Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, right
The present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, and
It is not used in the restriction present invention.
For little due to the gap between antenna in existing mimo antenna, coupling is strong, and the needs isolation existed is to eliminate
The problem of coupling between antenna, this application provides the parasitic low section high-isolation mimo antenna of a kind of coupling.
The present embodiment, in the case of guaranteeing LTE mimo antenna performance, can improve between antenna in limited space
Isolation, so that it is guaranteed that the normal work of mimo antenna system, and uses PCB antenna design simultaneously, has low excellent of section
Point, it is possible to be easy to the processing of product and the assembling of finished product.
As it is shown in figure 1,1-1 is the floor map of high-isolation mimo antenna of the present invention in Fig. 1.Of the present invention
Mimo antenna includes pcb board, pcb board is provided with PCB line areas 10 and clearance zone 20, clearance zone 20 is provided with first antenna
40 and second antenna 50, it is provided with a divider wall 30 between described first antenna 40 and the second antenna 50.
In the present embodiment, pcb board is rectangle, and the PCB line areas 10 that it is correspondingly formed is also rectangle, in PCB line areas 10
Outer side edges be clearance zone 20, the left side clearance zone of line areas is provided with first antenna 40；The upper side edge clearance zone of line areas
It is provided with the second antenna 50.
It should be noted that the base material of pcb board is FR4 plate, dielectric constant is 4.3.
In Fig. 1,1-2 is the schematic perspective view of high-isolation mimo antenna of the present invention.In the present embodiment, first antenna 40 includes
First antenna coupling unit 41 and first antenna radiating element 42, first antenna radiating element 42 is positioned at first antenna coupling unit
Between 41 and PCB line areas 10, and one end of first antenna coupling unit 41 is connected with the PCB ground in PCB line areas 10.PCB
A first antenna distributing point 11 corresponding with first antenna radiating element 42 position it is provided with on line areas 10.Second antenna 50 wraps

Close between unit 51 and PCB line areas 10, and one end of the second antenna coupling unit 51 is with the PCB ground in PCB line areas 10 even
Connect.Second antenna feed point 12 corresponding with the second antenna radiation unit 52 position it is additionally provided with on PCB line areas 10.
As a example by PCB line areas 10 is as rectangle, it is two adjacent that first antenna 40 and the second antenna 50 lay respectively at this rectangle
Bian Shang, divider wall 30 is then positioned at the intersection of two adjacent edges.Divider wall 30 in the present embodiment is waveform cabling, and its two ends are divided
Not being connected to PCB line areas 1, centre is blank clearance zone.
In certain embodiments, divider wall 30 can be square wave cabling, sinusoidal wave cabling, snakelike cabling or triangular wave cabling
In any one.
It addition, the present embodiment is only described with PCB line areas 10 for rectangle, and it is other for PCB line areas 10
Shape, such as circular or oval and other shapes, it would however also be possible to employ said structure and mode, the present embodiment correspondence first
The shape of antenna, the second antenna and divider wall all has a corresponding change, but divider wall is respectively positioned on first antenna and second day
Between line.
As in figure 2 it is shown, the impedance operator figure that Fig. 2 is band divider wall of the present invention.It can be seen that low-frequency resonant compares
The preferable frequency range covered beyond the 700MHz that LTE uses except America, 790MHz-960MHz, two isolation between antennaes are also
Within getting at-15dB, high-frequency resistance can cover 1450MHz-2690MHz, within isolation can arrive-16dB,
Fig. 5 is the impedance operator schematic diagram after the present invention removes divider wall.In terms of data, isolation deteriorates clearly,
Being only-7dB, the self-impedance for low frequency that adds of divider wall affects little, but isolation has the improvement of 8dB, has reached non-
The most preferably the isolation contrast of state high frequency sees that without divider wall be-17dB, and the impact of divider wall is little, does not play improvement and makees
With.
Fig. 3-1 is the low frequency Surface current distribution figure that the present invention is formed in first antenna；Fig. 3-2 is that the present invention was at second day
The low frequency Surface current distribution figure that line is formed.Fig. 6-1 removes, for the present invention, the low frequency surface that the first antenna after divider wall is formed
Current distributing figure；Fig. 6-2 removes, for the present invention, the low frequency Surface current distribution figure that the second antenna after divider wall is formed.From whole
CURRENT DISTRIBUTION sees arm low frequency mainboard being defined to 1/4 wavelength, and antenna end also form 1/4 wavelength arm, constitutes asymmetric
Element antenna, right side and upper side wall in main board region add divider wall structure, a length of 1/2 wavelength, form back the LOOP on ground
Structure, electric current can be seen that and defines 2 obvious envelope current convergence regions on divider wall, which increase 2 skies
The current path of line serves the effect strengthening isolation.
Fig. 4-1 is the band divider wall first antenna of the present invention Surface current distribution figure at high frequency treatment；Fig. 4-2 is band of the present invention
Divider wall the second antenna is at the Surface current distribution figure of high frequency treatment；Fig. 7-1 be the present invention without divider wall first antenna at high frequency
The Surface current distribution figure at place；Fig. 7-2 is the present invention without divider wall the second antenna at the Surface current distribution figure of high frequency treatment.Right
Presenting 1/2 wavelength in high frequency, antenna radiator and coupling unit, mainboard is 1/2 wavelength, and divider wall part is 1 wavelength
Structure, from current cut-off, the change to electric current is not it is obvious that so in HFS divider wall structure for high frequency shadow
Ring little.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Any amendment, equivalent and the improvement etc. made within god and principle, should be included within the scope of the present invention.
