Estudio de estructuras radiantes planares en un arreglo 4 × 4 para la obtención de reconfiguración en polarización circular para la banda X utilizando la herramienta de simulación Antenna Toolbox de MATLAB.

Abstract

This work proposes a 4 × 4 patch antenna array at an operation frequency of 10 GHz fed to obtain circular polarization. Chapter one there is a brief summary of the concepts related to the elliptical polarization of the electromagnetic wave, obtention of circular polarization in arrays where feeding types and characteristics are shown, antenna implementations reported in the literature that fit to the development of the present project. Furthermore, the operation and use of the MATLAB Antenna Toolbox tool is briefly reviewed.

Chapter two describes the methodology for the development of the simulation model in MATLAB considering, firstly, a properly size and coupling for the patch antenna to use it later as part of the planar array.

In chapter three, a results analysis is carried out by means of simulation of the structure of the planar array taking into consideration circuital parameters (coupling) and radiant parameters (radiation lobe, directivity, axial ratio, Co-polarization and X-polarization).

Chapter fourth presents the conclusions and recommendations of this work.
