Abstract (es_ES)

Este artículo describe la síntesis de diagramas de radiación con agrupaciones circulares de antenas utilizando elementos directivos, aplicables en los sistemas de antenas inteligentes (Smart Antennas) para la estación base, como una solución viable en sistemas UMTS y frente a las nuevas exigencias del mercado. Como elemento básico de diagrama de radiación directivo, se utilizarán hilos infinitos con corriente constante, frente a un cilindro metálico infinito, cuyos resultados serán fácilmente extensibles al caso de dipolos finitos frente a un cilindro (figura 3). La técnica utilizada será la de Fourier, como continuación de artículo Suárez -Ferrando [1] y se plantea un método para sintetizar diagramas de radiación utilizando una agrupación de N antenas tipo hilo infinito con corriente constante uniformemente distribuidas sobre un circulo y frente a un cilindro metálico infinito. Las corrientes que permiten la síntesis del diagrama deseado se podrán determinar con una expresión que se deducirá en el artículo.

Abstract (en_US)

This article describes the synthesis of radiation patterns with circular antenna arrays using directive elements, applicable in the intelligent antennas systems (Smart Antennas) for the base station, like a viable solution in UMTS systems and in front of the new demands of the market. As a basic element of directive radiation pattern, the infinite filament of constant current will be used, in front of a metallic infinite cylinder whose results will be easily expandable to the case of finite dipoles in front of infinite metallic cylinder. The used technique will be that of Fourier, as article continuation Suárez - Ferrando [1] and a method for synthesizing the radiation pattern with antenna array of N infinite filament of constant current uniformly disposed around a circular ring an in front of a cylinder is proposed. The required excitation currents are determined from a deduced formula in the paper.
