Abstract

Procédé de balayage électronique à partir du faisceau émis par une antenne plate consistant à provoquer le balayage dans le plan de la dispersivité en fréquence de l'antenne plate et à rattrapper la dispersivité due à l'antenne plate. Procédé consistant à combiner avec l'antenne plate un réseau de fils conducteurs particulier dont certains, commandés de façon telle, en fonction de la fréquence émise par l'antenne plate, que le déphasage qu'ils introduisent rattrappe la dispersivité de l'antenne plate. Structures de balayage électronique assurant le balayage dans deux directions orthogonales; structures cylindriques ou coniques assurant le balayage électronique selon le plan comportant l'axe de la structure.
