a first printed circuit board interposed between the display and the intermediate plate;

a first electronic component attached to a first portion of the second face;

a second electronic component attached to a second portion, away from the first portion, of the second face; and

a first heat-dissipating structure extended between the first portion and the second portion along the second face.

2. The electronic device of claim 1 , wherein the first heat-dissipating structure includes a layer and/or heat pipe formed of at least one of copper, aluminum, stainless steel (SUS), and graphite.

3. The electronic device of claim 1 , further comprising a second printed circuit board and third printed circuit board fixed on the second face.

4. The electronic device of claim 3 ,

wherein the first electronic component is interposed between the first portion and the second printed circuit board, and

wherein the second electronic component is interposed between the second portion and the third printed circuit board.

5. The electronic device of claim 4 , further comprising: a first adhesive layer between the first electronic component and the first portion; and a second adhesive layer between the second electronic component and the second portion.

6. The electronic device of claim 5 ,

wherein the second printed circuit board includes a first array antenna electrically connected with the first electronic component, and

wherein the third printed circuit board includes a second array antenna electrically connected with the second electronic component.

7. The electronic device of claim 6 , wherein the first antenna array and the second antenna array are respectively disposed at both corner portions of one lateral face of the electronic device.

8. The electronic device of claim 7 , further comprising:

a third antenna array and fourth antenna array disposed respectively at both corner portions of the other lateral face opposite to the one lateral face; and

a third heat-dissipating structure extended between the third array antenna and the fourth antenna array.

9. The electronic device of claim 6 ,

wherein the first electronic component includes a first radio frequency circuit, and the second electronic component includes a second radio frequency circuit, and

wherein the electronic device further comprises a third radio frequency circuit mounted on the first printed circuit board, and the third radio frequency circuit is configured to provide an intermediate frequency signal alternately to the first radio frequency circuit and the second radio frequency circuit.

10. The electronic device of claim 9 , wherein the first radio frequency circuit and the second radio frequency circuit are configured to generate a signal having a frequency in the range of 20 GHz to 60 GHz.

11. The electronic device of claim 7 , further comprising a second heat-dissipating structure thermally connected with the third radio frequency circuit, wherein the second heat-dissipating structure includes a layer, heat pipe, and/or cooling fan formed of at least one of copper, aluminum, stainless steel (SUS), and graphite.

12. The electronic device of claim 9 ,

wherein the first array antenna is disposed to a face facing the rear plate in the second printed circuit board, and the first radio frequency circuit is disposed to a face facing the second face in the second printed circuit board;

wherein the first electronic component includes a shield can enclosing the first radio frequency circuit, and

wherein the shield can is attached to the first portion, and a Thermal Interface Material (TIM) is interposed between the shield can and the first portion.

13. The electronic device of claim 12 ,

wherein the first array antenna includes a directional first antenna and a non-directional second antenna, and

wherein the shield can is located not to overlap with a region to which the second antenna is disposed, when the second printed circuit board is viewed from above.

14. The electronic device of claim 13 , wherein the heat-dissipating structure has a shape conforming to an edge of the shield can which is in contact with the region to which the second antenna is disposed.

15. The electronic device of claim 1 , wherein the first electronic component, the second electronic component, and the first heat-dissipating structure are disposed along one lateral face of the housing.
