Electronic device including antenna and cable structure

An electronic device comprising:

• a first housing in which a first printed circuit board (PCB) comprising a processor is disposed;
• a heat dissipation member disposed in the first housing for dissipating heat of the first printed circuit board;
• a second housing in which a second PCB comprising a display driver for a display is disposed;
• a hinge structure including a hinge rotating section and configured to physically connect the first housing and the second housing such that the first housing and the second housing are foldable/unfoldable;
• and
• a cable structure configured to electrically connect the first PCB and the second PCB via the hinge structure,
• wherein the cable structure comprises a first cable configured to transfer display signals to the second PCB and a second cable branched off from the first cable at a cable branching section between the first PCB and the hinge rotating section for grounding to the heat dissipation member.
