Description
Technical field
The utility model belongs to field of communication technology more particularly to a kind of antenna.
Background technology
Industrial design, height screen accounting are increasingly focused on as the mobile terminal device of representative using notebook and tablet computer now
Become the favorite trend of consumers in general with high-definition camera.In this context, miniaturization and the maximum profit of antenna how to be realized
It is used in antenna with the space in system, the emphasis become in Antenna Design considers.
Utility model content
Of the existing technology in order to solve the problems, such as, the utility model proposes a kind of antennas.
Technical solution used by the utility model is：
A kind of antenna, be applied to notebook mobile terminal system, the notebook mobile terminal system include screen LCD and
Dorsal shield, the dorsal shield include antenna area and non-antenna area, which is characterized in that antenna includes antenna body and Camera
PCB；The antenna body and the Camera PCB are respectively positioned on the antenna area；The antenna body be located at notebook bottom
The chip module connection of seat；The antenna body is coupled with the Camera PCB non-direct contacts；The Camera PCB away from
From the antenna body 65-70mm.
Preferably, the length of the antenna body is 50-55mm.
Preferably, width≤10mm of the antenna area.
Compared with prior art, the utility model has the beneficial effects that：
The utility model has the characteristics that, compared with miniature antenna ontology, to radiate using Camera PCB auxiliary antennas, by antenna sheet
Body, to 52mm, therefore can realize overlength Cameran PCB (high-definition camera function) by original 65mm length reductions, while meet super
Wide frequency antenna design requirement.
Certainly, any products for implementing the utility model do not necessarily require achieving all the advantages described above at the same time.

In figure, 1- antenna areas；The non-antenna areas of 2-；3- screens LCD；4- antenna bodies；5-Camera PCB；6- is specific
It is grounded position.
Specific implementation mode
It is new to this practicality below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Each embodiment of type is explained in detail.
As shown in Figure 1, a kind of antenna, be applied to notebook mobile terminal system, can kettle cover LTE (4G)/3G/GPS frequency ranges,
Notebook mobile terminal system includes screen LCD3 (AB shells) and dorsal shield (A shells), and dorsal shield includes antenna area 1 (being made of plastics)
It (is made of carbon fibre material) with non-antenna area 2, wherein antenna includes antenna body 4 and Camera PCB5 (Camera PCB5
Length reaches 105mm)；Antenna body 4 and Camera PCB5 are respectively positioned on antenna area 1；Antenna body 4 be located at notebook base
Chip module connection (carrier of the antenna body 4 as receiving and transmitting signal, chip module pass through it completion signal reception and transmitting
Effect, reaches normal communication function)；Antenna body 4 is coupled with Camera PCB5 non-direct contacts；Camera PCB5 distances
(since the end of antenna body 4,65-70mm generally refers to the direction " X ", i.e. 4 length of antenna body to antenna body 65-70mm
Direction).65-70mm is quarter-wave aerial length, can use formula (300/ frequency) * 0.25*0.96=antenna lengths
(wavelength) is calculated, and advantage is exactly to expand the beamwidth of antenna.In order to meet screen ultra-narrow frame design, (Gao Ping is accounted for
Than) and high-definition camera effect (multiple cameras), the present embodiment diminution 4 volume of antenna body, 4 volume of antenna body is specially 52
× 10 × 2mm has reached the design requirement of ultra-wideband, i.e. 700- using Camera PCB5 as auxiliary antenna radiator
960MHz, 1575-2700MHz, 5150-5925MHz.
In the present embodiment, antenna body 4 is used as major radiator, connects associated component module (notebook base, keyboard end
Chip module), Camera PCB5 generate effective resonance, reach as antenna auxiliary radiator using specific ground connection position 6
The effect of bandwidth is expanded, the invention is in the volume for reducing antenna body 4 to greatest extent, and increasing Camera PCB5, (high definition is taken the photograph
As/more kinetic energy) in the case of dimensional space, reach UWB Antenna design requirement.
As shown in Fig. 2, the voltage standing wave ratio (VSWR) of the antenna and ordinary antennas of the present embodiment under notebook mode.From
From the point of view of the two comparison, in 700-900MHz band limits, there is apparent bandwidth broadning effect, even if antenna body 4 is compressed to existing
52 × 10 × 2mm, can still meet LTE (4G)/3G/GPS's (700-960,1575-2700,5150-5925MHz)
Bandwidth requirement.
As shown in figure 3, the efficiency comparative of the antenna and common form antenna of the present embodiment.Bottom has initial frequency in figure
(Start) and terminate frequency (Stop), i.e. 500MHz-3GHz.Other two curve has the corresponding Mark points, mark1 to be
717MHz, mark2 960MHz.The present embodiment is expanded under notebook mode before bandwidth
Between mark1 and mark2, the two performance difference is apparent.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
It is confined to this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should
It is subject to the protection scope in claims.
