Abstract

GUIA DE ONDAS DE ALIMENTACION (15) PARA UNA ANTENA (10) DE RED Y ANTENA CORRESPONDIENTE. LA ANTENA REDUCE LOS ERRORES DE FASE EN LA UNION DEL ACOPLAMIENTO. LA GUIA DE ONDAS DE ALIMENTACION PERFECCIONADA (15) DE LA PRESENTE INVENCION INCLUYE UNA PRIMERA Y SEGUNDA PAREDES PARALELAS RANURADAS (35 Y 36), A LO LARGO DE LA LONGITUD DE AQUELLA. LA PRIMERA PARED (35) INCLUYE, A TRAVES DE ELLA, UNA PRIMERA RANURA ALARGADA (27) QUE TIENE UN PRIMER EJE LONGITUDINAL (44). LA SEGUNDA PARED (37) INCLUYE UNA SEGUNDA RANURA ALARGADA (32), QUE ESTA SITUADA SOBRE LA SEGUNDA PARED (37) Y OPUESTA A LA PRIMERA RANURA (27) SOBRE LA PRIMERA PARED (35). LA SEGUNDA RANURA (32) TIENE UN EJE LONGITUDINAL (42) QUE ES ORTOGONAL CON EL EJE LONGITUDINAL (44) DE LA PRIMERA RANURA (27). APLICACION EN SISTEMAS DE RADAR.
