Beamforming networks for antennas have evolved since the 1960’s. Early designs were typically fixed-beam architectures, although newer configurations include complex adaptive beamforming networks. This brief presentation reviews the origins of the technology, and offers several example circuit topologies of passive microwave beamformers.
