Abstract
A beam-forming network having a network of phase shifting devices that is independent from other parts of the beam-forming network. In one embodiment, the network of phase shifting devices has multiple layers between the power divider and power combiner layers. The multiple layers provide a selectable phase shift for each feed independent from the other feeds. In another embodiment, the network of phase shifting devices is one layer of commendable phase shifters. In any embodiment, the resulting composite beam has higher directivity and lower side lobes as compared to conventional beam-forming networks.
