Designing feeding networks with corps: Coherently radiating periodic structures

A new beam-forming network concept is introduced. This network is based in the design principles of CORPS. The new proposed structure presents several improvements in design over the traditional beam-forming network since, with this kind of feed networks, is feasible to reduce of until N times the number of the phase shifters needed to scanning an antenna array. As an example of the application of this technology, a prototype based on Gysel power dividers is fabricated and measured, corroborating the theoretical results and showing an effective scanning angle of more than 20°.
