Abstract

L'invention concerne un dispositif d'antenne pour téléphone mobile à alimentation par couplage. Le dispositif d'antenne comprend une carte principale disposée dans un téléphone mobile, une partie décorative métallique « boucle » montée sur l'avant du téléphone mobile, un support d'antenne monté sur un boîtier du téléphone mobile, et un premier rayonneur d'antenne et un second rayonneur d'antenne disposés sur le support d'antenne. Le second rayonneur d'antenne comprend un jour. Une source d'alimentation radiofréquence est disposée sur la carte principale, et la source d'alimentation radiofréquence est connectée au second rayonneur d'antenne via un connecteur d'antenne. La carte principale est connectée au premier rayonneur d'antenne et à la partie décoratrice métallique via le connecteur d'antenne. La partie décoratrice métallique est en communication avec le second rayonneur d'antenne via le connecteur d'antenne. La présente invention adopte savamment la partie décoratrice métallique sur l'avant du téléphone mobile en tant que partie de l'antenne, et améliore grandement la texture métallique de toute la machine par rapport à la forme. La présente invention adopte une démarche d'alimentation par couplage afin de résoudre correctement le problème d'une antenne sensible du fait que les performances de l'antenne se dégradent fortement lorsqu'un jour d'un cadre métallique est couvert par la main.
