dc.description.abstractIn this thesis, the characterization of the Small-Phased-Array-Fed Discrete Lens Array (SPAF-DLA) was developed, for the purpose of analyzing an alternative architecture to improve antenna array technology. SPAF-DLA is composed of a small phased array (as feeder) and a discrete lens array (as aperture lens). The purpose of the characterization is to determine the quality of the radiation pattern; the following parameters will be examined: the gain (G), the minimum side lobe level (SLL), the narrowest possible halfpower beamwidth (HPBW), the scanning range (SR), and the power distribution in the SPAF. In order to obtain an optimum power distribution, the phase and amplitude in the feeder (i.e. SPAF) was calculated for a given radiation pattern, through of an algorithm optimization. In additional, two synthesis methods were developed and analyzed for the characterization of the SPAF-DLA. As a result, the comparison of 1-D SPAF-DLA’s performance with respect to a PHA and a passive DLA (feeders on its focal arc) to compute the cost effectiveness of each structure, with respect to its construction and operating power.
dc.description.abstractEn esta tesis, se desarrolló la caracterización del Small-Phased-Array-Fed Discrete Lens Array (SPAF-DLA), con el fin de analizar una arquitectura alternativa para mejorar la tecnología de la matriz de antenas. SPAF-DLA se compone de una pequeña matriz en fase (como alimentador) y una matriz de lente discreta (como lente de apertura). El propósito de la caracterización es determinar la calidad del patrón de radiación; Se examinarán los siguientes parámetros: la ganancia (G), el nivel mínimo de los lóbulos laterales (SLL), la anchura de haz a 3 dB de potencia (HPBW) más estrecha posible, el rango de exploración (SR) y la distribución de potencia en el SPAF. Con el fin de obtener una distribución de potencia óptima, se calculó la fase y la amplitud en el alimentador (es decir, SPAF) para un patrón de radiación dado, a través de una optimización del algoritmo. Además, dos métodos de síntesis fueron desarrollados y analizados para la caracterización de SPAFDLA. Como resultado, la comparación del desempeño del SPAF-DLA 1-D con respecto al PHA y al DLA pasivo (alimentadores en su arco focal) para calcular la rentabilidad de cada estructura, con respecto a su potencia de construcción y operación.
