Specific implementation mode
It is described in further detail below by specific embodiment and in conjunction with attached drawing to the present invention.
As shown in Figure 1, an embodiment of the present invention provides a kind of antenna system, including rear shell 20 and the side frame that is oppositely arranged
11, side frame 11 is metal edge frame, and the first breaking joint 111 and the second breaking joint 112 are provided on each side frame 11.Rear shell 20 includes phase
To two lateral edges, each lateral edges are disposed with the first empty regions 21, the second empty regions 22, third empty regions 23
With the 4th empty regions 24, the first empty regions 21, the second empty regions 22, third empty regions 23 and the 4th empty regions 24
Edge be respectively arranged with distributing point 30, i.e. distributing point 30 is set to the edge of each empty regions.Two lateral edges and two
Side frame 11 is oppositely arranged respectively, and the first empty regions 21 are connected to the first breaking joint 111, the 4th empty regions 24 and the second breaking joint
112 connections, that is to say, that rear shell 20 is set there are two the first empty regions 21, two the second empty regions, 22, two third headroom
Region 23 and two the 4th empty regions 24 keep the first empty regions 21, second net to form 8*8 array mimo systems
Empty region 22, third empty regions 23 and the 4th empty regions 24 are respectively formed 5G antennas.
The first empty regions 21, the second clearance zone is arranged close to the edge of side frame 11 in rear shell 20 in above-mentioned antenna system
Domain 22, third empty regions 23 and the 4th empty regions 24, that is, form two kinds of mimo systems, the first system includes the second headroom
Region 22 and third empty regions 23, which is closed area；Second of system includes 21 He of the first empty regions
4th empty regions 24, the empty regions are non-close structure, to make four empty regions be respectively formed 5G antennas, and are passed through
The combination of multiple empty regions can improve the transmission rate of 5G antennas, promote the noise capacity of 5G antennas, it is clear that the present invention
Multiple empty regions are arranged in the limited space of mobile terminal in the space for making full use of mobile terminal edge, to form 8*8 times
Row mimo system forms 5G antennas, adapts to the development trend of mechanics of communication；Meanwhile this antenna structure, due to being arranged in side
It is smaller to the space hold of the main screen of mobile terminal near frame 11, it is thus possible to enough meet the development need of full frame mobile terminal
It asks.
The working frequency range of above-mentioned 5G antennas is 3300MHZ~3600MHZ and 4800MHZ~5000MHZ, the two frequency range energy
Enough cover the newest frequency range of CONTINENTAL AREA OF CHINA 5G.
Usually, mobile terminal includes frame 10, and the material of frame 10 and rear shell 20 is metal material, to promote movement
The texture of terminal.Frame 10 along rear shell 20 peripheral ring around setting, when mobile terminal is rectangular parallelepiped structure, frame 10 is rectangular
Ring, above-mentioned side frame 11 are the part of straight-flanked ring in the longitudinal direction, and frame 10 further includes the top margin for connecting two side frames 11
Frame 12 and boundary frame area 13.Wherein, frame 10 and rear shell 20 can be separate structure, or integral structure.
For the ease of the setting of mobile terminal internal part, antenna system is generally positioned at the top margin frame 12 of mobile terminal
And/or near boundary frame area 13, therefore, the first breaking joint 111 and the second breaking joint 112 are generally disposed at the both ends of side frame 11, i.e.,
One breaking joint 111 is close to top margin frame 12, and the second breaking joint 112 is close to boundary frame area 13.
After first empty regions 21, the second empty regions 22, third empty regions 23 and the 4th empty regions 24 pass through
The edge of shell 20 is recessed inwardly to be formed.
Specifically, the first empty regions 21, the second empty regions 22, third empty regions 23 and the 4th empty regions 24 are equal
Length direction for bar-shaped zone, bar-shaped zone is consistent with the extending direction of side frame 11, by setting each empty regions to
Bar-shaped zone can improve the directionality of 5G antennas, and then promote the performance of 5G antennas.
Since the first empty regions 21, the 4th empty regions 24 are connected to the first breaking joint 111, the second breaking joint 112 respectively, because
This, the 5G antenna performances that the first system is formed are improved, and totally enclosed second empty regions 22 and third clearance zone
The 5G antennas that domain 23 is formed, in order to the 5G antenna performance phases with the first empty regions 21, the formation of the 4th empty regions 24
Match, the second empty regions 22, the length of third empty regions 23 are more than the length of the first empty regions 21 and the 4th empty regions 24
Degree, such as the second empty regions 22, the length of third empty regions 23 can be selected as the half of 5G antenna resonance wavelength, and first
Empty regions 21, a quarter that the length of the 4th empty regions 24 is 5G antenna resonance wavelength, in one embodiment, second
Empty regions 22, the length of third empty regions 23 are 32mm, and the first empty regions 21, the length of the 4th empty regions 24 are
13mm。
It is to be appreciated that being limited by size of mobile terminals, the first empty regions 21, the second empty regions 22, third are net
Empty region 23, the width of the 4th empty regions 24 are the smaller the better, and in order to promote the performance of 5G antennas, it is desirable to the width it is more big more
It is good, it is contemplated that the first empty regions 21, the 4th empty regions 24 are connected to the first breaking joint 111, the second breaking joint 112 respectively, can
The performance of 5G antennas is promoted, and the second empty regions 22, the antenna performance of third empty regions 23 are weaker, therefore, the second headroom
Region 22, third empty regions 23 width be more than the first empty regions 21 and the 4th empty regions 24 width, with as far as possible
Keep the antenna performance of each empty regions consistent, in one embodiment, the second empty regions 22, third empty regions 23 width
For 1.5mm, the first empty regions 21, the 4th empty regions 24 width be 1mm.
It should be noted that the length and width of above-mentioned each empty regions can be selected as other values.Wherein, above-mentioned length
Refer to size of the empty regions along 11 extending direction of side frame, width refers to empty regions along the ruler perpendicular to 11 extending direction of side frame
It is very little.
Using above-mentioned antenna system, return loss and the isolation figure of antenna system as shown in Fig. 2, antenna system radiation
Efficiency chart is as shown in figure 3, the dependency graph of two 5G antennas adjacent in antenna system is as shown in Figure 4.Wherein, curve L1 is the
A kind of return loss plot of system, curve L2 are the clawback loss figure of second of system, and curve L3 is close to same side frame 11
The isolation figure of two 5G antennas that is formed with third empty regions 23 of the second empty regions 22, curve L4 is close to the same side
Two 5G antennas that first empty regions 21 of frame 11 and the second empty regions 22 are formed, or close to same side frame 11
The isolation figure for two 5G antennas that third empty regions 23 and the 4th empty regions 24 are formed.Curve L5 is the first system
The radiation efficiency figure of 5G antennas, curve L6 are the radiation efficiency figure of the 5G antennas of second of system.Curve L7 is close to the same side
The dependency graph for two 5G antennas that the second empty regions 22, the third empty regions 23 of frame 11 are formed, curve L8 are close
Two 5G antennas that first empty regions 21 of same side frame 11 and the second empty regions 22 are formed, or close to same side
The dependency graph for two 5G antennas that the third empty regions 23 of frame 11 and the 4th empty regions 24 are formed.It can by Fig. 2-Fig. 4
, it is evident that the radiation efficiency for the 5G antennas that each empty regions are formed is good, the isolation and correlation of two adjacent 5G antennas
Property is also very low, meets the requirement of mimo system.
In addition, the present invention also provides a kind of mobile terminal, such as mobile phone, mobile terminal includes any one of them antenna as above
System.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
