a communication circuit disposed in the printed circuit board or on the first surface; and
a plurality of antenna units disposed in the printed circuit board or on the second surface,
wherein each of the plurality of antenna units includes:
a structure disposed on the second surface and forming an opening, the structure including a side surface surrounding at least a portion of the opening and a top surface connected to the side surface to cover the opening;
a patch type radiator disposed in the opening, the patch type radiator overlaps the top surface in a top view of the second surface of the printed circuit board; and
a feeder configured to connect the patch type radiator and the communication circuit, and
wherein the communication circuit feeds power to the feeder and transmits and receives a signal in a specified frequency band via an electrical path formed through the feeder and the patch type radiator, and
wherein the plurality of antenna units include a first antenna unit and a second antenna unit arrayed in one direction, and the side surface of the structure included in the first antenna unit and the side surface of the structure included in the second antenna unit are disposed to partially face each other.

2. The electronic device of claim 1 , wherein the side surface of the structure includes a first curved surface configured to surround at least the portion of the opening and a second curved surface disposed opposite the first curved surface with respect to the opening.

3. The electronic device of claim 2 , wherein a distance between the first curved surface and the second curved surface is greater than a diameter of the patch type radiator.

4. The electronic device of claim 1 , wherein the side surface of the structure has a cylindrical shape.

5. The electronic device of claim 1 , wherein the structure further includes a bottom surface configured to extend from the side surface of the structure in a direction parallel to the second surface.

6. The electronic device of claim 5 , wherein the bottom surface is attached to the second surface with an adhesive material.

7. The electronic device of claim 1 , wherein the top surface and the patch type radiator are separated by a specified distance.

8. The electronic device of claim 1 , wherein the patch type radiator is disposed in the printed circuit board or on the second surface.

9. The electronic device of claim 1 , wherein the printed circuit board includes a plurality of layers, and
wherein at least one of the plurality of layers includes a dielectric.

10. The electronic device of claim 1 , further comprising a pad disposed in the printed circuit board or on the second surface,
wherein the patch type radiator is disposed on the pad.

11. The electronic device of claim 1 , wherein the communication device is attached to the rear cover.

12. The electronic device of claim 1 , wherein the communication circuit transmits another signal from the patch type radiator toward the top surface.

13. The electronic device of claim 1 , further comprising a display disposed between the communication device and the cover glass, and an additional printed circuit board.

14. A communication device comprising:
a printed circuit board having a first surface and a second surface configured to face the first surface;
a plurality of antenna units disposed in the printed circuit board or on the first surface, wherein each of the plurality of antenna units including a patch type radiator disposed in the printed circuit board or on the first surface, a feeder configured to extend from the patch type radiator toward the second surface, and a structure disposed on the first surface and having an opening formed in a region corresponding to the patch type radiator, the structure including a side surface surrounding at least a portion of the opening and a top surface covering the opening; and
a communication circuit disposed in the printed circuit board or on the second surface to feed power to the feeder and transceive a signal in a specified frequency band via an electrical path formed through the feeder and the patch type radiator, and
wherein the plurality of antenna units include a first antenna unit and a second antenna unit arrayed in one direction, and the side surface of the structure included in the first antenna unit and the side surface of the structure included in the second antenna unit are disposed to partially face each other.

15. The communication device of claim 14 , wherein the side surface of the structure includes a first curved surface configured to surround at least the portion of the opening and a second curved surface disposed opposite the first curved surface with respect to the opening.

16. The communication device of claim 15 , wherein a distance between the first curved surface and the second curved surface is greater than a diameter of the patch type radiator.
