Abstract
(EN) The present disclosure relates to a method for sensing whether an external object is close and an electronic device for supporting same. An electronic device according to an embodiment of the present disclosure may comprise: a wireless communication circuit; an antenna electrically connected to the wireless communication circuit and configured to be fed at a first point from the wireless communication circuit; a voltage sensing unit including a circuit that senses a peak voltage applied to the antenna; and a processor electrically connected to the voltage sensing unit and the wireless communication circuit, wherein the processor is configured to: on the basis of a peak voltage sensed by the voltage sensing unit, determine whether an external object is close to the electronic device within a designated distance; and on the basis of determination that the external object is close within the designated distance, control the magnitude of power applied to the antenna, through the wireless communication circuit.
(FR) La présente invention concerne un procédé destiné à détecter si un objet externe est proche et un dispositif électronique pour le prendre en charge. Un dispositif électronique selon un mode de réalisation de la présente invention peut comporter: un circuit de communication sans fil; une antenne reliée électriquement au circuit de communication sans fil et configuré pour être alimentée en un premier point à partir du circuit de communication sans fil; une unité de détection de tension comprenant un circuit qui détecte une tension de crête appliquée à l’antenne; et un processeur relié électriquement à l’unité de détection de tension et au circuit de communication sans fil, le processeur étant configuré pour: sur la base d’une tension de crête détectée par l’unité de détection de tension, déterminer si un objet externe est proche du dispositif électronique dans la limite d’une distance désignée; et sur la base d’une détermination selon laquelle l’objet externe est proche dans la limite de la distance désignée, commander l’amplitude d’une puissance appliquée à l’antenne, par l’intermédiaire du circuit de communication sans fil.
