<?Pub Dtl?>Single-feed reflectarrays with asymmetric multiple beams are studied in this paper. The conventional methods for designing multibeam reflectarrays are first reviewed and the limitations of these approaches are delineated for asymmetric designs. A generalized design approach based on a global search optimization technique, namely the particle swarm optimization, is proposed for single-feed...
This paper presents and compares different configurations of several heuristic optimization methods with the aim of seeking the one with the best performance when applied to phase synthesis of reflectarray antennas. This phase synthesis is a hard task and improving the synthesis method can result in significant reductions in the associated computational cost. The performance of algorithms such as...
This paper studies pattern optimization of an offset parabolic reflector antenna with phased array feeds. Considering quantization requirements, to solve optimum weight vector of phased array feeds can be modeled as integer programming problem, which is optimized with the quantum particle swarm optimization (QPSO) algorithm. The optimization with QPSO to determine the quantized element weights is...
