Abstract
A multi-beam phase-array antenna device includes beam configuring devices (BFN) arranged in respective separate groups behind corresponding radiator elements (SE1 . . . SEm). In each group the beam configuring devices (BFN) are arranged one after the other along a first predetermined direction behind the associated radiator element. The number of beam configuring devices in each separate group is selected according to the number (n) of antenna signals. A signal combining device (SK) is provided for each separate group of beam forming devices (BFN). Signal distributing devices (VR1 . . . VRn) for control of the beam configuring devices are preferably mounted on the rear side of a circuit-carrying substrate (SU) for the beam configuring devices (BFN), in order to provide a compact structure. An especially compact and economical structure is provided when the transverse cross-section of each group is adjusted to the area of the associated radiator element.
