Description
Technical field
The present invention relates to a kind of portable device, especially relate to a kind of antenna assembly of portable device.
Background technology
Local Area Network (Local Area Network, LAN) be meant in certain zone (as: solitary building), the network of forming by the computer of a group, it can be made up of at least two or more the computers that work station is installed, and utilize cable or utilize wireless communication mode to be connected to each other, make the computer group of this Local Area Network inside, can carry out resource-sharing and data transmission by connection each other.
The computer group of present most of Local Area Network each other, all be to utilize the connecting line of cable (Cable) as the data transmission, but have following shortcoming by cable as connecting its formed Local Area Network: after a. network set up and finishes, being positioned at the computer of client (Client) if will change its position was to be not easy very much and consuming time expensive; B. formed Local Area Network then must increase or remove cable with should be required temporarily at any time if client has new computer to add or to shift out at any time, and these work all are to bother in the extreme for the user; C. with the connecting line of cable, can influence the attractive in appearance of interior of building, and in the arrangement in space, more not have elasticity as data transmission between computer group.
Thus, the research and development of wireless network (wireless LAN) technology there's no one who doesn't or isn't are devoted in communication circle at present, and attempt to make the computer group between Local Area Network carry out wireless data transmission each other with the wireless communication mode replacement with cable.
Consult shown in Figure 1, it is the circuit block diagram of wireless network card, this calcspar is to comprise an antenna 10, a radio frequency (RF) treatment element 12 and a digital signal treatment element (CODEC) 14, prerequisite element when said elements transmits with the external world by this wireless network is stuck in.Wherein, this antenna 10 mainly is the end that receives and sends as signal, and this radio frequency processing element 12 mainly is to be signal is carried out radio frequency processing, and these digital signal treatment element 14 main effects are that signal is carried out encoding and decoding.
Consult shown in Figure 2; it is the structural representation of the wireless network card 2 of known techniques; this wireless network card 2 is the hollow housing of a rectangle; it comprises an antenna 22, a radio frequency processing element and a digital signal treatment element (not shown); wherein; this radio frequency processing element and digital signal treatment element are the inside of being located at hollow housing, but in order to improve the transmission quality of signal, this wireless network card 2 can expose antenna 22 usually and protrude in hollow housing.
Yet because known techniques is to be incorporated on the computer with the wireless network card 2 that external mode will have an antenna, and this wireless network card 2 is circumscribed, so this wireless network card 2 protrudes in the computer outside with inevasible meeting.Then be that the inconvenience that all can cause the user is carried or operated to computer, especially the user of notebook computer (not shown), because it must carry wireless network card 2 at any time and carry out wireless transmission, and in the process of using, must avoid causing external wireless network card 2 to damage again at any time, this is suitable inconvenience for the user of notebook computer, therefore if can will be built in this wireless network card 2 among the notebook computer, the facility that then not only can improve the user significantly can also reduce the phenomenon that wireless network card 2 is broken.
Consult shown in Figure 3ly, it is the schematic diagram of another kind of known wireless network card 2.Be built in this wireless network card 3 on the motherboard 42 of notebook computer 4 inside, the mode of The built-in is that the antenna 32 with wireless network card 3 is formed on the motherboard 42 with plating mode, and radio frequency processing element 34 and digital signal treatment element 36 be incorporated on the motherboard 42 with the IC form, though it is little that the wireless network card 3 of in-building type has a volume, advantage such as easy to carry, but, therefore can produce screen effect and influence the signal delivery quality of wireless network card 3 widely the antenna of wireless network card 3 because at present general notebook computer 4 its shells are that magnadure and this antenna are positioned between the electronic component of printed circuit board (PCB).In addition, known techniques will be built in the wireless network card 3 on the motherboard 42 of notebook computer 4, though it is comparatively convenient but relatively it makes with cost of design also higher on carrying, and have a lot of computers itself not have built-in wireless network card 3 at present, the wireless network card of known techniques is not suitable for carrying out the expansion or the replacing of wireless network card 3 very much.
