Title
(EN) METHOD AND APPARATUS FOR A TUNABLE ANTENNA
(FR) PROCÉDÉ ET APPAREIL POUR ANTENNE ACCORDABLE
Abstract
(EN) A method for tuning an antenna comprising determining an operating frequency band of the antenna, and adjusting a capacitance of a tunable load according to the operating frequency band, wherein the tunable load is electromagnetically coupled to the antenna via a parasitic arm, and wherein the operating frequency band depends on the capacitance.
(FR) L'invention concerne un procédé pour accorder une antenne, consistant à déterminer une bande de fréquence de fonctionnement d'antenne, et à régler une capacité de charge accordable en fonction de la bande de fréquence de fonctionnement, la charge accordable étant électro-magnétiquement couplée à l'antenne via un bras parasite et la bande de fréquence de fonctionnement dépendant de la capacité.
