Abstract
Various embodiments of the present invention relate to an electronic device including an antenna impedance matching circuit. The electronic device may comprise: at least one interface; at least one detection circuit for detecting a connection of at least one external device to the at least one interface; at least two matching circuits; an antenna; and a switch module for receiving, from the at least one detection circuit, at least one signal corresponding to whether the at least one external device is connected to the at least one interface, and for connecting the antenna to a matching circuit, among the at least two matching circuits, corresponding to the at least one signal. Various other embodiments are also possible.
