Abstract:
A multi-beam phase-array antenna device comprisinga plurality (m) of radiator elements (SE1 . . . SEm) arranged in a matrix array; a plurality of signal distributing devices (V1 . . . Vn) corresponding in number to the number (n) of beams received during receiving operation or transmitted during transmission operation; beam configuring devices (BFN) for controlling the radiator elements arranged in succession one behind the other in respective separate groups extending in a first predetermined direction behind corresponding individual ones of the radiator elements, wherein the beam configuring devices (BFN) in each of said groups correspond in number to the number (n) of beams received during receiving operation or transmitted during transmission operation; multiplex connection means (KF) for connecting the signal distributing devices (V1 . . . Vn) with the beam configuring devices (BFN); and signal combining means (SK) for directly connecting the beam configuring devices (BFN) in said respective separate groups to the corresponding radiator elements (SE1 . . . SEm) or for connecting the beam configuring devices (BFN) to the corresponding radiator elements (SE1 . . . SEm) by means of amplifying devices (VS1 . . . VSm) and filter devices (FI1 . . . FIm).
