Abstract

La présente invention concerne un dispositif électronique comprenant des antennes. Selon la présente invention, lorsque la taille visuellement apparente d'un écran change en fonction du mouvement d'un boîtier du dispositif électronique, des zones de masse pour les antennes du dispositif électronique sont séparées selon une structure de séparation de masses, et des masses disposées dans les zones de masse séparées par la structure de séparation de masses peuvent être sélectivement connectées au moyen d'éléments variables sélectionnés en fonction des bandes de fréquences utilisées par les antennes du dispositif électronique. Divers autres modes de réalisation sont possibles.
