METHOD AND SYSTEM FOR OPTIMIZING LENS IN VIVALDI ANTENNA, AND RELATED DEVICE

WIPO Patent Application WO/2024/078157

A1

The present invention belongs to the field of antennas, and particularly relates to a method and system for optimizing a lens in a Vivaldi antenna, and a related device. The method comprises: constructing an initial population for a genetic algorithm by using structure parameters of a lens as optimization parameters; performing lens modeling in a simulation environment according to individuals in the initial population, so as to obtain simulation modeling data; computing the individual fitness of each individual according to the simulation modeling data; performing genetic computation on the individuals in the initial population according to a preset individual selection rule, so as to obtain a genetic individual; and determining whether the genetic algorithm meets a preset termination condition, and if the genetic algorithm does not meet the preset termination condition, updating and iterating the initial population with the genetic individual, and optimizing same by using the genetic algorithm; and if the genetic algorithm meets the preset termination condition, outputting an optimal individual according to the genetic individual, and outputting, as a final parameter of the lens, the structure parameter corresponding to the optimal individual. In the present invention, a genetic algorithm is used to optimize parameters of a dielectric lens, such that the gain of an antenna loaded with the lens is significantly improved in the entire operating frequency band.
