Abstract
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.
