ABSTRACT:
A beam-steering feed network for use with linear and planar phased-array enna systems which includes a phase divider system for producing a plurality of incrementally phased IF signals. The phase divider system includes a plurality of coupled amplifier phase divider modules coupled together to form a network. The network is coupled to receive at least two boundary signals having different phase angles. The phase angle difference between the boundary signals is divided by the phase divider modules in the network. Each module produces an output signal having a phase angle differing from that of the output signals of the immediately adjacent modules in the network by a phase angle gradient. The system thus divides the phase angle difference between the boundary signals into a plurality of incrementally phased output signals.
