Embodiment
Embodiment：
It refer to Fig. 1, the present embodiment is the antenna system based on all-metal back-cover smart mobile phone, it includes metal back cover 1, integrated
Pcb board 2, upper end-face edge and the lower edge of metal back cover 1 are provided with C-shaped gap 3, and the top of metal back cover 1 is stitched
The part that gap 3 is separated forms c-type radiating principal 4, and the antenna system also includes being arranged on integrated pcb board 2 and and c-type
The connector of connection c-type radiating principal 4 and integrated pcb board 2 is provided with some coupling units that radiating principal 4 is coupled, gap 3
5。
Some metal material modules are provided with integrated pcb board 2（Do not indicated in figure）, after the metal material module includes
Put camera 6, front camera 7, earpiece screen decoration 8 and the radiation patch fitted with an angular zone of rear camera 6
Piece 9.It is radiation for the first coupling part of radiation medium, with rear camera 6 that the coupling unit, which is included with the radiation patch 9,
Second coupling part of medium, with front camera 7 for the 3rd coupling part of radiation medium and with earpiece screen decoration 8 it is spoke
Penetrate the 4th coupling part of medium.Radiation patch 9 is arranged on the angular zone position of integrated pcb board 2, and is provided with positioned at rearmounted shooting
The extension of first 6 top（Do not indicated in figure）.
Fig. 1 is refer to, gap 3 is in the c-type structure after 90 degree of rotate counterclockwise, as can be seen from Figure 1 c-type radiating principal 4
It is approximately a c-type, the width in gap 3 is smaller, and antenna performance will be deteriorated, but the overall appearance of communication terminal can be more beautiful
See, general gap can be arranged on the width in gap 3 in 2mm, the present embodiment less than 1mm in the prior art.
The switch element 10 of connection c-type radiating principal 4 and integrated pcb board 2 is additionally provided with gap 3.
The c-type radiating principal 4 that the top of gap 3 is formed in metal back cover 1 is used as the metal radiation main body of antenna, wherein c-type
The left and right ends of radiating principal 4 form primary antenna radiating principal；The metal material mould of large area in integrated pcb board 2
Block just form it is main " ", metal radiation main body and the master " " between be provided with tie point at two, i.e. connector 5 and switch
Unit 10.
Connector 5 connects c-type radiating principal 4 with the coupling unit formed on integrated pcb board 2 by metal material
The distance of one, distributing point of the connector 5 as antenna energy, connector 5 and the lateral edges of metal back cover 1 one is 14 ~ 16mm, most
It is excellent for 15mm, this distance for metal back cover 1 from a left side to connector 5 the corresponding resonance band of length, the benefit so set
It can be camera with the relative distance of feed in 4-5mm or so to be, now, rear camera 6 is become for whole antenna
Second coupling unit, and the radiation to electromagnetic wave is participated in, the coupling of this section can strengthen whole antenna system in high band
（2170-2690MHz）Radiation characteristic, energy is fed into c-type radiating principal 4, c-type by electromagnetic wave first by the distributing point
Electromagnetic wave energy is radiated from left to right by the distributing point on radiating principal 4, in electromagnetic energy communication process, by with
Coupling between two coupling parts, can reach the purpose of enhancing high band radiation effect.
Meanwhile, because the width in the gap 3 in this programme is less than 1mm, the radiation of antenna is had a strong impact on, in order to improve antenna
The deterioration brought because gap is too narrow, introduce the radiation patch 9 in distributing point part, and this metal minor matters of radiation patch 9 are drawn
The characteristic impedance at the feed of antenna can be changed by entering, it is ensured that the S11 of antenna（That is return loss）It is functional.Pass through connector
5 by the master of c-type radiating principal 4 and bottom " " connect, can help to match what is be coupled to by first coupling unit
Frequency electromagnetic waves and first coupling unit together, can realize good HFS S11 and radiation characteristic.
Front camera is introduced to the 3rd coupling part as radiation medium, the double shootings of the optimal use of front camera
Head, by the way that to the abundant contact between this camera and metal back cover 1, the electromagenetic wave radiation that can be allowed in main radiator arrives this
No longer as farther place radiation after place, so, the metal in the right corner of operative tip falls on mobile phone is not involved in radiation, such one
Come, when we hold or during head contact edge, the radiation characteristic of this antenna system is not in larger deterioration, very well solution
The problem that the head hand of antenna for mobile phone of having determined retracts.
Earpiece screen decoration is metal part, and the part is also cleverly used the radiation for participating in antenna.By receiver
Net decoration introduces the 4th coupling part as radiation medium, and this section of coupling can strengthen radiation effect of the antenna in Mid Frequency
（1710-2170MHZ）.
Switch element 10 is a kind of variable power switch of consecutive variations, different from general single pole multiple throw, this switch
Reactance value can consecutive variations, so, the radiating bands of antenna just can be moved continuously, can preferably cover full range
The demand of section.The distance of switch element 10 and connector 5 is 18-22mm, optimal for 20mm.
When switch element 10 is in different reactance values, frequency displacement occurs in the S11 performances of antenna system, as shown in Figure 2.
From figure 2 it can be seen that when switch element 10 is in tri- kinds of typicalnesses of 0.75pf, 1.4pf, 3.1pf, the present embodiment
Antenna system can cover the electromagnetic wave of 0.72-1.1GHz, 1.6GHZ-2.8GHZ frequency range, fully meet the demand of all frequency bands antenna,
On this basis, when switch element 10 is in other values, the performance of antenna can be optimized accordingly.
The beneficial effect of antenna system of the present embodiment based on all-metal back-cover smart mobile phone is：In all-metal back-cover
The excellent antenna system of radiance is realized under structure, while the integrality of metal back cover is improved, antenna is improved
The radiation characteristic of each frequency range.Specifically,
1）Employ in the middle part of the terminal appearance form that a kind of upper and lower part of all-metal back-cover is all c-type, such a metal back cover
Region is bigger, visually can be more complete；
2）Segmentation plastic parts in metal back cover is arc, compares shell terminal after traditional three-stage metal（Splitting plastic parts is
Linear pattern）With more aesthetic property and affinity；
3）Only realize that full frequency band is radiated with the c-type radiating principal 4 on top；
4）Separate gap width in below 1mm, improve the integrality of aesthetics and metal back cover；
5）Compared to prior art, the presence of front camera and rear camera is that the radiation characteristic that can make antenna is deteriorated, but is fitted in this programme
When choose antenna feed and camera relative position, infringement of the camera to antenna radiation efficiency can not only be eliminated, also
The radiation effect of antenna can be strengthened using the metal Coupling effect of camera；
6）Coupled everywhere using front camera and rear camera and earpiece screen decorative frame and coupling minor matters, during both having met mobile phone each metal
Rationally visit, improves the radiation characteristic of each frequency range of antenna again；
7）Because the empty regions of this c-type metal antenna are small, track lengths are short, and its debugging difficulty is big, and this programme utilizes metal
