ACTIVE-ARRAY MULTI-BEAM ANTENNA COMPRISING A HYBRID DEVICE FOR FORMING DIRECTIVE BEAMS

An active-array multi-beam antenna includes radiating elements and a hybrid device for forming directive beams. The hybrid device comprises an analogue stage divided into a plurality of analogue beam-forming networks forming like regional beams, and a digital stage suitable for forming the directive beams from the regional beams. A first sub-array is associated with first radiating elements. A second sub-array is associated with second radiating elements. The second sub-array has the same dimensions as the first sub-array. The second sub-array partially overlaps the first sub-array.
