a first housing including a first space and a conductive portion; a second housing, including a second space, slidably coupled to the first housing; a flexible display, disposed to be supported by the first housing and the second housing, having a display area that expands when being transitioned from a slide-in state to a slide-out state; a wireless communication circuit, disposed in the first space, configured to transmit or receive a wireless signal in a designated frequency band via the conductive portion; and a conductive stub disposed in the second housing to, in the slide-in state, be connectable through capacitive coupling to at least a part of the conductive portion.

2 . The electronic device of claim 1 , wherein the conductive stub is disposed in the second housing to, in the slide-out state, be electromagnetically separated from the conductive portion.

3 . The electronic device of claim 1 , wherein in the slide-in state, the conductive stub is arranged to be spaced apart from the at least the part of the conductive portion to be capable of being capacitively coupled to the at least the part of the conductive portion along a second direction perpendicular to a first direction in which the first housing slides.

4 . The electronic device of claim 1 , wherein in the slide-in state, the conductive stub is arranged to be spaced apart from the at least the part of the conductive portion to be capable of being capacitively coupled to the at least the part of the conductive portion along a first direction in which the first housing slides.

5 . The electronic device of claim 1 , wherein in the slide-in state, the conductive stub is disposed such that a first edge is capable of being capacitively coupled to a second edge of the conductive portion.

6 . The electronic device of claim 5 ,
wherein the conductive portion is segmented by at least one segmentation portion, and wherein the second edge is positioned adjacent to the at least one segmentation portion.

7 . The electronic device of claim 1 , wherein the conductive stub is electrically connected to a ground of the electronic device.

8 . The electronic device of claim 1 ,
wherein the second housing is at least partially configured of a conductive member, and wherein the conductive stub extends from the conductive member.

9 . The electronic device of claim 8 , wherein the conductive stub is integrally formed with the conductive member.

10 . The electronic device of claim 9 , wherein in the slide-in state, at least a part of the conductive portion corresponds to the conductive member and is received in the second space to not be visible, from a perspective of viewing the electronic device from outside the electronic device.
