1. An electronic device comprising:
a first housing;
a second housing connected to the first housing via a connection member to be rotatable with respect to the first housing; and
a wireless communication circuit disposed in the first housing or the second housing,
wherein the first housing comprises:
a first edge having a first length,
a first portion of the first edge is formed of a conductive material,
an insulation member is disposed at one end of the first portion, and a conductive area of the connection member is connected another end of the first portion, and
a first point of the first portion is connected to a feeding point via a capacitor having a designated value,
wherein the second housing comprises:
a second edge having a second length corresponding to the first length of the first edge,
a second portion of the second edge corresponding to the first portion is formed of a conductive material,
an opening is formed along and adjacent to the second portion,
an insulation member is disposed at one end of the second portion, and the conductive area of the connection member is connected to another end of the second portion, and
a switch is disposed between a first point of the second portion and a ground area, and
wherein the wireless communication circuit is configured to control the switch, in case that the first housing and the second housing face each other, to electrically disconnect the ground area and the first point of the second portion.
