“…The RLUAA, the first model optimized in [10], consists of 100 elements distributed arbitrarily on an aperture of 4.5λ × 4.5λ, in which the minimum element distance d min was 0.4λ and the inception angle was θ 0 = 0.201. The optimization of the SUACRA is carried out for the same transmitting aperture and the same inception angle, which is denoted by SUACRA 1.…”

“…The design and implementation of transmitting array could be greatly simplified if all elements are uniformly excited [9]. The random-located uniformamplitude array (RLUAA) comprising of 100 elements was optimized by particle swarm optimization (PSO) algorithm with a BCE of 89.96% being obtained [10]. However, the computation amount would grow up rapidly as the element number increases, which could not be applied in a largescale transmitting array design.…”

Beam capture efficiency (BCE) is one key factor of the overall efficiency for a microwave power transmission (MPT) system, while sparsification of a large-scale transmitting array has a practical significance. If all elements of the transmitting array are excited uniformly, the fabrication, maintenance, and feed network design would be greatly simplified. This paper describes the synthesis method of the sparse uniform-amplitude transmitting array with concentric ring layout using particle swarm optimization (PSO) algorithm while keeping a higher BCE. Based on this method, uniform exciting strategy, reduced number of elements, and a higher BCE are achieved simultaneously for optimal MPT. The numerical results of the sparse uniform-amplitude concentric ring arrays (SUACRAs) optimized by the proposed method are compared with those of the random-located uniform-amplitude array (RLUAA) and the stepped-amplitude array (SAA), both being reported in the literatures for the maximum BCE. Compared to the RLUAA, the SUACRA saves 32% elements with a 1.1% higher BCE. While compared to the SAA, the SUACRA saves 29.1% elements with a bit higher BCE. The proposed SUACRAs have higher BCEs, simple array arrangement and feed network, and could be used as the transmitting array for a large-scale MPT system.

Multi-port multi-mode antenna elements have the ability to move their phase centers and modify their radiation patterns electronically. Arrays composed of such elements are referred to as virtually aperiodic arrays in this paper. Herein, optimization of the mode excitation coefficients in virtually aperiodic sparse linear arrays is proposed, by introducing novel design constraints with the aim of synthesizing wide-angle scanning, reconfigurable patterns, with grating/side lobe reduction. A dual-mode patch antenna is used for demonstration purposes. An efficient convex optimization based algorithm is adopted to optimize the excitation weight at each element mode port, while considering the mutual coupling effects. Through full-wave simulations, the effectiveness of the optimization in suppressing the unwanted radiation and adapting to different fields-of-view is shown. A novel investigation on the impacts of defining different mode excitation ratios on the radiation pattern characteristics is conducted.

This letter presents a large spacing nonuniform distribution, uniform excitation sparse square array model to maximize beam collection efficiency (BCE) and minimize sidelobe level outside the collection area (CSL) of the transmitting antenna in microwave wireless power transmission (MWPT) systems. We improve the position update parameters in the dynamic weight particle swarm optimization (DWPSO) algorithm by adding multiobjective learning features (MODWPSO). We use MODWPSO to optimize the elements' positions to maximize BCE and minimize CSL and discuss the effect of the minimum element spacing value on BCE and CSL. By comparing the array performance with a typical array model, it can be concluded that the proposed large spacing sparse nonuniform distribution, uniform excitation square array model has higher BCE, lower CSL, and fewer costs.
