Abstract

La présente invention se rapporte à une antenne interne conçue pour un combiné ainsi qu'à un procédé de conception de ladite antenne. La présente invention concerne une antenne interne pour combiné et un procédé de conception associé qui se caractérise en ce qu'un élément L/C est attaché à une ligne à fente d'une antenne interne, en ce que cet élément L/C attaché se déplace le long de la ligne à fente, ou en ce que ledit élément L/C ayant une inductance/capacité prédéterminée est attaché et détaché, ceci permettant une adaptation aisée à une fréquence de résonance.
