Abstract
Architecture d'antenne permettant l'émission et la réception en tribande et en quadribande de fréquences à la norme GSM dans une unité mobile avec un gain nécessaire sans augmentation de la consommation d'énergie. L'unité mobile utilise un circuit de commande (30) pour unifier une première antenne et une seconde antenne, dans lequel la première antenne peut fonctionner à une première fréquence et à une deuxième fréquence et la seconde antenne peut fonctionner à une troisième fréquence et à une quatrième fréquence. Le circuit de commande (30) inclut un circuit de décalage de phase (50) pour chaque antenne. Les circuits de décalage de phase interdisent à chaque antenne de charger l'autre antenne, ce qui élimine efficacement le VSWR (rapport d'ondes stationnaires de tension) excessif pour accroître le gain.
