Abstract
The utility model provides a kind of mobile terminal antenna of all-metal bonnet, including：Metal back cover and the ceramic frame on the outside of metal back cover, the ceramic frame madial wall are provided with antenna, and the metal back cover inner surface setting has the first tuner and second tune device being connected with antenna.The utility model utilizes the unique property of ceramic frame, and antenna is arranged on ceramic frame, and it effectively reduces the electrical length of antenna, and the space for taking antenna is smaller, utilization rate is higher；And the utility model all-metal bonnet does not have to crack, therefore mobile terminal is more attractive in appearance and has texture.
Description
Technical field
The utility model is related to antenna, and in particular to be a kind of mobile terminal antenna of all-metal bonnet.
Background technology
There is the intelligent mobile phone terminal of metal back cover at present, because of its exclusive sense of touch, and increasingly by the green grass or young crops of consumer
Look at.Correspondingly, the design solution of various metal class antennas is also emerged in an endless stream, and wherein bottom slit type ID, metal back cover are opened
Seam, side frame ' U ' type gap, become the main way of metallic mobile phone ID designs.At the same time, metal back cover gap of not cracking is set
Counting antenna turns into the design challenges of current antenna.
Utility model content
Therefore, the purpose of this utility model is to provide the mobile terminal antenna that a kind of metal back cover does not crack gap.
The purpose of this utility model is achieved through the following technical solutions.
A kind of mobile terminal antenna of all-metal bonnet, including：Metal back cover and the ceramic side on the outside of metal back cover
Frame, the ceramic frame madial wall are provided with antenna, and the metal back cover inner surface setting has the first tuning being connected with antenna
Device and second tune device.
Preferably, first tuner is the match circuit of matching antenna, and it is used for corresponding of the impedance of tuned antenna
It is fitted on 50 Ω.
Preferably, the second tune device is the antenna tuning switch for tuned antenna bandwidth.
Preferably, the thickness of the ceramic frame is 5~7mm, and its dielectric constant is 33.4, dielectric loss 0.0223.
Preferably, the metal back cover size is 145mm*70mm*7mm.
Compared with prior art, beneficial effect is the utility model：The shifting of all-metal bonnet provided by the utility model
Dynamic terminal antenna utilizes the unique property of ceramic frame, antenna is arranged on ceramic frame, it effectively reduces the electricity of antenna
Length, make that antenna takes space is smaller, utilization rate is higher；And the utility model all-metal bonnet does not have to crack, therefore move
Dynamic terminal is more attractive in appearance texture.
Brief description of the drawings
Fig. 1 is the front view of the mobile terminal antenna of the utility model all-metal bonnet；
Fig. 2 is the stereogram of the mobile terminal antenna of the utility model all-metal bonnet.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
For current metal back cover mobile terminal for ensure antenna performance, and need cracked in metal back cover bottom or
The mode in side frame ' U ' type gap, is easily destroyed the problem of mobile phone is attractive in appearance, and the present embodiment proposes a kind of all-metal bonnet and do not opened
Seam, frame uses ceramic material, by design of the Antenna Design on ceramic dielectric.
Refer to shown in Fig. 1, Fig. 2, Fig. 1 is the front view of the mobile terminal antenna of the utility model all-metal bonnet；Fig. 2
For the stereogram of the mobile terminal antenna of the utility model all-metal bonnet.
The mobile terminal antenna of all-metal bonnet described in the utility model include all-metal without slit metal bonnet A and
Ceramic frame B, ceramic frame B are compassingly set at metal back cover A side.
Wherein metal back cover size is 145mm*70mm*7mm；The thickness of ceramic frame is 5~7mm, and its dielectric constant is
33.4, dielectric loss 0.0223.
Antenna is provided with ceramic frame B, metal back cover A inner surface setting has the first tuner being connected with antenna
C and second tune device D.
Wherein the first tuner C is the match circuit of matching antenna, and effect is the impedance of tuned antenna, makes its more preferable
It is fitted on 50 Ω.
Second tune device D switchs for antenna tuning, and effect is tuned antenna bandwidth, using the multy-way switching of switch, realizes
The expansion of the beamwidth of antenna.
In summary, the utility model causes all-metal bonnet to compare traditional solution party using the unique property of ceramic dielectric
Case (crack or slit), without cracking, therefore mobile terminal is more attractive in appearance texture.In addition, the dielectric constant of ceramic dielectric
Height, by Antenna Design above ceramic dielectric, it can reduce the electrical length of antenna, relative to common material, the utility model
Antenna take space is small, utilization rate is high；And the utility model bulk metal bonnet combination ceramic frame can make mobile phone overall
Become more frivolous.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
