“…It is obvious that CPSO algorithm outperforms PSO algorithm, and less than 500 iterations are needed for the CPSO to converge to its final value. To further compare their performance, the problem presented in [11] is solved by the CPSO algorithm, and CSL constraint is added. Higher BCE and lower CSL can be obtained, which further shows the superior of the CPSO algorithm.…”

This paper describes a synthesis method of uniformly excited unequally spaced planar array with maximum beam collection efficiency (BCE) based on Chaotic Particle Swarm Optimization (CPSO) algorithm. And here the multiple optimization constrains include the number of array elements, the aperture, the minimum element spacing, and the maximum sidelobe level (SLL) outside the receiving region. Through this method, feeding network of the array becomes simple and compact. Effectiveness of the proposed method is validated by comparing the simulation results obtained in this paper to those reported in the state-of-the-art literature.Index Terms-Antenna arrays, microwave power transmission, chaotic particle swarm optimization, solar power satellite.

“…However, energy radiation capacity of the power beam is improved without considering the energy cost of each node. In Li et al, 32 a PSO-based optimization algorithm for WPT is presented. The improvement of the energy collection efficiency in the power pattern is achieved by optimizing the node spacing, but the node weight is not optimal.…”

A group of collaborative nodes can efficiently complete spatial long-distance transmission tasks using beamforming technology. However, a high sidelobe level interferes with communication quality, and uneven energy consumption of nodes affects network lifetime. This paper proposes an energy-efficient collaborative transmission algorithm based on potential game theory for beamforming. First, the minimum number of cooperative nodes is determined in accordance with the energy consumption and spacing limitation condition. A group of nodes satisfying the node spacing condition is selected as cooperative nodes based on the ring array to minimize communication interference among nodes. Second, a potential game model is proposed as a joint method for optimizing the collaborative parameters of the cooperative nodes and their energy consumption balancing features. Finally, the game process is continuously executed until the Nash equilibrium is reached. According to simulation results, the sidelobe level caused by the cooperative nodes is reduced and the transmission conflicts are lessened. Thus, the quality of communication links in between nodes in the network is improved. Energy efficiency is also promoted because a balancing of energy consumption is involved in the proposed potential game model, and network lifetime is effectively prolonged accordingly.

“…Two important factors that are the transmission distance and the energy efficiency should be considered in the RF-based WPT system [1]. Thus, to enhance the transmission distance while keeping a certain level receiving efficiency has been taken into account [5]. For improving the receiving efficiency, most current research commit to improve the RF-to-DC conversion efficiency of the receiving antenna.…”

The power pattern synthesis, as well as the sidelobe level (SLL) suppression of the planar antenna arrays for the wireless power transmission is investigated. An improved chicken swarm optimization (ICSO) algorithm is proposed for reducing the maximum SLL of the power pattern. ICSO introduces the global search, the local search, and the duplicate solution removing operators to enhance the accuracy and the convergence rate of the conventional CSO algorithm, thereby making it suitable for the power pattern optimizations. Simulations are conducted to verify the performance of the proposed algorithm, and the results show that ICSO obtains the lowest maximum SLL compared with other algorithms. Moreover, the power pattern performances of different algorithms are tested by the electromagnetic simulations, and the results show that the proposed ICSO has the best optimization ability.
