Abstract

EL SISTEMA DE ANTENA DE ACUERDO CON LA INVENCION INCLUYE UNA LENTE (11), QUE ENFOCA LAS ONDAS ENTRANTES (10) EN PUNTOS FOCALES RESPECTIVOS (12A-C). UNOS DISPOSITIVOS HELICOIDALES DE SUMINISTRO (23A-C), QUE ESTAN DISPUESTOS CERCA DE DICHOS PUNTOS FOCALES (12A-C) Y PREFERIBLEMENTE INTEGRADOS EN DICHA LENTE (11), RECIBEN LAS ONDAS (10) Y LAS SEÑALES APROPIADAS SON ENVIADAS MEDIANTE LINEAS DE SUMINISTRO (14A-C) A UN RECEPTOR ADECUADO (15). MEDIANTE EL SISTEMA DE ANTENA DE ACUERDO CON LA INVENCION PUEDE SUMINISTRARSE UN SOPORTE MECANICO PARA LOS DISPOSITIVOS DE SUMINISTRO Y LAS LINEAS DE SUMINISTRO. SI SE USA UNA LENTE HEMISFERICA, EL SISTEMA DE ANTENA ES MENOS PESADO Y ESPECIALMENTE EN ESTE CASO LA LONGITUD DE LAS LINEAS DE SUMINISTRO REQUERIDAS PUEDEN REDUCIRSE E INCREMENTARSE LA EFICIENCIA DE RECEPCION. EL SISTEMA DE ACUERDO CON LA INVENCION SE USA PREFERIBLEMENTE COMO PARTE DE UN SISTEMA PARA RECIBIR MICROONDAS DE SATELITES DE EMISION DIRECTA DESDE DIFERENTES SATELITES.THE ANTENNA SYSTEM ACCORDING TO THE INVENTION INCLUDES A LENS (11), WHICH FOCUSES INPUT WAVES (10) ON RESPECTIVE FOCAL POINTS (12A-C). SOME HELICOIDAL SUPPLY DEVICES (23A-C), WHICH ARE DISPOSED NEAR SUCH FOCAL POINTS (12A-C) AND PREFERABLY INTEGRATED IN SUCH LENS (11), RECEIVE THE WAVES (10) AND THE PROPER SIGNALS ARE SENT BY MEDIUM (14A-C) TO A SUITABLE RECEIVER (15). THROUGH THE ANTENNA SYSTEM IN ACCORDANCE WITH THE INVENTION, A MECHANICAL SUPPORT MAY BE PROVIDED FOR THE SUPPLY DEVICES AND THE SUPPLY LINES. IF A HEMISPHERIC LENS IS USED, THE ANTENNA SYSTEM IS LESS HEAVY AND ESPECIALLY IN THIS CASE THE LENGTH OF THE SUPPLY LINES REQUIRED MAY BE REDUCED AND THE EFFICIENCY OF RECEPTION INCREASED. THE SYSTEM IN ACCORDANCE WITH THE INVENTION IS PREFERABLY USED AS PART OF A SYSTEM FOR RECEIVING DIRECT EMISSION SATELLITE MICROWAVES FROM DIFFERENT SATELLITES.
