The design of a beam-forming network (BFN) for a multibeam-steerable antenna array using Coherently Radiating Periodic Structures (CORPS) is presented. In this design, the input ports of the feeding network are optimized using the particle swarm optimization (PSO) algorithm. A two-beam design configuration of CORPS-BFN for a multibeam-steerable linear array is proposed and analyzed. The results shown in this paper present certain interesting characteristics in the array factor response, in terms of sidelobe level (SLL) and directivity (D), for the scannable multibeam linear array and the feeding network simplification for the design of BFN based on CORPS.

Keywords : CORPS beamforming network; scannable multibeam antenna array; array factor.
