(EN) ANTENNA DEVICE AND PORTABLE ELECTRONIC DEVICE COMPRISING SUCH AN ANTENNA DEVICE
(FR) DISPOSITIF D'ANTENNE ET DISPOSITIF ÉLECTRONIQUE PORTATIF COMPRENANT LEDIT DISPOSITIF D'ANTENNE
Abstract
(EN)
An antenna device (18) for a portable electronic device, preferably for the FM frequency range, comprises a radiator element (16) provided with a first antenna connection point (23), a matching element (26) connected between the radiator element (16) and ground, and an amplifier stage (24) connected to the first antenna connection point (23), where an output of the amplifier stage (24) is connectable to a radio circuit (22). The radiator element is at least a part of the cover of the portable radio communication device.
(FR)
La présente invention a trait à un dispositif d'antenne (18) destiné à un dispositif électronique portatif, de préférence pour la bande de fréquences FM, qui comprend un élément rayonnant (16) équipé d'un premier point de connexion d'antenne (23), un élément d'adaptation (26) connecté entre l'élément rayonnant (16) et la masse, et un étage amplificateur (24) connecté au premier point de connexion d'antenne (23), où une sortie de l'étage amplificateur (24) peut être connectée à un circuit radio (22). L'élément rayonnant constitue au moins une partie du couvercle du dispositif de radiocommunication portatif.
