Diseño y simulación de una antena yagi uda mediante el uso de algoritmos genéticos para el laboratorio de antenas de la Universidad Politécnica Salesiana

Abstract

In the writing optimization by the method of genetic algorithms, design and simulation of a Yagi Uda, for which it was investigated first on the antennas, their physical characteristics and parameters of radiation occurs, it was also investigated on antenna Yagi Uda, its geometry, its design parameters, its uses and applications, its importance in the telecommunications area, the elements that form, their function within the geometry of the antenna and the traditional design method based on frequency where working wavelength and the dimensions of the antenna elements according to this is obtained, then the corresponding simulation is performed to obtain the parameters that characterize radiation. Once the antenna is designed using the traditional method proceeded to search for information on Genetic Algorithms and their application to the design and optimization of antennas was analyzed as genetic algorithms can improve certain parameters of radiation by changing the lengths and distances of the elements part of the geometry of a Yagi Uda, is determined, the antenna design in software by setting the genetic operators selection, crossover and mutation to thereby obtain the best global solution finally were simulated antenna designed by genetic algorithms for radiation parameters. With the results of simulation corresponding to each design comparative analysis of the antenna designed by genetic algorithms with respect to the antenna designed by the traditional method where the optimization results obtained as parameters gain and directivity and a decrease is performed on the back facing relationship.
