MULTIPLE-BEAM MIRROR ANTENNA Russian patent published in 1997 - IPC

FIELD: satellite communication, in particular, antennas for continuous overlap of monitored area of earth surface. SUBSTANCE: device has parabolic mirror 1 and emitter 2, on which funnel dielectric elementary elements are located. position of emitters on frame of emitting device is determined by shape of monitored area. Device provides possibility to decrease distance between elementary distance by selection of dielectric element 5 of emitter which length is in range of 1.3-8 $$$ of area of funnel 3 and which maximal cross section is not greater than 0.8-1.2 $$$. EFFECT: increased level of beam intersection. 1 dwg
