Abstract

An electronic device may include a housing including a first plate facing a first direction, a second plate facing a second direction opposite the first direction, and a side housing surrounding a space between the first plate and the second plate, wherein the side housing includes a first portion, including an external metal portion having a first face facing an outside and a second face facing the space and an internal polymer portion having a third face contacting the second face and a fourth face facing the space, a touch screen display positioned within the space to be viewable through the first plate, wherein an edge of the touch screen display is spaced apart from the first portion of the side housing and when the first plate is viewed from above, the gap is covered by a peripheral portion of the first glass plate, an antenna structure comprising at least one antenna and configured to include a substrate having a fifth face substantially parallel to the second face and a sixth face facing a direction opposite the fifth face and at least one conductive pattern positioned between the fifth face and the sixth face and extending toward the peripheral portion of the first plate, and wireless communication circuitry operatively connected to the at least one conductive pattern and configured to form a directivity beam using at least a part of the at least one conductive pattern.

First claim

What is claimed is:

1. An electronic device, comprising:
a housing comprising a first plate facing a first direction, a second plate facing a second direction opposite the first direction, and a side housing surrounding a space between the first plate and the second plate, wherein the side housing comprises a first portion, comprising an external metal part having a first face facing an outside and a second face facing the space and an internal polymer portion having a third face contacting the second face and a fourth face facing the space;
a touch screen display positioned within the space to be viewable through the first plate, wherein an edge of the touch screen display includes a gap from the first portion of the side member, wherein the gap is covered by a peripheral portion of the first plate when the first plate is viewed from above;
an antenna structure comprising at least one antenna and comprising a substrate having a fifth face substantially parallel to the second face and a sixth face facing a direction opposite the fifth face and at least one conductive pattern positioned between the fifth face and the sixth face and extending toward the peripheral portion of the first plate; and
wireless communication circuitry operatively connected to the at least one conductive pattern and configured to form a directivity beam using at least a part of the at least one conductive pattern.

2. The electronic device of claim 1 , wherein the sixth face is substantially vertical to the touch screen display.

3. The electronic device of claim 1 , wherein the sixth face forms an acute angle with the touch screen display.

4. The electronic device of claim 1 , wherein:
the first plate comprises a planar portion, and
the peripheral portion of the first plate is bent from the planar portion.

5. The electronic device of claim 1 , wherein the at least one conductive pattern is positioned at least partially within the gap.

6. The electronic device of claim 1 , wherein at least part of the at least one conductive pattern is positioned at a location overlapping the internal polymer portion when the side member is viewed from above.

7. The electronic device of claim 1 , wherein:
the conductive pattern is positioned at a location overlapping at least a portion of an area of the touch screen display when the first plate is viewed from above, and
the substrate forms an acute angle with the touch screen display directed toward the gap.

8. The electronic device of claim 1 , wherein the display further comprises a cutting portion from which an area overlapping the conductive pattern is not visible when the first plate is viewed from above.

9. The electronic device of claim 8 , wherein the cutting portion is positioned in a black matrix (BM) area of the touch screen display.

10. The electronic device of claim 1 , further comprising:
a printed circuit board (PCB) positioned in the space and spaced apart from the substrate; and
a conductive cable configured to electrically connect the PCB and the at least one conductive pattern of the substrate.

11. The electronic device of claim 10 , wherein the wireless communication circuitry is positioned in the PCB.

12. The electronic device of claim 10 , further comprising at least one conductive patch positioned on one side of the PCB,
wherein the wireless communication circuitry forms a directivity beam having a direction different from a direction of the conductive pattern using the conductive patch.

13. The electronic device of claim 12 , wherein the wireless communication circuitry is configured to:
form a directivity beam in a direction in which the first plate faces using the conductive pattern, and
form a directivity beam in a direction in which the second plate faces using the conductive patch.

14. The electronic device of claim 12 , wherein the wireless communication circuitry is configured to transmit and/or receive a radio frequency in a range of about a 3 GHz˜100 GHz through the at least one conductive patch.

15. The electronic device of claim 10 , further comprising a support positioned to support the PCB and/or the substrate within the space.

16. The electronic device of claim 15 , wherein the support comprises a dielectric material.

17. The electronic device of claim 15 , further comprising at least one conductive electronic part positioned within the space,
wherein the support is positioned between the conductive electronic part and the PCB and/or the substrate.

18. The electronic device of claim 15 , wherein the support comprises:
a first support configured to support the substrate; and
a second support extending from the first support and configured to support the PCB,
wherein an angle between the substrate and the touch screen display is determined by a shape of the first support.

19. The electronic device of claim 18 , wherein the substrate comprises a flexible printed circuit board (FPCB) supported by the first support.

20. The electronic device of claim 1 , wherein the wireless communication circuitry is configured to transmit and/or receive a radio frequency in a range of about a 3 GHz˜100 GHz through the at least one conductive pattern.
