Abstract

Claims (45)

1 . An electronic device comprising:

a first housing comprising:

a first surface; and

a second surface connected to the first surface and having an area that is smaller than an area of the first surface;

a second housing comprising:

a third surface; and

a fourth surface connected to the third surface and having an area that is smaller than an area of the third surface;

a hinge structure connecting the first housing and the second housing to be foldable relative to each other at a folding axis, between a folded state of the electronic device and an unfolded state of the electronic device;

a first antenna array provided at the second surface;

a second antenna array provided at the fourth surface; and

a flexible board connecting the first antenna array and the second antenna array, wherein the first antenna array and the second antenna array are configured to form a third antenna array and to form a fourth antenna array, according to whether the electronic device is in the unfolded state or in the folded state.

2 . The electronic device of claim 1 , wherein the first antenna array and the second antenna array are configured to form the third antenna array when the electronic device is in the unfolded state, and

wherein the first antenna array and the second antenna array are configured to form the fourth antenna array when the electronic device is in the folded state.

3 . The electronic device of claim 1 , wherein, when the electronic device is in the unfolded state, the first antenna array and the second antenna array are arranged along an axis that is perpendicular to the folding axis to form the third antenna array.

4 . The electronic device of claim 1 , wherein, when the electronic device is in the folded state, the first antenna array and the second antenna array are arranged along an axis that is perpendicular to the folding axis to form the fourth antenna array.

5 . The electronic device of claim 1 , wherein the first antenna array and the second antenna array have a 1×n arrangement, where n is a natural number.

6 . The electronic device of claim 5 , wherein the third antenna array has a 1×2n arrangement.

7 . The electronic device of claim 5 , wherein the fourth antenna array has a 2×n arrangement.

8 . The electronic device of claim 1 , wherein the flexible board connects a first side surface of the first antenna array and a second side surface of the second antenna array, and

wherein the first side surface of the first antenna array and the second side surface of the second antenna array correspond to each other when the electronic device is in the unfolded state.

9 . An electronic device comprising:

an antenna structure; and

a communication circuit electrically connected to the antenna structure,

wherein the antenna structure includes:

a first housing comprising:

a first surface; and

a second surface connected to the first surface;

a second housing comprising:

a third surface; and

a fourth surface connected to the third surface;

a hinge structure connecting the first housing and the second housing to be foldable relative to each other at a folding axis, between a folded state of the electronic device and an unfolded state of the electronic device;

a first antenna array provided at the second surface;

a second antenna array provided at the fourth surface; and

a flexible board connecting the first antenna array and the second antenna array, and

wherein the first antenna array and the second antenna array are configured to form a third antenna array and to form a fourth antenna array according to whether the electronic device is in the unfolded state or in the folded state.

10 . The electronic device of claim 9 , wherein the communication circuit is configured to operate at least one of the first antenna array and the second antenna array.

11 . The electronic device of claim 9 , wherein the communication circuit is provided on a surface of any one of the first antenna array and the second antenna array.

12 . The electronic device of claim 9 , wherein the communication circuit is configured to:

steer a beam formed from the third antenna array along an axis that is perpendicular to the folding axis when the electronic device is in the unfolded state; and

steer a beam formed from the fourth antenna array along the axis that is perpendicular to the folding axis when the electronic device is in the folded state.

13 . The electronic device of claim 9 , wherein the communication circuit is configured to:

steer a beam formed from the third antenna array along the folding axis or an axis that is perpendicular to the folding axis when the electronic device is in the unfolded state; and

steer a beam formed from the first antenna array and a beam formed from the second antenna array along the folding axis when the electronic device is in the folded state.

14 . The electronic device of claim 9 , wherein the flexible board connects a side surface of the second surface and a side surface of the fourth surface, and

wherein the communication circuit is provided on a surface opposite to the second surface or the fourth surface.
