CHEN Gang, HUO Da, HE Zhiqiu, et al. Cross antenna array optimization method based on immune PSO algorithm[J]. 2021, (7): 28-31. DOI: 10.13873/J.1000-9787(2021)07-0028-04.
An optimization method of planar cross antenna array with low maximum side lobe level(MSLL)
narrow half power beam width(HPBW)and less array elements is proposed. In this method
the mathematical expression of cross array is discussed.Particle swarm optimization(PSO)algorithm is used to optimize the array
immune algorithm is used to improve the individual diversity of the population
so as to achieve better optimization results. this paper introduce a simple and quickly approach to obtain narrow HPBW planar antenna array with few elements and low MSLL.
