Description
[technical field]
The present invention relates to a kind of 3G built-in antenna improvement technology that is used for notebook.
[background technology]
At present, the built-in 3G multifrequency antenna of notebook is littler towards the space, and performance is higher, and more the direction of multiband integration develops.It is representative that most of in the industry product designs add the 3D form antenna that metal clips, support add FPC with support, is that the direction of 2D form develops 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 to the width requirement of antenna than higher, if do not have 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 that the periphery electromagnetic environment of antenna is complicated more, 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, the unfixing and effective solution of this situation, maximum in the industry square methods are by the 3G antenna being designed to the Pop-up external structure to avoid antenna metal structure on every side.
[summary of the invention]
In view of this, the technical problem to be solved in the present invention provide a kind of design ingenious, make full use 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:
A kind of built-in PCB antenna structure of 3G that is used for notebook, the antenna body radiation fin and the antenna body that comprise printed circuit board base board and be arranged on the circuit board substrate encourage sheet, described circuit board substrate is a rectangle, this circuit board substrate is installed in the opening default on the notebook metal outer frame, on the body radiation fin, offer the conduit that can produce first resonance by body excitation sheet along its length, between body radiation fin and notebook housing, have the slit that can produce second resonance, weld between the cable of connection notebook internal circuit and the body excitation sheet by body excitation sheet.And described conduit runs through body radiation fin one end, and body radiation fin integral body is the U type.
Wherein, described first resonant frequency range is 824MHz-960MHz, and described second resonant frequency range is 1710MHz-2170MHz.
Wherein, described body excitation sheet is the L type.
The present invention produces effective low-and high-frequency resonance of antenna by slit fluting and the coupling of notebook metal outer frame, avoided the conventional metals 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 the actual items, and is proved and has improved antenna performance and efficiency of research and development greatly.

[embodiment]
Defective at prior art exists describes 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:
Shown in accompanying drawing 1～3, the built-in PCB antenna structure of the 3G that is used for notebook of 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 the circuit board substrate 1 encourage sheet 3, connect the 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 with body radiation fin 2.Wherein, circuit board substrate 1 is a rectangle, this circuit board substrate 1 is installed in the opening 41 default on the notebook metal outer frame 4, on body radiation fin 2, offer the conduit 21 that can produce first resonance by body excitation sheet 3 along its length, this conduit 21 runs through body radiation fin 2 one ends, makes body radiation fin 2 integral body be the U type.Between body radiation fin 2 and notebook housing 4, has the slit 22 that can produce second resonance by body excitation sheet 3.In this programme, first resonant frequency range is 824MHz-960MHz, and second resonant frequency range is 1710MHz-2170MHz.
Again in detail shown in accompanying drawing 4,5, lamellar body 22,23 (seeing frame of broken lines among Fig. 4) part of body radiation fin 2 is carried out close coupling with the edge 41,42 of metal outer frame 4 (seeing other frame of broken lines among Fig. 4) part, makes lamellar body 22,23 and metal outer frame 4 integral body of form in theory.Antenna body radiation fin 4 by antenna body excitation sheet 3, produces first resonance of antenna, frequency range 824MHz-960MHz for having the U type of conduit 21; Antenna body radiation fin 2 again and have slit 22 between the metal outer frame 4 by antenna body excitation sheet 3, produces second resonance of antenna, frequency range 1710MHz-2170MHz, thus constitute 3G multifrequency integral antenna.
The present invention utilizes the basic principle of slot antenna, reduces the influence of antenna metal ground on every side to antenna, and in conjunction with the antenna coupled wave theory, an ingenious part of utilizing metal outer frame to make it to constitute antenna produces the another one slit.Antenna is originally as coupling slot crack antenna form, adopt double-layer printing circuit board, penetrate sheet by a single width and produce signal excitation, it is low-frequency resonant that the slit of antenna own produces first resonance, and it is high-frequency resonant that the slit between antenna and the metal outer frame mainly produces second resonance.And utilize the peripheral width of cloth of antenna slots to penetrate sheet, make antenna and metal outer frame become as a whole in theory, the unfavorable factor in space is converted into favorable factor to antenna with the metal outer frame coupling.
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 claim 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.
