Abstract

Sont divulgués dans la présente demande un dispositif de communication, un système de plateforme, un ensemble de connexion électrique et une unité de connexion. Le dispositif de communication est connecté en communication à une plateforme mobile, de telle sorte que la plateforme mobile accède à un réseau de communication. La plateforme mobile comprend une partie métallique. Le dispositif de communication comprend un corps de dispositif et une pièce de mise à la terre. Le corps de dispositif peut être connecté de manière amovible à la plateforme mobile, et comprend une antenne et une couche de mise à la terre correspondant à celle-ci. La pièce de mise à la masse est électriquement couplée à la couche de mise à la terre et à la pièce métallique de façon à augmenter la zone de mise à la terre de l'antenne. De cette manière, les performances de rayonnement du dispositif de communication sont améliorées, et la fiabilité d'accès au réseau de communication par la plateforme mobile est améliorée. De plus, la pièce métallique de la plateforme mobile est utilisée pour augmenter la zone de mise à la masse, de telle sorte que la conception de miniaturisation du dispositif de communication est facilitée.
