Electronic device including antenna

Abstract

According to an embodiment of the disclosure, an electronic device may include: a front plate, a rear plate disposed opposite the front place, a side surface part surrounding at least a part of a space between a front plate and the rear plate, a support disposed in the space and laterally surrounded by the side surface part, communication circuitry configured to transmit and/or receive a signal having a selected or designated frequency band through a conductive unit comprising a conductive material having at least a part thereof included in the side surface part, a display disposed between the support and the front plate and visible through the front plate, a first circuit substrate electrically connected to the display, disposed between the display and the support, and that a display driving circuit is disposed thereon, a second circuit substrate electrically connected to the display, disposed between the display and the support, and that a touch controller IC is disposed thereon, a first conductive sheet having at least a part thereof disposed between the support and the first circuit substrate, and a second conductive sheet disposed in the support between the display and the support and including a first conductive area overlapping the first conductive sheet when viewed over the rear plate and a second conductive area extending from the first conductive area and overlapping the second circuit substrate.
