Abstract
(EN)
The present invention relates to a method for matching an antenna of a portable terminal and to an apparatus for same, which are configured to set a predetermined match value for an antenna in response to a selected channel, and to change the match value when reception performance in a channel is degraded in a broadcast reception mode. The present invention supports an adaptive control which can optimize frequency matching characteristics in accordance with the change in the performance of the antenna using a control signal. Consequently, the present invention provides said portable terminal with an optimum receiving environment.

La présente invention concerne un procédé d'adaptation d'une antenne d'un terminal portable et un appareil associé, ceux-ci étant configurés en vue de spécifier une valeur prédéterminée d'adaptation d'une antenne en réponse à un canal choisi, et de modifier la valeur d'adaptation lorsque les performances en réception sur un canal sont dégradées dans un mode de réception de diffusion. La présente invention prend en charge une commande d'adaptation susceptible d'optimiser les caractéristiques d'adaptation en fréquence en fonction de la variation des performances de l'antenne à l'aide d'un signal de commande. Par conséquent, la présente invention fournit un environnement de réception optimal pour ledit terminal portable.
