COMPARACIÓN DE CORRELACIÓN DE ARREGLOS DE ANTENAS DE MICROCINTA CON DIFERENTES SUSTRATOS (CORRELATION ASSESSMENT OF MICROSTRIP ANTENNA ARRAYS WITH DIFFERENT SUBSTRATES)
Resumen
Los arreglos de antenas se han convertido en una pieza central de la mayoría de los sistemas de comunicación, sin embargo, su diseño y la evaluación sigue siendo un desafío. Un parámetro clave es la matriz de correlación, que relaciona los patrones de la antena y la propagación multitrayectoria. El propósito de este trabajo es hacer una comparación entre arreglos de antenas con diferentes sustratos tomando como base la correlación entre antenas. Para cumplir con el objetivo se simularon prototipos de arreglos de antenas con la misma geometría y diferentes sustratos. En cada uno de estos arreglos se utilizaron la misma cantidad de antenas; cuatro antenas. Todas estas simulaciones se realizarán en la frecuencia de 3500 MHz, la cual será una de las frecuencias principalmente utilizadas para la 5ª Generación de telefonía celular debajo de 6 GHz.
Palabras Clave: parche, microcinta, arreglos de antena, Parámetros S, directividad.
Abstract
Antenna arrays have become a centerpiece of most communication systems, yet their design and evaluation remain a challenge. A key parameter is the correlation matrix, which relates antenna patterns and multipath propagation. The purpose of this work is to make a comparison between antenna arrays with different substrates based on the correlation between antennas. To meet the objective, prototypes of antenna arrays with the same geometry and different substrates were simulated. In each of these arrays the same number of antennas were used; 4 antennas. All these simulations will be carried out on the 3500 MHz frequency, which will be one of the frequencies mainly used for the 5G cell phone generation below 6 GHz.
Keywords: patch, microstrip, antenna arrays, S-parameters, directivity.
