Abstract

SISTEMA DE ANTENAS INTEGRADAS PARA APARATOS DE RADAR. COMPRENDE UNA PRIMERA ANTENA, EN LA QUE UN EXCITADOR ES POSICIONADO A LA DISTANCIA FOCAL DE UN REFLECTOR DE DOBLE CURVATURA CON DIMENSIONES DIFERENTES DE ALTURA Y ANCHURA, A FIN DE GENERAR UN PRIMER DIAGRAMA DE RADIACCION DIRECTIVA Y DE UNA SEGUNDA ANTENA, COMPUESTA POR EL REFLECTOR DE LA PRIMERA ANTENA Y DE VARIAS SUPERFICIES DE MICRO-STRIP ADAPTADAS A LA DOBLE CURVATURA DEL REFLECTOR Y FIJADAS SOBRE EL MISMO. LA SUPERFICIE RADIANTE DEL MICRO-STRIP SE HALLA POSICIONADA SOBRE EL REFLECTOR A UNA DISTANCIA *FORMULA*, DONDE LAMBDA = LONGITUD DE ONDA DE LA FRECUENCIA DEL EXCITADOR Y K PUEDE SER = 0, 1, 2, 3, ...
