Abstract

An electronic device is provided. The electronic device includes a housing that includes a slit, a first antenna element extending along a portion of the housing, a second antenna element spaced apart from at least a portion of the first antenna element by the slit and extends along another portion of the housing, and a wireless communication circuit positioned inside the housing and electrically connected to the first antenna element. The first antenna element is electrically connected to the second antenna element.

First claim

What is claimed is:

1. An electronic device comprising:
a housing including a slit;
a first antenna element extending along a portion of the housing;
a second antenna element spaced apart from at least a portion of the first antenna element by the slit, and extending along another portion of the housing;
a wireless communication circuit positioned inside the housing, and electrically connected to the first antenna element; and
a switch configured to:
adjust an open/close of an electrical path connecting the first antenna element and the second antenna element, and
selectively connect the first antenna element and the second antenna element,

wherein a length of the slit is reduced based on the first antenna element being electrically connected to the second antenna element by the switch.

2. The electronic device of claim 1 , further comprising:
a printed circuit board positioned inside the housing,
wherein the first antenna element is connected to a ground part positioned at the printed circuit board through a first point of the first antenna element.

3. The electronic device of claim 1 , wherein the second antenna element is connected to a ground part through a first point of the second antenna element.

4. The electronic device of claim 3 , further comprising:
a printed circuit board positioned inside the housing,
wherein the ground part is positioned at the printed circuit board.

5. The electronic device of claim 3 , further comprising:
a ground region formed along a portion of the housing,
wherein the ground part is positioned in the ground region.

6. The electronic device of claim 2 ,
wherein a first point of the switch is connected to a second point of the first antenna element distinguished from the first point of the first antenna and a second point of the switch is connected to the ground part.

7. The electronic device of claim 1 ,
wherein the electrical path connects a first point of the first antenna element and a second point of the second antenna element, and
wherein the first point and the second point are adjacent to the slit.

8. The electronic device of claim 7 , wherein the first point and the second point face each other, with the slit interposed between the first point and the second point.

9. The electronic device of claim 1 , further comprising:
a printed circuit board positioned inside the housing,
wherein the switch is positioned on the printed circuit board.

10. The electronic device of claim 9 , wherein the switch is positioned in a fill cut region of the printed circuit board.

11. The electronic device of claim 1 ,
wherein the switch includes a radio frequency (RF) port, and
wherein the first antenna element and the second antenna element are connected to the RF port of the switch.

12. The electronic device of claim 1 , wherein the wireless communication circuit is configured to:
transmit or receive a signal of a first frequency to or from an external device through the first antenna element when the switch is opened, and
transmit or receive a signal of a second frequency to or from an external device through the first antenna element and the second antenna element when the switch is closed.

13. The electronic device of claim 12 , wherein the second frequency is higher than the first frequency.

14. An electronic device comprising:
a housing including:
a first plate,
a second plate facing away from the first plate, and
a side member surrounding a space between the first plate and the second plate, the side member including:
a first side extending in a first direction and having a first length,
a second side extending in a second direction perpendicular to the first direction and having a second length shorter than the first length,
a third side extending in parallel to the first side and having the first length,
a fourth side extending in parallel to the second side and having the second length, and
an elongated slit extending from a first point in the first side to a second point in the third side along a portion of the first side, the second side, and a portion of the third side, and
a non-conductive material filling the slit;

a touchscreen display exposed through at least a portion of the first plate;
a ground plane positioned in the housing in parallel to the second plate, and electrically coupled to a third point of the first side at or near the first point;
a wireless communication circuit positioned inside the housing and electrically coupled to a fourth point positioned in one of the portion of the first side, the second side, or the portion of the third side;
at least one processor positioned inside the housing and electrically connected to the display and the communication circuit;
an electrically conductive member electrically coupled between a fifth point and a sixth point of the side member, wherein the fifth point and the sixth point are positioned between the third point and the fourth point, when viewed from above the second plate, and on opposite sides of the slit; and
a switching element positioned inside the housing and electrically connected to the fifth point and the sixth point,
wherein a substantial portion of the second plate is formed of an electrically conductive material, and
wherein the side member is formed of an electrically conductive material.

15. The electronic device of claim 14 , wherein the wireless communication circuit provides at least one of a global positioning system (GPS) signal, a Wi-Fi signal, or a Bluetooth signal.

16. The electronic device of claim 14 , further comprising:
a printed circuit board positioned inside the housing,
wherein the switching element is positioned at the printed circuit board.

17. The electronic device of claim 14 , further comprising:
a flexible conductive member coupled to at least one of the fifth point or the sixth point.

18. The electronic device of claim 14 , wherein the second plate is electrically connected to the ground plane.

19. An electronic device comprising:
a housing including:
a first plate,
a second plate facing away from the first plate,
a side member surrounding a space between the first plate and the second plate, the side member including:
