Abstract

Selon l'invention, un organe d'antenne (8) est fixé à une carte d'antenne (7) de telle manière qu'un ressort d'alimentation d'antenne (11) connectant électriquement un élément d'antenne (8a) à la carte d'antenne (7) soit en appui sur l'élément d'antenne (8a). Dans cette situation, la carte d'antenne (7) est insérée dans une partie gorge (3b) formée le long du bord périphérique d'un boîtier (3). De cette manière, même pour un boîtier comportant une gorge au niveau d'une partie face latérale, un élément d'antenne peut être placé au voisinage de la partie périphérique la plus à l'extérieur du boîtier, ce qui permet d'améliorer les performances.
