Abstract

La présente invention concerne un réseau d'antennes à ondes millimétriques et un terminal mobile. Le réseau d'antennes à ondes millimétriques comprend : une première antenne à plaque, une seconde antenne à plaque et une première structure d'isolation. La première antenne à plaque et la seconde antenne à plaque sont adjacentes l'une à l'autre et sont espacées l'une de l'autre. Un premier espace est formé entre la première antenne à plaque et la seconde antenne à plaque. La largeur du premier espace est inférieure à la moitié de la longueur d'onde d'un guide d'onde. La première structure d'isolation est partiellement ou complètement disposée dans le premier espace. La première structure d'isolation est utilisée pour augmenter le degré d'isolation entre la première antenne à plaque et la seconde antenne à plaque.
