Description
Technical field
The utility model is related to wireless communication technique field, and in particular to a kind of day that antenna frequency of use is adjusted flexibly
Cable architecture.
Background technology
Lead to the smart mobile phone of all-metal bonnet for 4G the whole networks, the antenna technology of this type is directed at present, is exactly
With the segmentation metal that cracks come designing antenna, the antenna of design is made in itself in the metal top or bottom that separate using metal
Received for antenna radiator and transmission signal.
Crack segmentation metal debugging antenna, is difficult often to control the metal separated, makes its effective working frequency just
In the specific frequency that communication needs, it is difficult to ensure high-quality communication effect.And because whole machine ID can not become easily, crack
Position is difficult to adjust, the more bad control of antenna.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art that antenna frequency of use is adjusted flexibly there is provided a kind of
Antenna structure.
The technical solution of the utility model is as follows：
A kind of antenna structure that antenna frequency of use is adjusted flexibly, including：All-metal bonnet, pcb board, sheet metal,
Metal clips, all-metal bonnet segmentation of cracking forms upper end cover and bottom end cover, and pcb board is provided with distributing point and the first earth point,
Pcb board is connected through distributing point with the first earth point with upper end cover；Sheet metal is located between pcb board and upper end cover and and pcb board
Connection；Metal clips one end is connected with the first earth point axle, the other end and bottom end cover sliding contact, bottom end cover with metal clips
The second earth point is provided with other end sliding contact.
It is preferred that distributing point and the first earth point distance are not less than 30mm.
It is preferred that sheet metal is 0.8mm apart from the distance of upper end cover.
It is preferred that sheet metal size is：Long 5~20mm, wide 3~7mm, high 0.2mm.
The utility model can flexible each frequency range needed for communication control antenna adjustment, in monometallic bottom, bonnet is difficult to do
The antenna frequencies scope arrived, the utility model can adjust.On the type of part, antenna can be cancelled by this utility model and adjusted
Humorous switch, reduces production cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is antenna adjustment pi-network figure on pcb board in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, utility model is described in detail.
Shown in reference picture 1, antenna structure of the present utility model includes：Crack the bottom all-metal bonnet 1 of segmentation, pcb board
2nd, sheet metal 3, metal clips 4.
Using the metal of all-metal bonnet 1 as antenna body, a distributing point 21 and a ground connection are designed in the left and right ends of pcb board 2
Distance is in more than 30mm between point 22, two points；All-metal bonnet 1 forms upper end cover 11 and bottom end cover by the framing bits 6 that crack
12, distributing point 21 and earth point 22 are linked into upper end cover 11 simultaneously.By debugging antenna-matching circuit, part communication can be met
Band requirement, its debug circuit is shown in above the antenna adjustment pi-network figure that Fig. 2, Fig. 2 are shown above a pcb board 2, circuit
The position of reserved 4 patches matching, the matching of tri- positions of E1/E2/E4, E3 positions are not used and do not paste matching, and as E1 is electricity
Feel 4.3nH, E2 is zero ohm (equivalent to conducting state) for electric capacity 3.6pF, E4, and E3 is off.
Apart from the 0.8mm height and positions of upper end cover 11, design the sheet metal 3 of a piece of adjustable size, by with bottom
Coupled between upper end cover 11, change antenna resonance.By being sized：Long 5~20mm, wide 3~7mm, high 0.2mm, can be with
The unapproachable frequency resonance of control monometallic bonnet is used for meeting communication frequency band demand, and the method is to improving high-frequency communication frequency
Section has remarkable result.
One metal clips 4 of the earth point position of upper end cover 11 increase in bottom, the rotatable constant bearing again of metal clips 4,
Metal clips 4 can be contacted on the upper end cover of bottom, can also be touched above bottom bottom end cover 12, the bottom end cover 12 in bottom
Slip synapsis, which is connect, with metal clips 4 is provided with the second earth point 5.By adjusting the orientation of metal clips 4, it can effectively control antenna low
Frequency communication frequency range is used.
The above, only the utility model preferably embodiment, but protection domain of the present utility model is not
This is confined to, any one skilled in the art is in the technical scope that the utility model is disclosed, according to this practicality
New technical scheme and its utility model design are subject to equivalent or change, should all cover in protection model of the present utility model
Within enclosing.
