Abstract:
A system for providing adjustable elevation scanning per antenna beam of a multibeam phased array, wherein said phased array includes a plurality of antenna elements divisible as an upper sub-group and a lower sub-group, said system comprising:first means for coupling a first signal path to said upper sub-group of antenna elements and to said lower sub-group of antenna elements, wherein said first coupling means provides a first phase differential between signals associated with said upper and lower sub-groups of antenna elements, and wherein said first signal path is associated with a first antenna beam of said multibeam phased array; andsecond means for coupling a second signal path to said upper sub-group of antenna elements and to said lower sub-group of antenna elements, wherein said second coupling means provides a second phase differential between signals associated with said upper and lower sub-groups of antenna elements, and wherein said second signal path is associated with a second antenna beam of said multibeam phased array.
