A study on directional pattern control of array antenna using optimization algorithm

Abstract (in Japanese) (See Japanese page) 
(in English) Next-generation mobile communication systems (Beyond 5G / 6G) are expected to realize ultra-high speed, ultra-low latency, and ultra-multiple connectivity. To realize these features, simultaneous formation of multiple beams and high-speed tracking are required. Simultaneous formation of multiple beams can be achieved by controlling the directional pattern of array antennas, and directional pattern control using optimization algorithms has been studied. However, global optimization algorithms, such as particle swarm optimization, have not been sufficiently investigated as optimization algorithms for directional pattern control. In this report, we examine directionality control algorithms based on global optimization algorithms, and evaluate the performance of various optimization algorithms using indices such as directionality gain, sidelobe level, and computation time.
