Abstract

L'invention concerne un dispositif de communications mobiles ayant une enceinte (15), qui comprend un système d'antenne et un système de traitement des signaux couplé au système d'antenne. Le système d'antenne comprend au moins deux antennes (1, 2) qui présentent chacune un diagramme de rayonnement différent. L'avantage considérable de l'invention est que ce dispositif peut automatiquement choisir l'antenne (1, 2) dont le diagramme de rayonnement est approprié à un environnement spécifique.
