Abstract
A phase shifter assembly for use with a phased array antenna includes a plurality of phase shifter subarrays which are mounted on a ferri-magnetic substrate. There is a common power feed which is connected in series through a transmission line with each of the phase shifter subarrays. Additionally, a plurality of power combiners/splitters are connected into the transmission line to direct the proportionate power to each subarray. An alignment phase shifter is connected into the transmission line between adjacent subarrays and their associated power combiner/splitter. Separately from the transmission line, a driver is electronically connected in series with coils at each of the alignment phase shifters to alter the phase power which is fed into each of the subarray to align adjacent subarrays and produce a substantially continuous wave for the antenna. There is also a common driver which is electronically connected in series with each of the phase shifter subarrays to alter the phase of the power which is fed from the common power feed to the radiating elements of the antenna and thereby establish the direction of the radiated beam.
