Abstract

An electronic device is provided. The electronic device comprises a housing, a flexible display configured to be at least partially rolled around a rotation axis in a substantially circular shape in an internal space of the housing, a battery located in the internal space in which the flexible display is rolled, a first printed circuit board located on one surface of the battery that is oriented in a direction of the rotation axis, the first printed circuit board being electrically connected to the flexible display and including a first wireless communication circuitry, and a second printed circuit board located inside the housing to face the first printed circuit board and including a second wireless communication circuitry. The first printed circuit board may be configured to be rotatable about the rotation axis in a state of being electrically connected to the second printed circuit board.

First claim
