Abstract
According to various embodiments, an electronic device may include: a housing including a front plate and a rear plate disposed opposite the front plate; a display disposed in a space between the front plate and the rear plate and viewable through at least a portion of the front plate; an antenna structure including at least one coil having a first surface facing the rear plate in the space and a second surface facing a direction opposite the first surface, the antenna structure configured to transmit and/or receive a signal of a selected or designated frequency; a first magnetic sheet disposed at the first surface; a second magnetic sheet at least partially overlapping the first magnetic sheet when viewed from above the rear plate, the second magnetic sheet being disposed at the second surface; and a third magnetic sheet disposed closer to the rear plate than the second surface, and spaced apart from the first magnetic sheet to have electromagnetically designated isolation with the first magnetic sheet with the second magnetic sheet interposed therebetween, when viewed from above the rear plate.
