Abstract
The invention discloses an antenna structure capable of flexibly adjusting the antenna use frequency. The antenna structure comprises an all-metal rear cover, a PCB board, a metal sheet and a metal elastic sheet, wherein the all-metal rear cover is slit to form an upper end cover and a lower end cover, a feeding point and a first grounding point are arranged on the PCB board, the PCB board is connected with the upper end cover through the feeding point and the first grounding point, the metal sheet is arranged between the PCB board and the upper end cover and is connected with the PCB board, one end of the metal elastic sheet is in shaft connection with the first grounding point, and the other end is in sliding contact with the lower end cover, and a second ground point is arranged on the lower end cover at a position sliding contact with the other end of the metal elastic sheet. The antenna structure can flexibly control the antenna debugging of each frequency band required for communication, and can adjust in the antenna frequency range which is difficult to be achieved by a single metal bottom rear cover back cover. In some models, the antenna structure provides no antenna tuning switch to reduce production cost.
Description
Technical field
The present invention relates to wireless communication technique field is and in particular to a kind of sky knot that antenna usage frequency is adjusted flexibly
Structure.
Background technology
For 4G the whole network lead to all-metal bonnet smart mobile phone, be directed to the antenna technology of this type at present it is simply that
With the segmentation metal that cracks come designing antenna, the antenna of design, in the metal top separating or bottom, is made using metal itself
Receive and transmission signal for antenna radiator.
Crack segmentation metal debugging antenna, be often difficult to control the metal separating so as to effective operating frequency just
It is difficult to ensure high-quality communication effect in the characteristic frequency that communication needs.And because whole machine ID can not become easily, crack
Position is difficult to adjust, the more bad control of antenna.
Content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, provides a kind of antenna that antenna usage frequency is adjusted flexibly
Structure.
Technical scheme is as follows：
A kind of antenna structure that antenna usage frequency is adjusted flexibly, including：All-metal bonnet, pcb board, foil,
Metal clips, all-metal bonnet cracks to split and 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 with upper end cover with the first earth point through distributing point；Foil is between pcb board and upper end cover and and pcb board
Connect；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
It is provided with the second earth point at 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 foil is 0.8mm apart from the distance of upper end cover.
It is preferred that foil is a size of：Long 5～20mm, wide 3～7mm, high 0.2mm.
The present invention can flexible communication control each frequency range required antenna adjustment, be difficult in monometallic bottom bonnet
Antenna frequencies scope, the present invention can adjust.On part type, antenna tuning switch can be cancelled by this invention, reduce
Production cost.
Brief description
Fig. 1 is the structural representation of the present invention；
Fig. 2 is antenna adjustment pi-network figure on pcb board in the present invention.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, invention is described in detail.
With reference to shown in Fig. 1, the antenna structure of the present invention includes：Crack the bottom all-metal bonnet 1 of segmentation, pcb board 2, gold
Belong to thin slice 3, metal clips 4.
With all-metal bonnet 1 metal as antenna body, a distributing point 21 and a ground connection are designed in pcb board 2 about two ends
Point 22, between two points, distance is in more than 30mm；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 concurrently accessed upper end cover 11.By debugging antenna-matching circuit, part communication can be met
Band requirement, its debugging circuit is shown in that Fig. 2, Fig. 2 show the antenna adjustment pi-network figure above a pcb board 2, above circuit
The position of reserved 4 patch couplings, the coupling of tri- positions of E1/E2/E4, E3 position is not used and is not pasted coupling, and as E1 is electricity
Sense 4.3nH, E2 are electric capacity 3.6pF, and E4 is zero ohm (being equivalent to conducting state), and E3 is off.
Apart from upper end cover 11 0.8mm height and position, design the foil 3 of a piece of adjustable size, by with bottom
Couple between upper end cover 11, change antenna resonance.By being sized：Long 5～20mm, wide 3～7mm, high 0.2mm, permissible
Monometallic bonnet unapproachable frequency resonance is controlled to be used for meeting communication frequency band demand, the method communicates frequency to improving altofrequency
Section has remarkable result.
Bottom upper end cover 11 earth point position increase a metal clips 4, the rotatable constant bearing again of metal clips 4,
Metal clips 4 can contact on the upper end cover of bottom it is also possible to touch above bottom bottom end cover 12, in bottom bottom end cover 12
Connect slip synapsis with metal clips 4 and be provided with the second earth point 5.By adjusting metal clips 4 orientation, can be low with effective control antenna
Frequency communication frequency range uses.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any those familiar with the art in the technical scope of present disclosure, technology according to the present invention scheme and its
Inventive concept equivalent or change in addition, all should be included within the scope of the present invention.
