Abstract
SE PRESENTA UN METODO PARA ENFASAR ANTENAS DE RED DE ELEMENTOS ACTIVOS DE ORIENTACION DE RETICULA REGULARMENTE SEPARADA, SIN EL USO DE UNA BANDA DE CAMPO CERCANO O DE CAMPO LEJANO. EL METODO UTILIZA EL ACOPLAMIENTO MUTUO Y/O LAS REFLEXIONES PARA SUMINISTRAR UNA SEÑAL DESDE UN ELEMENTO (1, 3, 5) HASTA SUS ELEMENTOS CIRCUNDANTES (2, 4). ESTA SEÑAL SUMINISTRAR UNA REFERENCIA PARA PERMITIR QUE LOS ELEMENTOS (1, 2, 3, 4, 5) ESTEN EN FASE UNOS CON RESPECTO A LOS OTROS. DESPUES DE LA PRIMERA ETAPA EL METODO SE COMPLETA, LA RED DE ELEMENTOS ACTIVO SE PONE EN FASE, EN AL MENOS, CUATRO RETICULAS INTERCALADAS (1-3-5.../24...). ESTAS RETICULAS INTERCALADAS (1-3-5.../2-4...) ESTAN EN FASE UNAS CON RESPECTO A LAS OTRAS, COMPLETANDO DE ESTA FASE EL PROCESO DE ENFASAMIENTO.
