Simulación de arreglos de antenas distribuidas en un ángulo sólido de 4pi sr para la conformación de patrones de radiación cuasi isotrópicos

Abstract

This work shows a study carried out in different configurations of antenna arrays, based on simulations in CST Studio Suite, to obtain quasi-isotropic radiation patterns. Each array is individually constituted by radiating elements with omnidirectional radiation characteristics as well as those with directional radiation characteristics. After that briefly summarizes the main characteristics of a radiating element and establishes the state of the art which abstracts those works reported in the scientific literature and related to this subject. Next, the document details the methodology of the present study. It describes graphically the positioning algorithms which propose the location of the radiating elements. For each algorithm the respective pseudocoding is presented. Likewise, the radiant elements proposed for this work are specified along with their modeling and optimization in CST Studio Suite. Finally. Once the different array configurations have been established, it presents the results obtained from the simulations. In each simulation different feeding scenarios are considered based, initially, on a progressive phase change. Subsequently, the feeding scenario is optimized, based on the results previously obtained, to obtain those desired radiation patterns.
