Abstract

Une antenne et un dispositif de communication mobile sans fil intégrant l'antenne sont proposés. L'antenne comprend une première section de conducteur, couplée électriquement à un premier point d'alimentation, une deuxième section de conducteur, couplée électriquement à un deuxième point d'alimentation, et une structure de commande de rayonnement en champ proche pouvant commander des caractéristiques de rayonnement en champ proche généré par l'antenne. Les structures de commande de rayonnement en champ proche comprennent un élément parasite positionné à côté de la première section de conducteur et configuré pour commander des caractéristiques de rayonnement en champ proche généré par la première section de conducteur, et un diffuseur dans la deuxième section de conducteur configuré pour diffuser le rayonnement en champ proche généré par la deuxième section de conducteur dans une pluralité de directions.
