Abstract

According to one embodiment, an electronic device includes a housing including a bottom wall and a side wall rising from an circumference of the bottom wall, an antenna formed on inner surface of the housing, and a part contained inside the housing and having a radio wave absorption property. The part having a radio wave absorption property is arranged with a predetermined gap maintained relative to the side wall of the housing, and at least a part of the antenna is formed in tight contact with an inner surface of the side wall of the housing.

Claims

1. An electronic device comprising:

a housing comprising a bottom wall and a side wall rising from a circumference of the bottom wall;

an antenna provided on an inner surface of the housing; and

a component having a radio wave absorption property inside the housing,

wherein

the component is positioned a predetermined distance from the side wall of the housing; and

at least a part of the antenna is in substantially tight contact with an inner surface of the side wall of the housing.

2. The electronic device of claim 1, wherein the antenna further comprises:

an antenna element formed in substantially tight contact with the inner surface of the side wall; and

an antenna ground formed in substantially tight contact with an inner surface of the bottom wall.

3. The electronic device of claim 2, further comprising:

a wireless module inside the housing; and

a wiring portion configured to connect the antenna and the wireless module to each other;

wherein at least a part of the wiring portion is in substantially tight contact with the side wall and the bottom wall of the housing.

4. The electronic device of claim 3, wherein the antenna and at least a part of the wiring portion are formed by printing on the inner surface of the housing.

5. The electronic device of claim 4, wherein the housing further comprises:

a main body cabinet configured to hold the wireless module; and

a display cabinet comprising the bottom wall and the side wall rising from the circumference of the bottom wall and holding a display,

wherein

the component having a radio wave absorption property is the display; and

the antenna is formed on an inner surface of the display cabinet.

6. The electronic device of claim 5, wherein the display cabinet further comprises:

a mask facing a front surface of the display; and

a cover comprising the bottom wall and the side wall facing a rear surface of the display.

7. The electronic device of claim 4, wherein

the housing is configured to hold the wireless module, the display and the component having a radio wave absorption property, altogether;

and

the component is a disk device configured to read and write data from a disk-like recording medium.

8. The electronic device of claim 7, wherein the housing comprises:

a first portion with a top wall; and

a second portion with a bottom wall opposing the top wall and the side wall.
