Abstract

A multi-beam-former for an antenna array is described, the multi-beam former comprises N transceiver terminals for connecting a transmitter and/or receiver and N antenna terminals for connecting to a respective antenna and a plurality of couplers and matrix phase shifters arranged in an NxN Butler matrix configuration between the N transceiver terminals and the N antenna terminals. At least some of the matrix phase shifters include a switchable matrix phase shifter configured to switch between a respective first phase shift value and a respective second phase shift value; a plurality of bypassable phase shifters arranged between at least some of the couplers and the antenna terminals and configured to switch between a respective further phase shift value and a zero phase shift. The multi-beam former Is operable to select one of M different beam angles for a signal, wherein M is greater than N.
