Electronic device having side key comprising antenna

Abstract

Provided is an electronic device including a conductive housing including a first face facing a first direction, a second face facing a second direction opposite to the first direction, and a lateral face surrounding at least part of a space constructed between the first face and the second face, a printed circuit board seated inside the housing, and a side key fastened to an edge region of the housing, wherein the side key include a button portion of which one face covers a first through-hole constructed on the lateral face and the other face is exposed to the outside, an actuation portion extending from the face of the button portion covering the first through-hole towards the inside of the housing in such a manner that at least part of the extending portion is inserted to the first through-hole and at least part of the inserted portion moves in a third direction parallel to a normal direction of the lateral face of the housing according to whether the button portion is pressed, a side key circuit board including an outer contact portion pressed by a movement of the actuation portion and an inner contact portion which is in contact with the outer contact portion according to whether the outer contact portion is pressed, and including a switch module which produces an electric signal due to the contact of the outer contact portion and the inner contact portion, a side key bracket on which at least part of the side key circuit board is seated and which fixes and supports the side key circuit board, and an antenna which uses the first through-hole as an antenna aperture for transmitting/receiving radio waves. In addition thereto, various embodiments understood through this document are possible.
