CONTRERAS, Andry  e  TELLO-MAITA, Josimar. Modification of the particle swarm optimization method through the intervention technique and its application for antenna design. Dyna rev.fac.nac.minas [online]. 2021, vol.88, n.218, pp.110-118.  Epub 23-Mar-2022. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v88n218.93260.

In this research, a modification of the particle swarm optimization method was proposed, which is based on an intervention technique for the design of antennas. The proposed method was tested through its application on typical benchmark functions. Moreover, it was applied to the optimal design of a narrow band antenna and two ultra-wideband antennas through shape and hybrid optimization. The objective function was based on minimizing the S 11 magnitude in the desired frequency range to improve impedance matching. The modified method had a better performance than the original particle swarm optimization in the typical benchmark functions, and the best results were obtained for the antenna optimization process. Therefore, this method is a good alternative to be applied in these processes because it allows obtaining a better quality of solution and reducing the number of evaluations of the objective function.
