Abstract

L'INVENTION CONCERNE UNE ANTENNE D'EMISSION D'ENERGIE A HAUTE FREQUENCE DESTINEE A BALAYER L'ESPACE AVEC UN FAISCEAU COLLIMATE, DANS UN ANGLE RELATIVEMENT LARGE. L'ANTENNE COMPORTE DES ELEMENTS DISPOSES LE LONG D'UN LIEU INCURVE, PRODUISANT UN FAISCEAU DIRIGE ET NON COLLIMATE, ET UNE LENTILLE A HAUTE FREQUENCE DISPOSEE ENTRE LES ELEMENTS D'ANTENNE ET L'ESPACE POUR COLLIMATER L'ENERGIE A HAUTE FREQUENCE EN PRODUISANT UN FAISCEAU COLLIMATE QUI BALAYE L'ESPACE. LA DISPOSITION DES ELEMENTS D'ANTENNE LE LONG DU LIEU INCURVE PRODUIT UNE DISTRIBUTION D'AMPLITUDE PRATIQUEMENT UNIFORME DANS TOUT LE FAISCEAU. L'INVENTION S'APPLIQUE NOTAMMENT A DES ANTENNES DE RADAR.THE INVENTION RELATES TO A HIGH FREQUENCY ENERGY EMISSION ANTENNA FOR SCANING SPACE WITH A COLLIMATE BEAM, AT A RELATIVELY WIDE ANGLE. THE ANTENNA FEATURES ELEMENTS ARRANGED ALONG A CURVED PLACE, PRODUCING A DIRECTED AND NON-COLLIMATE BEAM, AND A HIGH FREQUENCY LENS ARRANGED BETWEEN THE ANTENNA ELEMENTS AND THE SPACE TO COLLIMATE HIGH FREQUENCY ENERGY BY PRODUCING A COLLIMATE BEAM THAT SWEANS THE SPACE. THE ARRANGEMENT OF THE ANTENNA ELEMENTS ALONG THE CURVED PLACE PRODUCES A PRACTICALLY UNIFORM AMPLITUDE DISTRIBUTION THROUGHOUT THE BEAM. THE INVENTION APPLIES IN PARTICULAR TO RADAR ANTENNAS.
