Title
(EN) ANTENNA AND ELECTRONIC DEVICE INCLUDING THE SAME
(FR) ANTENNE ET DISPOSITIF ÉLECTRONIQUE LA COMPORTANT
Abstract
(EN)
In an embodiment, an electronic device may include a housing having an inner space, a first printed circuit board including a wireless communication circuit, an antenna structure connected to the wireless communication circuit through a first electrical path, and a tunable circuit having a first resistance value and disposed on a second electrical path. The electronic device may further include a low-resistance circuit disposed on a third electrical path branched from the second electrical path, and including a resistor and an inductor, the resistor having a second resistance value determined based on the first resistance value, and the inductor having a constant inductance value and disposed between the resistor and the ground. The electronic device may also include at least one processor configured to control the tunable circuit.

Dans un mode de réalisation, un dispositif électronique peut comprendre un boîtier doté d'un espace interne, une première carte de circuit imprimé dotée d'un circuit de communication sans fil, une structure d'antenne connectée au circuit de communication sans fil par l'intermédiaire d'un premier trajet électrique, et un circuit accordable présentant une première valeur de résistance et disposé sur un second trajet électrique. Le dispositif électronique peut en outre comprendre un circuit à faible résistance disposé sur un troisième trajet électrique ramifié à partir du second trajet électrique, et comprenant une résistance et un inducteur. La résistance présente une seconde valeur de résistance déterminée sur la base de la première valeur de résistance, et l'inducteur présente une valeur d'inductance constante et est disposé entre la résistance et le sol. Le dispositif électronique peut également comprendre au moins un processeur configuré pour commander le circuit accordable.
