Abstract
Une antenne comprend une ouverture définissant une zone dalimentation de lantenne, louverture étant divisée en une pluralité de sous-réseaux discrets, et un réseau dalimentation ayant un port dentrée, une pluralité de ports de sortie, et une pluralité de conducteurs, chaque conducteur étant connecté entre le port dentrée et un port de sortie respectif de la pluralité de ports de sortie, et chaque port de sortie de la pluralité de ports de sortie étant connecté à un sous-réseau respectif de la pluralité de sous-réseaux. Une longueur de ligne dun conducteur de la pluralité de conducteurs est différente dune longueur de ligne dun autre conducteur de la pluralité de conducteurs pour introduire différents retards dans le temps entre le port dentrée et les ports de sortie respectifs.
