Description

BACKGROUND FIELD Various embodiments of the disclosure relate to an electronic device. DESCRIPTION OF RELATED ART In electronic devices, a use of a metal frame is preferred for their mechanical rigidity or high-end design. For example, an electronic device that serves wireless communication, such as e.g., a smart phone, may provide a segment or segmented part in its metal frame, and utilize the metal frame provided with such a segmented part as an antenna. For the electronic device using the metal frame as an antenna, radiation energy may be concentrated around the segment arranged in the metal frame, and thus, when a metal dielectric is present adjacent to the segment, it may lead to an increased coupling factor in the metal dielectric. When the coupling factor increases, the antenna efficiency in an electronic device may be reduced. Therefore, it may be more advantageous in securing better antenna performance to arrange a metallic material to be spaced apart from the segment of the metal frame as much as possible in its design. US 2021/168973 Al discloses an electronic device including a housing, and a display disposed to at least part of the housing. The display includes a display panel including at least one pixel, and a substrate layer disposed below the display panel. The substrate layer includes a bendable connecting area extending to the outside of the display panel. The display further includes a display driving circuit disposed to one face of the connecting area, a Flexible Printed Circuit Board (FPCB) electrically coupled with at least part of the connecting area and including a contact area to which a conductor electrically coupled with a ground portion of the electronic device is exposed, and a shielding member electrically coupled with the contact area. The shielding member is disposed on the FPCB and one face of the connecting area to cover at least part of the display driving circuit.
