ELECTRONIC DEVICE INCLUDING ANTENNA SUPPORT STRUCTURE

An electronic device includes a housing, an antenna structure disposed in an inner space of the housing, a wireless communication circuit disposed in the inner space, and a first bracket. The antenna structure includes a substrate having a first substrate surface facing in a first direction and a second substrate surface facing in a second direction opposite to the first substrate surface, and a plurality of chip antennas sequentially arranged on the first substrate surface in a third direction perpendicular to the first direction. Each of the plurality of chip antennas includes an antenna element and is separated in the third direction from remaining chip antennas by separation spaces. The first bracket includes first and second protrusions that protrude in the second direction to correspond to the first substrate surface of the substrate. The protrusions are aligned, in the third direction, with the separation spaces.
