Description
Technical field
The present invention relates to a kind of 3G built-in antenna improvement technology for notebook.
Background technology
At present, the built-in 3G multifrequency antenna of notebook is less towards the space, and performance is higher, more the future development of multiband integration.Most products design adds 3D form antenna that metal clips, support add FPC as representative take support in the industry, is the future development of 2D form towards the printed circuit board (PCB) form.But traditional 3D antenna can not satisfy light, thin, the little concept requirement of present notebook, and traditional printed circuit board (PCB) built-in aerial can not be positioned in the metal shell environment, and its width requirement to antenna is higher, if there is no the above height of 8mm, can't realize the satisfied beamwidth of antenna.Present 3G antenna requires more frequency range to integrate, and the frequency range that has required to cover comprises 824MHz-960MHz, 1710MHz-2170MHz; The standard that comprises has traditional GSM, CDMA and at present WCDMA, TDSCDMA, the EVDO etc. of 3G.The variation of notebook function makes the periphery electromagnetic environment of antenna more complicated, and is therefore higher to the requirement of antenna performance.Making rapid progress of notebook outward appearance, the client often in order to reach better feel and novel intention, is used for notebook computer shell to increasing metal material, makes the design difficulty of present notebook antenna increase substantially.And at present, this situation is not fixed and effective solution, and maximum square methods are by the 3G antenna being designed to the Pop-up external structure to avoid antenna metal structure on every side in the industry.
Summary of the invention
In view of this, the technical problem to be solved in the present invention be to provide a kind of design ingenious, take full advantage of metal outer frame notebook structure and realize built-in notebook 3G PCB antenna structure.
In order to solve the problems of the technologies described above, the present invention realizes in the following way:
the built-in PCB antenna structure of a kind of 3G for notebook, the antenna body radiation fin and the antenna body that comprise printed circuit board base board and be arranged on circuit board substrate encourage sheet, described circuit board substrate is rectangle, this circuit board substrate is installed in opening default on the notebook metal outer frame, offering along its length on the body radiation fin by body encourages sheet can produce the conduit of the first resonance, having by body between body radiation fin and notebook housing encourages sheet can produce the gap of the second resonance, weld between the cable of connection notebook internal circuit and body excitation sheet.And described conduit runs through body radiation fin one end, and body radiation fin integral body is U-shaped.
Wherein, described the first resonant frequency range is 824MHz-960MHz, and described the second resonant frequency range is 1710MHz-2170MHz.
Wherein, described body excitation sheet is L-type.
The present invention slots by the gap and the notebook metal outer frame is coupled produces effective low-and high-frequency resonance of antenna, avoided the traditional metal housing to adverse effects such as the coupling of aerial radiation, absorptions, for design notebook 3G antenna in the metal environment becomes possibility, and provide a feasible and effective scheme.Mentality of designing of the present invention is simple and clear, and desin speed is fast, adjusts flexibly, and effectively, and antenna product only used printed circuit board (PCB), and is simple in structure, with low cost, and has very strong originality and practicality.The present invention successfully is used in actual items, and is proved and has greatly improved antenna performance and efficiency of research and development.

Embodiment
Defective for prior art exists is described in further detail of the present invention for the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing:
As shown in accompanying drawing 1～3, the built-in PCB antenna structure of 3G that is used for notebook of the present embodiment design, the antenna body radiation fin 2 and the inverted-L antenna body that comprise printed circuit board base board 1 and be arranged on circuit board substrate 1 encourage sheet 3, connect heart yearn and 3 welding of body excitation sheet of the coaxial cable 5 of notebook internal circuit, the screen of coaxial cable 5 is electrically connected to body radiation fin 2.Wherein, circuit board substrate 1 is rectangle, this circuit board substrate 1 is installed in opening 41 default on notebook metal outer frame 4, offering along its length on body radiation fin 2 by body encourages sheet 3 can produce the conduit 21 of the first resonance, this conduit 21 runs through body radiation fin 2 one ends, makes body radiation fin 2 whole for U-shaped.Having between body radiation fin 2 and notebook housing 4 by body encourages sheet 3 can produce the gap 22 of the second resonance.In this programme, the first resonant frequency range is 824MHz-960MHz, and the second resonant frequency range is 1710MHz-2170MHz.
Again in detail as shown in accompanying drawing 4,5, the lamellar body 22 of body radiation fin 2,23(see dotted line frame in Fig. 4) part and edge 41, the 42(of metal outer frame 4 see in Fig. 4 dotted line frame in addition) part carries out close coupling, makes lamellar body 22,23 and metal outer frame 4 integral body of form in theory.Antenna body radiation fin 4 encourages sheet 3 for to have the U-shaped of conduit 21 by antenna body, produces antenna the first resonance, frequency range 824MHz-960MHz; Antenna body radiation fin 2 again and have gap 22 between metal outer frame 4 encourages sheet 3 by antenna body, produces second resonance of antenna, frequency range 1710MHz-2170MHz, thus consist of 3G multifrequency integral antenna.
The present invention utilizes the basic principle of slot antenna, reduces metal ground around antenna to the impact of antenna, and theoretical in conjunction with antenna-coupled, an ingenious part of utilizing metal outer frame to make it to consist of antenna, generation another one gap.Antenna is originally as coupling slot gap antenna form, adopt double-layer printing circuit board, penetrate sheet by a single width and produce the signal excitation, the gap generation of antenna the first resonance own is low-frequency resonant, and it is high-frequency resonant that the gap between antenna and metal outer frame mainly produces the second resonance.And utilize the peripheral width of antenna slots to penetrate sheet with the metal outer frame coupling, make antenna and metal outer frame become in theory as a whole, the unfavorable factor in space is converted into favorable factor to antenna.
The above embodiment has only expressed embodiments of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.Should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise; can also make some distortion and improvement; its range of application can be other telecommunications products, and as mobile phone and other equipment etc. first, these all belong to protection scope of the present invention.
