Abstract

An electronic device according to various embodiments of the present disclosure may comprise: a first housing; a second housing configured to accommodate at least a portion of the first housing and to guide a sliding motion of the first housing; a flexible display including a first display area connected to the first housing, and a second display area extending from the first display area and capable of bending or rolling; a circuit board disposed in the first housing and movable in response to the sliding motion of the first housing; an antenna structure formed on an outer surface of the second structure, and including a first part and a second part that are symmetrical about a first axis perpendicular to the sliding motion direction; and a feeding structure disposed on the circuit board configured to feed power to the antenna structure. The feeding structure is electrically connected to a first point of the first part in a state in which the flexible display slides in, and the feeding structure is electrically connected to a second point of the second part in a state in which the flexible display slides out. The first point and the second point may be spaced apart from each other by the same distance as the first axis.

First claim
