Abstract

UNA ANTENA DE RADIO FRECUENCIA CUADRIFILAR PENSADA PRIMERAMENTE PARA RECIBIR SEÑALES DESDE UN SATELITE EN ORBITA ALREDEDOR DE LA TIERRA, QUE PARA LA NAVEGACION TIENE CUATRO ELEMENTOS DE CABLE HELICOIDALES (10A-10D) CON UNA FORMA Y MONTADOS DE TAL MANERA QUE DEFINEN UNA ENVOLTURA CILINDRICA (12). LOS ELEMENTOS (10A-10D) SON COEXTENSIBLES EN LA DIRECCION AXIAL DE LA ENVOLTURA Y ESTAN MONTADOS EN SUS EXTREMOS OPUESTOS EN DOS PANELES DE CIRCUITO IMPRESO (16, 17) DESCANSANDO EN PLANOS SEPARADOS PERPENDICULARES AL EJE (14) ESTANDO LOS EXTREMOS DE LOS ELEMENTOS SOLDADOS A LOS CAMINOS DE LOS CONDUCTORES EN LOS PANELES (16, 17), CONSTITUYENDO LOS CAMINOS UNOS ELEMENTOS DE IMPENDANCIA ENTRE LOS ELEMENTOS HELICOIDALES (10A-10D) Y UN ALIMENTADOR COAXIAL LOCALIZADO AXIALMENTE (18). LOS CAMINOS DE LOS CONDUCTORES SON TALES QUE LA LONGITUD EFECTIVA DE UN PAR (10A, 10B) DE ELEMENTOS HELICOIDALES Y ELEMENTOS DE IMPENDANCIA ASOCIADOS ES MAYOR QUE LA DEL OTRO PAR (10C, 10D) Y ELEMENTOS DE IMPENDANCIA ASOCIADOS. DE ESTA MANERA, LA CUADRATURA DE FASE ENTRE LOS DOS PARES SE OBTIENE EN LA FRECUENCIA DE OPERACION SIN UTILIZAR ELEMENTOS HELICOIDALES DE DISTINTAS FORMAS, Y CON POCO O NINGUN AJUSTE DE LOS ELEMENTOS EN EL PROCESO DE FABRICACION.
