Abstract

L'invention concerne une antenne conçue pour des bandes de fréquences multiples. L'antenne comprend au moins un groupe d'éléments rayonnants à large bande. Le groupe d'éléments rayonnants à large bande comprend au moins deux éléments rayonnants à large bande et des dispositifs répartiteurs de fréquences correspondant de manière biunivoque aux éléments rayonnants à large bande. Les dispositifs répartiteurs de fréquences peuvent fonctionner dans au moins deux bandes de sous-fréquences différentes. Etant donné que les dispositifs répartiteurs de fréquences peuvent fonctionner dans au moins deux bandes de sous-fréquences différentes, lorsque les éléments rayonnants à large bande sont connectés aux dispositifs répartiteurs de fréquences, les éléments rayonnants à large bande peuvent également fonctionner indépendamment dans les deux bandes de sous-fréquences ou plus, de telle sorte que l'antenne comprenant les dispositifs répartiteurs de fréquences et les éléments rayonnants à large bande peut fonctionner indépendamment dans des bandes de sous-fréquences différentes, élargissant ainsi l'adaptabilité de l'antenne.
