    • A beamformer is arranged to receive an input from a first antenna element and from at least one other antenna element and to generate at least a first and second output beam. The first and second output beams are combined at a connecting port such that signals received at the first antenna element are constructively combined at the connecting port and signals received at another antenna element or elements are destructively combined at the connecting port, so that a receiver connected to the connecting port may receive signals from the first antenna element and may not receive signals from the other antenna element or elements. The arrangement may also be used to transmit a signal which is fed into the connecting point from the first antenna element and not from the other antenna element or elements.
    • 波束形成器布置成从第一天线元件和至少一个其它天线元件接收输入并且产生至少第一和第二输出光束。 第一和第二输出光束在连接端口处组合,使得在第一天线元件处接收的信号在连接端口被建设性组合,并且在另一个天线元件处接收的信号在连接端口被破坏性组合,使得接收器连接 连接端口可以从第一天线元件接收信号,并且可能不接收来自其它天线元件的信号。 该装置还可以用于从第一天线元件而不是从另一个天线元件发送馈送到连接点的信号。
