Abstract

SE DESCRIBE UNA DISPOSICION DE ELEMENTOS MULTIPLES DESFASADOS EXPLORADA ELECTRICAMENTE, CON LOBULOS LATERALES REDUCIDOS Y DISTRIBUCION DECRECIENTE DEL CAMPO DE ABERTURA. LA DISPOSICION ES ALIMENTADA POR UNA RED (55) DE ALIMENTACION COLECTIVA UNIFORME, O INCLUYE UNA ABERTURA DE DISPOSICION PRINCIPAL CONSTITUIDA POR ELEMENTOS RADIANTES PRINCIPALES (72-75) Y PRIMERA Y SEGUNDA DISPOSICIONES AUXILIARES, CONSTITUIDAS POR ELEMENTOS RADIANTES AUXILIARES (70-71 Y 76-77). PARA UNA ABERTURA LINEAL, LAS SALIDAS PROCEDENTES DE LA RED DE ALIMENTACION (55) ESTAN DESFASADAS PARA DIRIGIR EL HAZ A UNO DE LOS LUGARES DISPONIBLES DEL HAZ, Y ESTAN ACOPLADAS A CORRESPONDIENTES ELEMENTOS DE LOS ELEMENTOS RADIANTES DE LA DISPOSICION PRINCIPAL (72-75) Y DE LOS ELEMENTOS RADIANTES DE LA DISPOSICION AUXILIAR (70-71 O 76-77). LOS DESFASES DIRECTORES DE HAZ PROVOCAN GRADIENTES UNIFORMES DE FASE ENTRE LOS ELEMENTOS DE LA DISPOSICION RESPECTIVA, Y ESTAN PREVISTOS CORRECTORES DE FASE BIESTATICOS (85-88) PARA CORREGIR LASDISCONTINUIDADES EN EL GRADIENTE DE FASE A TRAVES DE LAS ABERTURAS DE LAS DISPOSICIONES PRINCIPAL Y AUXILIAR. LA DISPOSICION SE PUEDE CONSTRUIR CON MODULOS IDENTICOS, DANDO COMO RESULTADO UN COMPARTIMIENTO MEJORADO A UN COSTE INFERIOR.
