Description
Technical field
The present invention relates to antenna for mobile phone field, more particularly to a kind of slot antenna and metal-back mobile phone.
Background technology
Current mobile phone is substantially plastic casing, and the appearance mobile phone screen of smart mobile phone is increasing, and mobile phone thickness also more comes
More and more thinner, incident mobile phone mechanical strength is not enough, causes mobile phone to damage, mobile phone can be greatly improved using metal-back
Mechanical strength, can also further reduce mobile phone thickness, but metal-back antenna for mobile phone can not be realized due to the shielding of metal-back,
In order to improve giant-screen mobile phone mechanical strength, industry can only use handset front case metal material, rear shell or plastic material, but
Handset front case is most of shared by mobile phone screen, mobile phone intensity or deficiency.
Mobile phone with metal shell, if using traditional slot antenna, gap is a uniform rectilinear, and size is the list of half-wavelength
Frequency antenna, is generally used for base station, and antenna size is very big, so cannot be used for mobile phone.
The content of the invention
It is an object of the invention to provide a kind of slot antenna, significantly reduce antenna size, be adapted to different phone housings
With the use demand of frequency range.
Another object of the present invention is to provide a kind of metal-back mobile phone, hand set machine shell can be made all to use metal system
Make, strengthen the mechanical strength of phone housing.
The purpose of the present invention is achieved through the following technical solutions.
A kind of slot antenna, the gap of the slot antenna is the curved gap of m bars, m >=1；Between the gap
Provided with feed point, radiofrequency signal is radiate from the feed point feed-in, electromagnetic wave along gap both sides.
Wherein, nonmetallic materials are filled with the gap.
Wherein, the width in the gap is heterogeneous.
Wherein, the gap is specially " one ", " H ", " X ", " L ", " U ", " S " or " 8 " shape；In " one " the shape gap
Between thin, two hem widths.
A kind of metal-back mobile phone, the handset shell is metal shell；The curved seam of m bars is offered on the metal shell
Gap, m >=1；Feed point is provided between the gap, radiofrequency signal is radiated from the feed point feed-in, electromagnetic wave along gap both sides
Go out.
Wherein, nonmetallic materials are filled with the gap.
Wherein, the width in the gap is heterogeneous.
Wherein, the gap is specially " one ", " H ", " X ", " L ", " U ", " S " or " 8 " shape；In " one " the shape gap
Between thin, two hem widths.
Compared with prior art, the embodiment of the present invention has the advantages that：
1）The embodiment of the present invention and traditional slot antenna difference are：Traditional slot antenna gap is one uniform straight
Line, gap length cannot be used for greatly mobile phone very much close to the half-wavelength of operating frequency of antenna, single-band antenna, such antenna size.And
The present invention is a kind of slot antenna of evolution, and seam shape is determined based on slot edge size of current, the larger position of electric current
Gap is wider, and electric current is smaller, and position gap is narrower, and the antenna size designed using the present invention is less than the half-wave of operating frequency of antenna
It is long（Traditional slot antenna gap length is equal to the half-wavelength of working frequency）.The antenna slots of the present invention to be uniform or non-homogeneous,
Shape can be one or several non-directional gap, can be designed to multifrequency antenna, greatly reduce the size of antenna, can
To be convenient to use on mobile phone.
2）In the embodiment of the present invention, hand set machine shell all can be made using metal, further reduce mobile phone thickness, be increased
The strong mechanical strength of phone housing.

Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
The present invention core concept be：The problem of existing for current giant-screen mobile phone intensity is stitched there is provided one kind by tradition
Gap antenna develops the slot antenna of coming, and the application of the slot antenna can be such that hand set machine shell is all made using metal.Realization side
Formula is to output one or several gaps in mobile phone metal-back, and gap is by there is mobile phone one side to reserve appropriate space, and radiofrequency signal is from seam
Feed-in between gap, electromagnetic wave is radiate along gap both sides.
In the present embodiment, slot antenna has the characteristics that：
1. curve gap is developed into the gap of slot antenna by a uniform rectilinear gap；
2. high dielectric constant Filled Dielectrics gap is used；
3. non-homogeneous by uniformly developing into, the location of C electric current in Fig. 1 gaps is smaller, narrower, and D positions electric current is larger, wider,
Antenna size diminishes；
4. the center section electric current of Fig. 3 rectilinear slots is smaller narrower, the larger wider shape of two head currents, can be larger
Reduce antenna length.
For different phone housing features and frequency range demand, slot antenna can be designed to " Z ", " H ", " X ", " L ", " U "
The form such as " S " and " 8 ".The form of inventive antenna is more, does not enumerate herein, and all principle identicals belong to the guarantor of the present invention
In the range of shield.
Z-shaped slot antenna content is described further below in conjunction with accompanying drawing 1 and accompanying drawing 2.
Fig. 1 is the sectional drawing of metal-back mobile phone shell antenna part（Outside side）, A is housing, and B is outputed on housing A
Gap, gap can be filled with nonmetallic materials, be Z-shaped gap in figure, can also turn into other shapes of non-homogeneous gap, seam
Gap filler is nonmetallic materials.The frequency of the longer antenna in gap is lower, and the bandwidth of the bigger antenna of width in gap is wider, gap
Packing material dielectric constant is lower, and the frequency of antenna is higher.In Fig. 1, the location of C electric current in gap is smaller, narrower, D positions electric current
It is larger, wider.
Fig. 2 is Fig. 1 reverse side figure（The inside side）, this side can see that two feed points of antenna, and the two feed points are
For feed-in radiofrequency signal, can be balance feed-in or feed point is grounded, signal from another feed point feed-in,
Using non-equilibrium feed-in.The position of regulation load point can change the input impedance of antenna.Casing internal gap is nearby, it is necessary to stay
There is certain space (not indicated in figure), it is impossible to be close to interior of mobile phone component.The frequency bandwidth of space size and shape and antenna
It is relevant.The property of the bigger antenna in space is bigger to bandwidth, and frequency is lower.
Fig. 3 is the schematic diagram of " one " shape slot antenna, the slot antenna of this form and the notable area of traditional slot antenna
It is not, gap of the invention is middle thin two hem width（Traditional slot antenna is uniform）, such structure greatly reduces
The length in gap.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modifications, equivalent substitutions and improvements made within refreshing and principle etc., should be included in the scope of the protection.
