Abstract

Un dispositif électronique peut comprendre un premier boîtier, un second boîtier pour loger un dispositif d'entrée, et un ensemble charnière pour relier le premier boîtier au second boîtier. En outre, le dispositif électronique peut comprendre une structure de support reliée de façon rotative au second boîtier sur une surface arrière qui est opposée au dispositif d'entrée. La structure de support peut être utilisé entre une position fermée et une position ouverte. En outre, le dispositif électronique peut comprendre une antenne disposée sur la structure de support. L'antenne peut se déplacer par rapport au second boîtier lorsque la structure de support se déplace entre la position fermée et la position ouverte.
