Embodiment
The following describes portable electronic device and radio communication device thereof that the embodiment of the invention proposes.In one embodiment of this invention, portable electronic device for example but not can be a notebook computer limitedly.With the portable electronic device that is applied to notebook computer is that example is described as follows.
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 section along the line 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 comprise a hinge 140 in addition, and it rotatably couples 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 shown in Figure 1A 110 and 120 presents the state of unlatching.
Shown in Figure 1B, control unit 112 is contained among first housing 110.122 of display units are to be contained among second housing 120, and radio communication device 300 also is contained among second housing 120.Display unit 122 is connected to control unit 112.
Now with the portable electronic device 100 of present embodiment and tradition with wireless communication module be arranged on compare near control unit 112 and the notebook computer far away apart from antenna as follows, with the explanation advantage that present embodiment was had.
At first, in the tradition, wireless communication module 310 is arranged in first housing 110, and is connected with control unit 112.Yet in the portable electronic device 100 of present embodiment, wireless communication module 310 can be arranged in second housing 120 and close antenna 320 parts, so the distance of wireless communication module 310 and antenna 320 can reduce.So, the aerial signal that can reduce between wireless communication module 310 and the antenna 320 is decayed.
