Embodiment one
The embodiment of the present invention provides a kind of mobile phone metal shell 10, as it is shown on figure 3, include antenna feed point F,
Described mobile phone metal shell 10 includes that first limit 101 of described antenna feed point F is provided with the first groove 1011,
The length direction of described first groove 1011 is perpendicular to described first limit 101, and described first groove 1011 has out
Mouth 1011a and the first cecum 1011b, described opening 1011a are positioned at the described 1st, described first cecum
1011b extends to the inside of described mobile phone metal shell 10.
Owing to ultra thin handset and large-screen mobile phone are pursued by user, the thickness of existing mobile phone is constantly reducing,
Screen is constantly increasing so that screen accounting is constantly improving, this results in mobile phone the height of antenna and
Space is constantly reducing, and height and the deficiency in space, greatly have impact on the sensitivity of antenna, resist and do
The performance such as disturbing, mobile phone uses mobile phone metal shell easily to produce electrostatic screen simultaneously, have impact on antenna further
Performance, cause the design of antenna to run into bottleneck, design result is difficult to meet user's request.Wherein, evaluate
The important indicator of antenna performance is antenna efficiency, and described antenna efficiency is that the power that aerial radiation is gone out (i.e. has
The power of effect ground converted electromagnetic wave part) and be input to the ratio of active power of antenna, i.e. antenna efficiency is one
The individual perseverance number less than 1, represents by Eff% in actual application, antenna efficiency the highest explanation antenna performance is the best.
In order to improve antenna efficiency, on the one hand need to break the electrostatic screen that mobile phone metal shell produces, on the other hand
Need to improve the CURRENT DISTRIBUTION of antenna, therefore can arrange near the antenna feed point F of mobile phone metal shell
First groove 1011, by the electrostatic on the first that is bootable mobile phone metal shell of groove 1011, improves sky simultaneously
The CURRENT DISTRIBUTION of line, improves antenna efficiency.
Example, described antenna feed point F is normally at the edge of mobile phone metal shell, with reference to Fig. 3 institute
Showing, antenna feed point F is positioned on the first limit 101 of mobile phone metal shell 10, due to antenna feed point F
It is connected with antenna, therefore can change the electricity of antenna by changing the CURRENT DISTRIBUTION near antenna feed point F
Flow distribution, therefore can arrange the first groove 1011 on the first limit 101.The length of described first groove 1011
Direction is with the first limit 101 in vertical state, it is simple to the importing of electric current i.e. discharges.Described first groove 1011 has
Opening 1011a, the part that the i.e. first groove 1011 overlaps with the first limit 101 is breaking joint, is not closed state,
It is easy to electric current flow into.The other end of described first groove 1011 is the first cecum 1011b, and the first groove 1011 is described
Extend only to the inside of mobile phone metal shell 10, do not run through the two ends up and down of mobile phone metal shell 10,
I.e. do not have and form opening on the second limit 102 relative with described first limit 101, be so easy to electric current
Release.Wherein the shape of the first groove 1011 can be rectangle, square, or irregular figure, this
This is not limited by bright embodiment, it is preferred that the first groove 1011 is from opening 1011a to first cecum 1011b
Width consistent, it is simple to the uniform release of electric current.
According to simulation result, it is known that the first groove 1011 serves obvious raising effect to antenna efficiency, when
One groove 1011 is when the width of opening 1011a to first cecum 1011b is consistent, to the first groove 1011 width
The simulation result of W is as shown in Figure 4.Fig. 4 is the change of the width W according to the first groove 1011, and antenna is imitated
The change curve chart of rate Eff%.As shown in Figure 4, when width W is more than 0.5 millimeter (mm), antenna
Efficiency has been obtained for improving；Along with the increase of width, antenna efficiency persistently increases, until width W arrives
2mm, antenna efficiency is significantly improved；When width W is more than 2mm, what antenna efficiency increased becomes
Gesture tends to mild, but is still slowly improving.Therefore actual application can select according to concrete condition
Suitably width W, but the maximum of width W not can exceed that the width of mobile phone metal shell 10, the widest
Degree W is more than or equal to 0.5mm, less than the width of mobile phone metal shell 10.It is also preferred that the left width can be selected
Degree W is 2mm, because when width W is 2mm, and the width of the first groove 1011 and mobile phone metal shell
The width of 10 is compared less, does not affect the aesthetic property of mobile phone, the most as shown in Figure 4, when width W is 2mm
Time, antenna efficiency is significantly improved, and therefore, takes into account attractive in appearance and practicality, and width W is that 2mm is
Preferably select.
Concrete, to the simulation result of the first groove 1011 length H as it is shown in figure 5, Fig. 5 is according to first
The change of length H of groove 1011, the change curve chart of antenna efficiency Eff%.As shown in Figure 5, when first
When groove 1011 length H is more than 10mm, antenna efficiency has been obtained for improving；Along with the increase of length H,
Antenna efficiency persistently increases, until length H to 40mm, antenna efficiency is significantly improved；Work as length
When H is more than 40mm, antenna efficiency starts slowly to decline, but the speed declined is slower.Therefore reality should
Suitable length H can be selected according to concrete condition, but the maximum of length H not can exceed that hands in
The length of machine metal shell 10, i.e. length H are more than or equal to 10mm, less than described first limit to the second limit
Distance, described second limit 102 is relative with described first limit 101.Optionally, can select
Length H is 40mm, because when length H is 40mm, and the length of the first groove 1011 and mobile phone metal
The length of shell 10 is compared less, does not affect the aesthetic property of mobile phone, the most as shown in Figure 5, when length H
During for 40mm, antenna efficiency is significantly improved, and therefore, takes into account attractive in appearance and practicality, and length H is
40mm is preferably to select.In actual application, the length according to mobile phone can also be to the length of the first groove 1011
Degree carries out trace adjustment, and adjustment amount is that (40 ± 2) mm is for more excellent, because length H is at (40 ± 2) mm
In the range of time, it is possible to the most significantly embody the raising to antenna efficiency of first groove 1011, it is ensured that the first groove
The improvement effect of the CURRENT DISTRIBUTION of 1011 pairs of antennas, and then improve antenna efficiency.
Embodiments provide a kind of mobile phone metal shell, including antenna feed point, described mobile phone metal
Shell includes that the first limit of described antenna feed point is provided with the first groove, and the length direction of described first groove is vertical
In described first limit, described first groove has opening and the first cecum, and described opening is positioned at described first limit,
Described first cecum extends to the inside of described mobile phone metal shell.Compared to prior art, due at mobile phone
First groove with opening it is provided with so that electrostatic can be along the first groove near the antenna feed point of metal shell
