Abstract

According to one embodiment, an electronic apparatus includes a display device with a display screen, a first wireless communication module, a second wireless communication module, first antennas for the first wireless communication module, and second antennas for the second wireless communication module. The display screen is exposed from a front surface of a housing. At least two of each of the first antennas and the second antennas are disposed in two perpendicular sides of the housing. The two perpendicular sides are peripheral parts of the display screen. One of the first antennas disposed in the two perpendicular sides and one of the second antennas disposed in the two perpendicular sides are disposed in respective center parts of the two perpendicular sides.

Claims

1. An electronic apparatus comprising:

a display device with a display screen, the display screen exposed from a front surface of a housing;

a first wireless communication module;

a second wireless communication module;

first antennas for the first wireless communication module; and

second antennas for the second wireless communication module, wherein;

at least two of each of the first antennas and the second antennas are disposed in two perpendicular sides of the housing, the two perpendicular sides being peripheral parts of the display screen, and

one of the first antennas disposed in the two perpendicular sides and one of the second antennas disposed in the two perpendicular sides are disposed in respective center parts of the two perpendicular sides.

2. The apparatus of claim 1, wherein the one of the first antennas disposed in the center part of a first side of the two perpendicular sides and the one of the second antennas disposed in the center part of a second side of the two perpendicular sides comprise antennas for transmission or antennas for transmission and reception.

3. The apparatus of claim 2, wherein:

the other first antenna than the one of the first antennas disposed in the center part of the first side of the two perpendicular sides is disposed in a first part of the second side of the two perpendicular sides, the first part is distant from the first side of the two perpendicular sides beyond the center part where the one of the second antennas is disposed, and

the other second antenna than the one of the second antennas disposed in the center part of the second side of the two perpendicular sides is disposed in a second part of the first side of the two perpendicular sides, the second part is distant from the second side of the two perpendicular sides beyond the center part where the one of the first antennas is disposed.

4. The apparatus of claim 1, wherein the other first antenna than the one of the first antennas disposed in the center part of the first side of the two perpendicular sides and the other second antenna than the one of the second antennas disposed in the center part of the second side of the two perpendicular sides comprise antennas for reception.

5. The apparatus of claim 1, further comprising:

a battery; and

a connector configured to receive electrical energy used for charging the battery,

wherein either the first side of the two perpendicular sides or the second side of the two perpendicular sides comprises a side of the housing, which is opposed to a side of the housing, in which the connector is disposed.

6. The apparatus of claim 1, further comprising an operation key mounted on the front surface of the housing,

wherein the first side of the two perpendicular sides and the second side of the two perpendicular sides comprise sides of the housing, which are different from a side of the housing, in which the operation key is disposed.

7. The apparatus of claim 1, further comprising:

a battery; and

a wireless charging antenna configured to charge the battery in an electrically noncontacting state,

wherein the wireless charging antenna is disposed in a corner of the housing, the corner being opposed to a corner of the housing, at which the first side of the two perpendicular sides and the second side of the two perpendicular sides cross each other.

8. The apparatus of claim 7, wherein the wireless charging antenna is formed as a rectangle, and is disposed such that a first side of the wireless charging antenna runs along a side of the housing, which is opposed to the first side of the two perpendicular sides, and a second side of the wireless charging antenna which is perpendicular to the first side of the wireless charging antenna runs along a side of the housing, which is opposed to the second side of the two perpendicular sides.

9. The apparatus of claim 7, wherein the wireless charging antenna is formed in an L-shape with a first part and a second part that is perpendicular to the first part, and is disposed such that the first part of the wireless charging antenna runs along a side of the housing, which is opposed to the first side of the two perpendicular sides, and the second part of the wireless charging antenna runs along a side of the housing, which is opposed to the second side of the two perpendicular sides.

10. An electronic apparatus comprising:

a display device with a display screen, the display screen exposed from a front surface of a housing;

a first wireless communication module;

a second wireless communication module;

first antennas for the first wireless communication module; and

second antennas for the second wireless communication module, wherein;

at least two of each of the first antennas and the second antennas are disposed in two perpendicular sides of the housing, the two perpendicular sides being peripheral parts of the display screen, and

either one of the first antennas disposed in the two perpendicular sides or one of the second antennas disposed in the two perpendicular sides is disposed in a center part of one of the two perpendicular sides.

11. The apparatus of claim 10, wherein

the either one of the first antennas disposed in the two perpendicular sides or one of the second antennas disposed in the two perpendicular sides, which is disposed in the center part of one of the two perpendicular sides comprises an antenna for transmission or an antenna for transmission and reception.
