Abstract

L'invention concerne des modes de réalisation mettant en oeuvre un dispositif d'antenne, un système de station de base, et un procédé pour syntoniser le dispositif d'antenne. Le dispositif d'antenne comprend: une première antenne; une seconde antenne partageant un blindage avec la première antenne et présentant un sens de polarisation différent; un appareil de commande pour recevoir un signal de commande de syntonisation électrique pour la première antenne et/ou un signal de commande de syntonisation électrique pour la seconde antenne et, en fonction du signal de commande de syntonisation pour la première antenne, régler un angle d'inclinaison vers le bas de la première antenne et/ou, en fonction du signal de commande de syntonisation pour la seconde antenne, régler un angle d'inclinaison vers le bas de la deuxième antenne. A la différence de l'antenne double polarisation classique, dans laquelle un angle d'inclinaison vers le bas doit être partagée, les modes de réalisation de l'invention permettent de régler l'angle d'inclinaison vers le bas de deux groupes d'éléments d'antenne respectifs constituant une antenne double polarisation à blindage partagé, qui peuvent ainsi prendre en charge des bandes de fréquence différentes ou des systèmes différents dans une bande de fréquence pour adopter différents angles d'inclinaison vers le bas. Une seule antenne double polarisation suffit, sans câble d'alimentation d'antenne supplémentaire, ce qui réduit le coût du dispositif.
