Abstract

EL OBJETIVO DEL PRESENTE INVENTO ES LA RECEPCION SIMULTANEA DE SEÑALES CON DIFERENTES POLARIZACIONES CON AYUDA DE ALIMENTADORES HELICOIDALES SIN OLVIDAR LOS SISTEMAS CONOCIDOS. DE ACUERDO CON ESTE INVENTO DOS O MAS ALIMENTADORES HELICOIDALES SON PROPORCIONADOS PARA CADA DIRECCION DE POLARIZACION. EL INVENTO PUEDE SER USADO POR EJEMPLO, PARA UN SISTEMA DBS.THE AIM OF THE PRESENT INVENTION IS THE SIMULTANEOUS RECEPTION OF SIGNALS WITH DIFFERENT POLARIZATIONS WITH THE HELP OF HELICAL FEEDERS WITHOUT FORGETTING KNOWN SYSTEMS. ACCORDING TO THIS INVENTION TWO OR MORE HELICAL FEEDERS ARE PROVIDED FOR EACH DIRECTION OF POLARIZATION. THE INVENTION MAY BE USED FOR EXAMPLE, FOR A DBS SYSTEM.
