Abstract

La présente demande concerne un ensemble de décoration de caméra et un dispositif électronique. L'ensemble de décoration de caméra comprend un corps d'élément décoratif. Le corps d'élément décoratif comprend une portion métallique, et au moins une partie de la portion métallique forme un premier élément rayonnant. L'ensemble de décoration de caméra est utilisé pour être installé sur un boîtier du dispositif électronique. Le premier élément rayonnant comprend un premier point d'alimentation et au moins un premier point de mise à la terre qui sont espacés l'un de l'autre ; le premier point d'alimentation est utilisé pour être connecté électriquement à une première extrémité d'alimentation du dispositif électronique ; le premier point de mise à la terre est utilisé pour être connecté électriquement à un plan de mise à la terre du dispositif électronique ; un appareil d'antenne du dispositif électronique est utilisé pour une communication dans une première bande de fréquences ; le premier élément rayonnant est utilisé pour prendre en charge la communication dans la première bande de fréquences ; et l'appareil d'antenne et le premier élément rayonnant sont connectés électriquement à une même puce radiofréquence. Selon la présente demande, la portion métallique du corps d'élément décoratif est utilisée en tant que premier élément rayonnant, et le premier élément rayonnant et l'appareil d'antenne sont connectés électriquement à une même puce radiofréquence, ce qui permet d'améliorer les performances d'antenne d'un dispositif électronique tout en libérant la pression de disposition d'antenne sur un cadran du dispositif électronique.
