Diseño y optimización de un array de antenas microstrip patch con polarización circular para 2.45Ghz

Abstract

[EN] The main purpose of this project is the improvement of an antenna already manufactured. This radiant system works for applications in the 2.45GHz frequency range and broadcasts with a circular polarization. The antenna is analyzed to see if the impedance and the axial ratio are accurate or need to be adapted since these two parameters are the most important in the system performance. Concurrently, new models will be simulated and tested with the same purpose. The new prototype will be made with the software FEKO and ADS. These models preserve the initial design, which is an array of four elements. On the other hand, a brief introduction to the theoretical concepts is necessary in order to know the most important parameters of the antennas where the principal focus is the microstrip technology. Lastly, the real measurement will be proved and verified.[ES] Se va a realizar un array basado en la tecnología microstrip, cuyo objetivo principal del diseño es que a la frecuencia 2.45Ghz la antena tenga una ganacia superior a 8dB y polarización circular. Este diseño esta basado en un modelo ya hecho en donde hay errores que se pretenden correguir. También hay una explicación teórica sobre los conceptos básicos y los parámetros de la antenas, donde el foco principal es la tecnología microstrip.
