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