Abstract

A wireless device includes: a casing having a first face; a display configured to be visible from the first face; a touch sensor formed by a transparent material and mounted in the casing with respect to the display as a part of the first face; a substrate mounted to a side opposite to the first face with respect to the display; and an antenna element including: a first portion built in the casing, connected to a feeding point included in the substrate, and located within a first range occupied by the touch sensor when viewed from a direction perpendicular to the first face; and a second portion located within a second range other than the first range.

Claims

1. A wireless device comprising:

a casing having a first face;

a display configured to be visible from the first face;

a touch sensor formed by a transparent material and mounted in the casing with respect to the display as a part of the first face;

a substrate mounted to a side opposite to the first face with respect to the display; and

an antenna element including;

a first portion built in the casing, connected to a feeding point included in the substrate, and located within a first range occupied by the touch sensor when viewed from a direction perpendicular to the first face; and

a second portion located within a second range other than the first range.

2. The wireless device of claim 1, wherein:

current of a relatively large amplitude is distributed at the first portion when power is fed, and

voltage of a relatively large amplitude is distributed at the second portion when power is fed.

3. The wireless device of claim 1, wherein

the antenna element includes a portion extending from the feeding point in a direction away from the first face.

4. The wireless device of claim 1, comprising a conductive member arranged between the first portion of the antenna element and the touch sensor.

5. The wireless device of claim 1, wherein

the antenna element includes an open-ended monopole antenna, a folded monopole antenna, and an inverted-F antenna.

6. The wireless device of claim 1, wherein:

the first face has a shape of a rectangle, and

the antenna element is mounted in a vicinity of one short side of the rectangle.

7. The wireless device of claim 6, further comprising an antenna element mounted in the vicinity of the one short side of the rectangle.

8. The wireless device of claim 6, further comprising an antenna element mounted in a vicinity of the other short side of the rectangle.

9. A wireless device comprising:

a casing having a first face;

a touch panel including a display and a touch sensor, the touch panel being a part of the first face;

a substrate in the casing; and

an antenna element in the casing including;

a first portion connected to a feeding point included in the substrate, and located within a first range occupied by the touch panel when viewed from a direction perpendicular to the first face; and

a second portion located within a second range other than the first range.

10. The wireless device of claim 9, wherein:

current of a relatively large amplitude is distributed at the first portion when power is fed, and

voltage of a relatively large amplitude is distributed at the second portion when power is fed.

11. The wireless device of claim 9, wherein

the antenna element includes a portion extending from the feeding point in a direction away from the first face.

12. The wireless device of claim 9, comprising a conductive member arranged between the first portion of the antenna element and the touch panel.

13. The wireless device of claim 9, wherein

the antenna element includes an open-ended monopole antenna, a folded monopole antenna, and an inverted-F antenna.

14. The wireless device of claim 9, wherein:

the first face has a shape of a rectangle, and

the antenna element is mounted in a vicinity of one short side of the rectangle.

15. The wireless device of claim 14, further comprising an antenna element mounted in the vicinity of the one short side of the rectangle.

16. The wireless device of claim 14, further comprising an antenna element mounted in a vicinity of the other short side of the rectangle.
