Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing to the present invention make into
It is described in detail to one step, it is clear that described embodiments are only a part of the embodiments of the present invention, rather than whole implementation
Example.Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
All other embodiment, shall fall within the protection scope of the present invention.
Firstly the need of explanation, antenna provided by the invention is the antenna for being applied to mobile terminal, which can
Think the common mobile terminals such as mobile phone in the prior art, tablet computer.And the mobile terminal has metal-back 10, antenna
In setting, using the structure on metal-back 10 as radiating element.
With reference to shown in Fig. 1, wherein Fig. 1 shows the structure of metal-back 10, and the metal-back 10 is in setting, metal-back
Two gaps, respectively the first gap 13 and the second gap 121 are opened up on 10, wherein the first gap 13 cut metal-back 10
It is cut into first part 11 and second part 12；Second gap 121 is arranged on the side wall of second part 12 and makes second part 12
It is formed cyclic annular.And in specifically setting antenna, as shown in Fig. 2, the antenna includes two parts, feed element and radiating element,
Wherein, the radiating element of the antenna uses the second part 12 of above-mentioned metal-back 10.By foregoing description retouching to metal-back 10
It states as can be seen that the second gap 121 makes second part 12 form an annular structure when second part 12 is arranged.From
And loop antenna can be formed with feed element, to improve the performance of antenna.
And it can be seen from foregoing description when the radiating element of antenna is arranged, it is only necessary to open up two on metal-back 10
Gap, process it is fairly simple, so that processing effect can be improved, and then improve yields in specific production.
When second gap 121 is specifically arranged, as shown in fig. 1, which includes the first side wall, second side
Wall and third side wall, in specific setting, second sidewall and third side wall are arranged on the two sides of the first side wall, and the first side wall
It is connect respectively with second sidewall and third side wall, as shown in fig. 1, describes each side wall of second part 12 for convenience, it is right
The side wall of metal-back 10 is named, wherein the two side walls along 10 length direction of metal-back are long side wall, along metal-back 10
The two side walls of width direction are end side wall.The specific structure of the metal-back 10 includes a backboard and four side walls, wherein
First gap 13 is laterally cut into two parts (perpendicular to the direction of 10 length direction of metal-back) in setting, by metal-back 10,
And two long side walls of metal-back 10 are also divided into two parts, in the side wall that the second part 12 after segmentation includes, first
Side wall is an end side wall of metal-back 10, and second sidewall and third side wall are respectively to be cut off in long side wall by the first gap 13
Partial sidewall afterwards.When the second gap 121 is arranged, which be can be set on the wall of end side, by can be in Fig. 1
Find out, which only has 121 1, the second gap gap when in setting to end side wall on the wall of end side, therefore,
It is arranged with biggish space, facilitates the processing in the second gap 121.In addition, this second when forming the second gap 121
Gap 121 is a gap closed at both ends, i.e. second gap 121 makes end side wall form an annular structure, thus
So that the second part 12 can be used as cricoid radiator, when connecting with feed element, so that entire antenna forms one
Loop antenna, to improve the performance of antenna.
In addition, at specifically the second gap 121 of setting, the both ends of second seam can as a specific embodiment
Extend respectively into second sidewall and third side wall.As shown in Figure 3, the both ends in second gap 121 extend to second in Fig. 3
On side wall and third side wall, to improve the long path of electricity of antenna, and then the performance of antenna is improved.It is to be understood that
It is that in the disclosed scheme, 121 both ends of the second gap in extension, are not connected to the first gap 13, so that
The structure that second part 12 is still integrated.
Through the above scheme as can be seen that in specifically setting radiating element, since radiating element uses the second gap
121, improve the performance of antenna.And when using the structure, the current path of radiating element is separate in cyclic structure
Therefore first part 11 when using the structure, can reduce interference of the first part 11 to antenna performance, so that the
The width in one gap 13 can do narrower, width can be reduced to 0.1mm or so, compared to use in the prior art
For the gap of 1.5mm, the width in the first gap 13 being arranged on metal-back 10 can be reduced, significantly so as to improve gold
Belong to 10 aesthetics of shell.
For the feed element in the embodiment of the present invention comprising feed element includes feeding point 21 and feed line
40, and feeding point 21 is connect with feed line 40 by matching network.Wherein, feeding point 21 is arranged on circuit board 20, and should
When being connect by matching network with feed line 40, which can according to need is configured feeding point 21.One
In a specific embodiment, which includes the branch of multiple parallel connections, and is used for one of branch and feed
The selection switch that line 40 is connected to；Wherein, at least one branch road is provided with inductively or capacitively.It, can basis when specifically used
Connecting with feed line 40 by capacitor or inductance selection is needed, so as to improve the performance of antenna.
Feed line 40 therein can be prepared using conductive material relatively common in the prior art, such as the feed line 40
For feed elastic slice or FPC flexible circuit.It certainly can also be using other modes, such as LDS (laser direct forming) metal layer.?
When feed line 40 feeds radiating element, can direct feed can both be used, can also be used in different ways
Couple feed, when using couple feed, feed element and radiating element couple feed.In the present embodiment, it is coupled shown in
Feed refers to INDIRECT COUPLING, i.e., has certain gap between feed line 40 and radiating element, by way of coupling, realizes
Feed line 40 is electrically connected with radiating element.
The embodiment of the invention also provides a kind of mobile terminal, which includes the antenna for stating any one.Wherein,
The mobile terminal can be the common mobile terminals such as mobile phone, tablet computer.Wherein, which can be with reference among the above for day
The description of cable architecture, the antenna on metal-back 10 by being arranged the second gap 121, so that the radiator of antenna is at one
Annular, and loop antenna is formed with feed element, to improve the performance of antenna, and when using the structure, in metal-back 10
Different location cracks, and then improves the effect of processing, improves yields.
In a specific embodiment, the first part 11 of metal-back 10 and second part 12 are connected by conduct piece
It is logical.In specific setting, the first part 11 is with can be used as metal.And it is used between first part 11 and second part 12
Conduct piece is attached, which can be the dowel that prescinds on metal-back 10, or using conductive parts such as sheet metals
First part 11 and second part 12 are electrically connected by part.When the conduct piece is specifically arranged, which is located at above-mentioned first
In gap 13.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
Mind and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to include these modifications and variations.
