3 by 3 phased array controlled by only three phase shifters

In this paper we introduce a new methodology to design beam-forming networks - BFN for phased arrays systems, in which, to scan the beam, is not longer necessary to use a phase shifter for each radiating element conforming the array. The new methodology is based in the coherently periodic radiating structures (CORPS) principles. With the use of this concepts, we can reduce the electronic necessary to scan the beam, e.g., a 3 by 3 antenna array can be scanned using only 3 phase shifters instead 9. By the same way, bigger systems can also be controlled.
