Abstract
Techniques for the design of low cost, low complexity phased arrays are described. The techniques allow control of the phase progression in the entire phased array by using only one phase shifter for a bank of arrays. In some examples, the phased array includes directional couplers, amplifying stages, power combiners and a phase shifter. The phase shifter may be of various kinds, including simple and compact phase shifters formed of varactor diodes and inductors or transmission lines.
