has central-symmetry spherical lens secured by fastenings on elliptical frame so that center of lens is beyond frame plane. The latter is mounted on base for turning relative to horizontal plane. Antenna also has feeds placed in semi-ring guide joined to frame through fastenings. Lens and guide fastenings are self- aligned in angular position and self-adjusted for displacement along their axes. Semi-ring guide is mounted in plane parallel to that crossing center of lens and long axis of frame; the latter is mounted on adjustable base for turning statically balanced lenses, frame, and semi-ring guide relative to long symmetry axis of frame followed by locking frame in position. EFFECT: improved design. 5 cl, 5 dwg
