Design of a compact, low complexity scalable phased array antenna

A new approach for designing scalable phased array architectures with the main goal of reducing their complexity is proposed. This goal has been accomplished by devising a new technique, based on a vector summation method, to achieve beam steering. In this technique, the number of phase shifters, required in the phased array, are significantly reduced. As a proof of concept, a Ku band eight-element phased array with 40 degrees of scan range is presented. The designed phased array employs only two phase shifters.
