Abstract
(EN)
A tuneable antenna suitable for mobile telecommunications or small terminal applications comprises an electrically conductive antenna element (6) and a tuning element (8) proximate to the antenna element, wherein the tuning element is movable or switchable between at least two positions relative to the antenna element to tune the tuneable antenna to corresponding different resonant frequencies.
(FR)
L'invention concerne une antenne réglable convenant pour les télécommunications mobiles ou pour les applications se rapportant aux terminaux de petite dimension. Cette antenne comprend un élément rayonnant (6) conducteur d'électricité, et un élément (8) de réglage placé à proximité de l'élément rayonnant. L'élément de réglage peut être déplacé ou commuté entre au moins deux positions relativement à l'élément rayonnant, afin de permettre le réglage de l'antenne sur différentes fréquences résonantes correspondantes.
