Antenna device and electronic device including the same

Abstract

Various embodiments of the present disclosure may provide an electronic device that includes: a first cover configured to form a first surface of the electronic device; a second cover configured to form a second surface of the electronic device, the second cover being opposite to the first surface; a conductive sidewall configured to surround at least a part of a space formed between the first cover and the second cover; a conductive member located in the space and configured to integrally extend from the conductive sidewall, the conductive member including a first surface directed toward the first cover and a second surface directed toward the second cover; a non-conductive member located in the space to make contact with the conductive member, the non-conductive member including a first surface directed toward the first cover and a second surface directed toward the second cover; a conductive pattern disposed on the second surface of the non-conductive member and electrically connected to the conductive member; and a conductive structure disposed between the conductive pattern and the conductive member to electrically connect the conductive pattern to the conductive member. The non-conductive member may include a via hole that at least partially passes through the area between the first surface and the second surface thereof, and the conductive structure may include a first part having a first cross-sectional area and a second part having a second cross-sectional area that is larger than the first cross-sectional area, wherein at least a part of the conductive structure may be disposed within a through-hole of the non-conductive member, and the second part may be disposed closer to the second surface of the non-conductive member than the first part. Various other embodiments are possible.
