    • 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.
    • 多光束相位阵列天线装置包括布置在对应的散热器元件(SE1 ... SEm)之后的各个分组中的光束配置装置(BFN)。 在每个组中,光束配置装置(BFN)沿着相关散热器元件后面的第一预定方向一个接一个布置。 根据天线信号的数量(n)选择每个单独组中的波束配置设备的数量。 为每个分组的波束形成装置(BFN)提供信号组合装置(SK)。 用于控制光束配置装置的信号分配装置(VR1 ... VRn)优选安装在用于光束配置装置(BFN)的电路承载基板(SU)的后侧,以提供紧凑的结构。 当每个组的横截面被调整到相关联的散热器元件的面积时,提供了一种特别紧凑和经济的结构。
