Specific embodiment
Present embodiment provides the method and way of realization that any interference in antenna array can be eliminated with self adaptation, describes in detail such as
Under：
Fig. 1 is a typical 5G base station containing Massive MIMO.101 is the antenna array of Massive MIMO,
In Fig. 1, each antenna element is microstrip antenna, and the mode of array arrangement is square formation.By adjusting the feed on each antenna element
Amplitude and phase, the Massive MIMO arrays can produce multiple wave beams as shown in 102, be respectively aligned to as indicated at 103
Each user/terminal.104 is 5G base station equipments.
Due to the finite volume of base station, the limited area of array antenna 101, it is therefore possible to use the side of super surface covering
Formula improves the performance of Massive MIMO.One two element antenna exemplary array for being coated with super surface is as shown in Figure 2.In Fig. 2
In, 202 is a microband antenna unit, and its floor is 203, and dielectric layer 205 can be filled between floor and antenna element.It is super
Cycle of resonator 208 on surface is arranged on dielectric layer 207, and is supported by support column 206.In addition, 201 is further
Improve the U-type groove of antenna match state.204 and 209 is the feed port of antenna.
By configuring the resonant frequency of resonator 208, reflection and projection coefficient, the spacing between resonator, and super table
Surface layer 207, can be with apart from the distance of antenna element 202：
1) cause that the coefficient of coup between each antenna element of multiaerial system on the super surface of covering is reduced to close to zero；I.e.
Isolation between port 204 and port 209, S21 is reduced to close to 0, or less than 20dB.
2) cause that the more original multiaerial system of gain of each antenna element in the multiaerial system on the super surface of covering is improved；
3) cause that the more original multiaerial system of coupling bandwidth of each antenna element in the multiaerial system on the super surface of covering is carried
It is high；I.e. port 204 and 209 can be in a broader frequency band, and its reflectance factor S11 is small as far as possible.Generally less than-
10dB。
4) the antenna array secondary lobe reduction on the super surface of covering is caused；
5) cause that the phase-array scanning angle on the super surface of covering broadens.
Performance improvement method proposed by the present invention is not limited to two cell arrays, Fig. 3, Fig. 4 be illustrated that super surface applications in
The example of four cell arrays.Wherein, Fig. 3 is four unit linear arrays, and Fig. 4 is four unit square formations.Except number of unit and arrangement mode
Different outer, remaining set-up mode is identical with two cell arrays of Fig. 2.
Furthermore it is possible on the basis of Fig. 2~4, one layer of super surface is further added by, as shown in figure 5,501 and 502 are respectively two
The super surface of layer, by adjustment 501, on 502, the characteristic of resonator, and dielectric layer dielectric constant, and between 501 and 502
Spacing, and 501,502 apart from antenna element 504 distance so that be coated with the multiaerial system performance on the super surface of two-layer
Improve and realized in a broader frequency range.
Fig. 6 is another way of realization of present example, and super surface 601 and 602 does not contain resonator here, is only situated between
Matter layer.By configuring the dielectric constant of 601 and 602, spacing, and apart from the distance of antenna element 604, can equally realize figure
Performance improvement as 3.
Fig. 7 and Fig. 8 is the other two way of realization on super surface in the present invention.In Fig. 7, super surface 702 is located at antenna element
701 same layer, is the feed port of antenna element with 701 common medias layer 704 and floor 703,705；And super table in fig. 8
Face 803 substituted for the floor of antenna element 801.Both forms by configure resonator characteristic and dielectric-slab dielectric it is normal
Number, can equally obtain the performance improvement of example as described in Figure 2.
Fig. 9 is the example of the antenna tunable devices 902 on super surface resonator 901.Tuner can be can power transformation
Hold, varactor, PIN diode, mems switch etc..By adjusting tunable devices, dynamic changes the humorous of the resonator
Vibration frequency, reflectance factor, transmission coefficient.
The working mechanism of super surface modification antenna performance is covered to explain, Figure 10 shows that radiation field of aerial passes through super table
There is the distribution of Poynting vector in electric field and magnetic field before and after face.1001 be radiation field of aerial by super surface before
Distribution, it can be seen that although the direction of electric field E is along the reference axis y directions shown in 1003, and the direction of magnetic field H is and x directions
There is certain angle, so, the direction of Poynting vector k will propagate (having certain angle with-x directions) so to side, if
Without super surface, the energy of the radiation of antenna element 1004 has just been coupled on unit 1005.
Add after super surface 1006, due to the anisotropy on super surface, only allow Poynting vector k along positive z-direction
Propagate, also only allow magnetic field H to be propagated parallel to super surface 1006, that is to say, that any electromagnetic wave along the x-axis direction will be pressed down
System, therefore, the electromagnetic wave for being coupled to 1005 from antenna element 1004 will be suppressed.Therefore, after the super surface of addition, antenna element
Between the coefficient of coup substantially reduce.
In addition, in comparing Figure 11 and Figure 12, containing and the Electric Field Distribution of the antenna that does not contain super surface can see, add
After super surface, more electromagnetic waves are accumulated antenna and super surface surface, rather than horizontal transmission to other antenna lists
Unit, covers the antenna gain on super surface, can be significantly higher than the antenna for being not covered with super surface.
Figure 13 is illustrated that a typical speckle parameter response for the two unit mimo antennas for not containing super surface, can see
Arrive, although the reflectance factor S11, S22 of antenna are both less than the coefficient of coup between -10dB, but Unit two, close to 10dB.Using
Super surface suppresses after horizontal transmission, and the reflectance factor S11 of antenna does not deteriorate not only, but also makes moderate progress, such as Figure 14 institutes
Show, meanwhile, the coefficient of coup between two antennas is lowered to more than -35dB.Bandwidth of operation between frequency f3-f4 is significantly greater than
Bandwidth of operation between frequency f1-f2.Indicate super surface not only reduce two antenna elements between the coefficient of coup, go back broadening
Its bandwidth of operation.
Illustrated using two unit micro-strip antenna array as specific example below, two unit micro-strips as shown in Figure 2
Aerial array, is operated in 5.8GHz, and when super surface 208 is not contained, scattering parameter such as Figure 15 that its measurement is obtained can see
Arrive, in 5.61GHz to 5.97GHz frequency ranges, reflectance factor：S11 and S22 are respectively less than -15dB, and coefficient of coup S21 close to -
8dB.Add after super surface 208, the scattering parameter of its test is as shown in figure 16, it can be seen that when containing super surface, antenna
Bandwidth of the reflectance factor less than -20dB has been substantially equal to antenna reflection coefficient when without super surface and, less than -15dB bandwidth, has said
The state and bandwidth of bright matching are all significantly improved.And coefficient of coup S21 between the Unit two when containing super surface,
It is promoted between 5.49GHz to 6GHz less than -25dB.
Except the improvement of scattering parameter, the gain containing the super antenna for showing also is significantly improved, as shown in figure 17, containing super
After surface 208, the gain of antenna element is improved and has exceeded 2 dB.
It is pointed out that in the present invention, antenna array is not limited only to two antennas, four antennas can expand to multiple days
The multiaerial system of line composition.
Described aerial array form is varied, including linear array, circle battle array, square formation, and also some are in irregular shape not
