MULTIBEAM ANTENNA Russian patent published in 1997 - IPC

FIELD: antenna equipment, satellite communication. SUBSTANCE: invention is meant for use in satellite communication with increased number of satellites up to 60 in sector. In proposed antenna profile of antenna is manufactured in the form of parabolic torus with relation of focal distance to radius of circumference 0.472-0.474. Excitation sources are mounted for turn in their phase centers from radial direction to center of reflector through angle , where α are angles between radial directions of excitation sources and focal axis; f is focal distance; r is radius of quasi-focal arc. Width of directivity pattern of each of turned excitation source at level of radiation of reflector is equal to sector of correspondence of circumference of reflector to its parabola from proper radial direction. Excitation sources are positioned on brackets. EFFECT: enhanced functional characteristics of multibeam antenna. 3 cl, 2 dwg
