Abstract

EN UNA ESTACION DE RADIO PARA SISTEMAS DE COMUNICACION MOVIL, SE SUPERVISAN LAS RAMAS DE RECEPCION DE AL MENOS DOS UNIDADES DE ANTENA DE DISTINTA POLARIZACION PARA OBTENER UNA EXPRESION DEL SENTIDO DE POLARIZACION DE LA ONDA INCIDENTE. EN CORRESPONDENCIA CON EL SENTIDO DE POLARIZACION DE LA ONDA INCIDENTE, TIENE LUGAR UNA ESTRUCTURACION ADAPTATIVA DE LA CARACTERISTICA DE RADIACION, QUE ESTRUCTURA EL SENTIDO DE POLARIZACION DE LA ONDA IRRADIADA PARA IGUALAR EL ENLACE DE COMUNICACION EN FUNCION DE LA PONDERACION DE LAS SEÑALES RECIBIDAS POR LAS RAMAS DE RECEPCION. POR EJEMPLO, MEDIANTE UNA ESTACION DE RADIO COMO LA DE LA INVENCION, PUEDE MEJORARSE EL ENLACE DESDE UNA ESTACION BASE A UNA ESTACION MOVIL EN UN SISTEMA DE COMUNICACIONES MOVILES.
