As a result, the utility model reduces the disturbance and influence of various interfering signals in the host machine to the aerial and reduces the distance between the aerial and the wireless network card; therefore, the utility model reduces the attrition when the wireless signals communicate in the aerial, which improves the emitting power of the wireless signals and enhances the transmission performance of wireless networks of the notebook computers and simultaneously reduces the request of the inner space of the notebook computers.
Description
Technical field
The utility model relates to a kind of notebook computer, relates in particular to a kind of wireless network card and can be arranged on notebook computer on the computer display panel.
Background technology
With wireless communication technology and network technical development, the application of wireless network (802.11a/b+g WLAN) also more and more widely, wherein, for having wireless networking capabilities, wireless network card is set in notebook computer, and to replace being bought voluntarily by the user hardware configuration mode of PCMCIA wireless network card of configuration also more and more general.
As Fig. 1 and shown in Figure 2, in the prior art, the notebook computer that has wireless network card generally comprises main frame 1, wireless network card 2, antenna 3, display screen 5, display panel 6, connecting line 4.Wherein, described connecting line 4 is coaxial connecting line.Antenna 3 is arranged on the display panel 6, and links to each other with wireless network card 2 by connecting line 4.Wireless network card 2 directly is inserted on the MI NI-PCI interface slot, links to each other with main frame 1 system by the MINI-PCI bus.
In the prior art, wireless network card 2 is of a size of long 59mm, wide 44mm and thickness is the thickness of (integrated circuit (IC)-components on planar line plate+plate), be about 4-5mm, and the width of notebook computer display board 6 is about 10mm to 20mm, size than wireless network card 2 is little, therefore, wireless network card can not be arranged on the notebook display panel 6.And its adopts is PCI serial data signal interface, reaches 124PIN, so, also be not easy to be connected on the main frame 1 by connecting line.
And the slot of the MINI-PCI of existing notebook computer directly designs on mainboard, and promptly wireless network card 2 directly is plugged on the main frame 1 by described slot.At this moment if antenna 3 is arranged on the wireless network card 2, wireless signal will be subjected to the influence of the inner a large amount of undesired signals of host computer, also can be subjected to simultaneously the influence of host housing shielding, and consider that human body is to the influence of wireless signal and the radiation safety problem to human body, usually by connecting line 4 with on the suitable position that antenna 3 is guided to wireless network card 2 separates, generally be to guide on the display panel 6.
Adopt in such a way, though antenna 3 is set on the main frame display panel 6, solved the main frame internal interference signals to influence, and human body is still used the interference and the influence that can be subjected to the inner various undesired signals of main frame with the connecting line 4 that is connected to the influence of radiation signal to wireless signal in the antenna; Simultaneously, connecting line 4 itself also can cause the decay of wireless signal, the attenuation rate of the antenna of general antenna 0.8mm is at-5--6dB/m@2.4GHz, if drawing antenna from main frame is 0.3m to the distance on the display panel, will reach in the transmission attenuation rate on the antenna-more than the 1.5dB, add the influence of main frame internal interference signals, just may reach-2dB even higher, reduce the emissive power of wireless signal, influence transmission performance.
The utility model content
The utility model provides a kind of notebook computer that has wireless network card, and its purpose is to improve the emissive power of wireless signal, strengthens the transmission performance of notebook wireless network.
The utility model provides a kind of notebook computer that has wireless network card, comprise main frame, display screen, display panel, antenna, wireless network card, data bus, PCI-EXPRESS interface and connecting line, it is characterized in that: described wireless network card and antenna are arranged on the display panel, and by the connecting line connection, and described wireless network card is connected on the main frame along display panel by data bus.
Preferably, described wireless network card adopts the control chip of PCI-EXPRESS bus.
Preferably, described data bus is the PCI-EXPRESS bus.
Preferably, described wireless network card and antenna are arranged on the top of described display panel.
If when antenna was two, described antenna can be symmetricly set on the both sides of described wireless network card, perhaps described antenna and described wireless network card are separately positioned on the both sides at described display panel top.
The utility model is arranged on wireless network card on the notebook computer display panel, by the PCI-EXPRESS bus wireless network card is connected on the main frame, reduced of interference and the influence of the various noises of main frame inside to emissive source, also greatly reduce the distance between antenna and the wireless network card, therefore reduced the loss when wireless transmission signal is transmitted in antenna, make the emissive power of wireless signal be improved, strengthened the transmission performance of notebook computer wireless network, also reduced the requirement of notebook computer inner space simultaneously.

Fig. 3 is the synoptic diagram of notebook computer of the wireless network card of the PCI-EXPRESS of having bus interface of the present utility model;
Fig. 4 is the basic designed holder composition of notebook computer of the wireless network card of the PCI-EXPRESS of having bus interface of the present utility model.
Embodiment
As shown in Figure 3 and Figure 4, notebook computer of the present utility model comprises main frame 1, wireless network card 2, antenna 3, display screen 5, display panel 6, data bus 7, connecting line 4, PCI-EXPRESS interface.Antenna 3 links to each other with wireless network card 2 by connecting line 4, and antenna 3, connecting line 4, wireless network card 2 all are arranged on the notebook computer LCD display panel 6.Wherein, wireless network card 2 is connected on the PCI-EXPRESS interface on the main frame 1 by data bus 7, and the PCI-EXPRESS interface is connected on the PCI-EXPRESS control chip, as is connected on the south bridge ICH6 of ALVISO chipset.
Preferably, described data bus 7 is high-speed serial data bus (PCI-EXPRESS).(described PCI-EXPRESS is the serial bus standard of a new generation, be employed with the follow-on chipset of INTEL in,) because its employing is universal serial bus at a high speed, need less connecting line just can realize wireless network card 2 and main frame 1 transmission, as only needing four data connecting lines.Therefore, can link to each other with data bus (PCI-EXPRESS) interface by data bus 7 in the present embodiment, thereby wireless network card 2 is arranged on from main frame 1 position far away.
Preferably, wireless network card 2 can adopt the wireless network control chip with PCI-PRESS structure, and the chip of Cai Yonging is the AR5423 chip of ATHEROS in the present embodiment.Described AR5423 chip is a single-chip of supporting the PCI-EXPRESS interface of 802.11a/b+g, its size long for 7mm, it is wide that be 7mm and thickness be the thickness of the PCB+IC that generally blocks.Therefore, wireless network card 2 of the present utility model can be arranged on the display panel 6, thereby wireless network card 2 is arranged on from main frame 1 position far away,, improve the transfer efficiency of wireless signal to avoid being subjected to the interference and the influence of undesired signal in the main frame.
Therefore, when notebook designed, the utility model adopted the wireless network card 2 of PCI-EXPRESS design proposal, can easily the signal of wireless network card 2 be guided on the main frame 1 by data bus 7.Connecting line between wireless network card 2 and the antenna 34 has just shortened greatly like this, thereby solved the signal that received by antenna 3 loss problem in the connecting line 4 the wireless network card 2, under identical consumed power, improved the transmission of wireless signals efficient of notebook; And for the notebook host side saves MI NI-PCI interface slot for other functions uses, or save corresponding space, make that the design of notebook can be more frivolous, thereby satisfied the user the requirement on the notebook size aspect.
