Embodiment
The following describes portable electronic device and radio communication device thereof that the embodiment of the present invention proposes.In one embodiment of this invention, portable electronic device for example but not can be limitedly a notebook computer.Be described as follows as an example of the portable electronic device that is applied to notebook computer example.
Please refer to Figure 1A and Figure 1B.Figure 1A illustrates the schematic diagram according to an example of the portable electronic device that is applied to notebook computer 100 of one embodiment of the invention.Figure 1B is depicted as the profile of Figure 1A along line segment A and A '.Portable electronic device 100 comprise one first housing 110, one second housing 120, a control unit 112, a display unit 122, with a radio communication device 300.
Two housings 110 and 120 rotatably couples mutually.In one embodiment, portable electronic device 100 can separately comprise a hinge 140, and it rotatably couples the first housing 110 to second housings 120.So, correspond to the rotating manner of hinge 140, the two housings 110 and 120 of portable electronic device 100 just can present the state of closure or openness.For instance, the two housings 110 and 120 shown in Figure 1A presents the state of unlatching.
As shown in Figure 1B, control unit 112 is contained among the first housing 110.122 of display units are to be contained among the second housing 120, and radio communication device 300 is also contained among the second housing 120.Display unit 122 is connected to control unit 112.
Hereby by the portable electronic device of the present embodiment 100 and tradition by wireless communication module be arranged on compare near control unit 112 and the notebook computer far away apart from antenna as follows, to illustrate that the present embodiment is had advantages of.
First, in tradition, wireless communication module 310 is arranged in the first housing 110, and is connected with control unit 112.But in the portable electronic device 100 of the present embodiment, wireless communication module 310 can be arranged in the second housing 120 and near antenna 320 parts, therefore wireless communication module 310 can reduce with the distance of antenna 320.So, can reduce the aerial signal decay between wireless communication module 310 and antenna 320.
