As described above, the reconfigurable antenna (RA) with directional diagram diversity is subject in the standardization effort of 5G systems
Extensive concern.However, there are the shortcomings of gain is low, narrow bandwidth, big and complicated three-dimensional (3D) structure for existing antenna solutions.
Which has limited the performance of mimo antenna array.Mimo antenna needs RA can be sufficiently small as basic original paper.
In addition, improved for it is also proposed use direction figure RA in indoor positioning scene using received signal strength
(RSS) accuracy of alignment system.With for example based on arrival time (TOA), reaching time-difference (TDOA) and angle of arrival (AOA)
Method compare, the method based on RSS is more feasible.On the one hand, such a method can utilize existing wireless infrastructure, so that
Capital expenditure (CAPEX) can be reduced.On the other hand, the radiotechnics of Current standards commercialization, such as Wi-Fi, ZigBee, have
Source radio frequency identification (RFID) and bluetooth etc. all provide RSS measurements, thus can apply across different system platforms and be measured on RSS
Identical algorithms.However, there is complicated multipath effect in uncertain indoor environment, including shade (such as signal quilt
Stop), reflection (such as radiobeam run into object then rebound), (such as radiobeam meets with obstruction and dissipates after thing diffraction
Hold) and refraction (such as radiobeam during different medium by that can bend), etc..Due to these effects, RSS is surveyed
Amount can decay in an unpredictable manner.Use direction figure RA can improve the accuracy of the alignment system based on RSS.However,
As described above, the RA used in the alignment system based on RSS is usually very big, and it is difficult to integrate into mimo antenna array.
In this case, it is necessary to designed size and thickness is smaller and high efficiency antenna that bandwidth is larger arrangement, to be applied to
Mimo system.
A kind of method for increasing bandwidth of operation in the case where not increasing antenna size has been proposed.Fig. 1, Fig. 2 (a),
Fig. 2 (b) and Fig. 2 (c) respectively illustrate the perspective view of the example antenna 100 for adopting this method design, top view, side view and
Bottom view.As shown in Figure 1, antenna 100 includes circular radiation piece 110, ground connection dielectric-slab 120 and feed tab 130.In this example
In, the thickness H=3.7mm of dielectric-slab 120, it can select RogersRT/5880 (tm) dielectric-slabs.Dielectric-slab
120 dielectric constant is 2.2, and dielectric loss angle is 0.0009.Feed tab 130 is connected with feed probes 140, with radiation fin
110 spacing hl.Arrange that five support column 150-1 to 150-5 (are referred to as supporting around feed tab 130 and feed probes 140
Column 150).
As shown in Fig. 2 (c), support column 150-1 is grounded via two coupled capacitors 210.Support column 150-2 to 150-5 can
To be grounded by PIN diode 220, or this four support columns are earth-free.Direct current (DC) control signal can be by radio frequency
Fed after choke coil 230 by support column 150-1, as shown in Fig. 2 (b).Correspondingly, radiation fin 110 is passed through from support column 150-1
Remaining support column 150-2 to 150-5 is arrived again forms DC channel.By this antenna arrangement can obtain broadside antenna pattern and
Both radiation regimes of cone shaped radiation directional diagram.
In addition, adaptively applied also directed to wave beam, it is proposed that a kind of square loop antenna (SLA).SLA usually has four
Distributing point.When encouraging a distributing point successively, wave beam can be made to be directed toward four different space quadrants successively, it is possible thereby to produce
Raw four kinds of radiation regimes.It is limited however, such a antenna causes it to realize there are following three major defect：(a) its thickness mistake
Thickness, is quarter-wave；(b) its bandwidth is limited；(c) antenna pattern has very strong secondary lobe.
For these problems, it has been proposed that some solve method.A kind of method is the loading mixing high impedance table on SLA
Face (HHIS).Fig. 3 shows the perspective view for the example SLA300 for being loaded with HHIS.As shown in the figure, SLA 300 divides on four sides
Distributing point 305,310,315 and 320 is not disposed with.The method of this loading HHIS can be substantially reduced the thickness of antenna.For example,
The thickness of antenna can be decreased to λ at the frequency of 4.7GHz0/13.6.But it is such a design it is more complicated in realization.Example
As, it is necessary to beat many holes, as shown in the figure.This wastes many manpower and materials costs.In addition, the size of antenna is still very big.
Fig. 4 shows another SLA400, it uses capacitive coupling.As shown in the figure, the length on four sides of SLA 400 is
ll, the length of dielectric-slab is L.A feed 405,410,415 and 420 is arranged on each side.It is each feed 405,410,
At 415 or 420, the metal patch of a rectangle is arranged, its width is lpl, thickness wpl.Each between metal patch and antenna
It is w to form a widthlGap, so as to fulfill capacitive coupling.In addition, an opening is arranged on each side of antenna 400, it is wide
Spend for gl.Such a arrangement can be substantially reduced the thickness of antenna, and realize simpler.However, in such a antenna arrangement, often
A metal patch forms single resonance with corresponding antenna aperture, so as to result in certain bandwidth of operation loss.
In order to solve these and other potential problems, embodiment of the disclosure provides a kind of polygon loop antenna,
Each side of antenna is made of a radiating element.Even number capacitive device is arranged on each side of antenna, and at two
A feed element is arranged between adjacent capacitive device.Compared with traditional antenna, polygon in accordance with an embodiment of the present disclosure
Loop antenna size and thickness is smaller and broader bandwidth, and more adaptive radiation beam can be formed.

Go.It this will be described further hereinafter.In this example, each radiating element 510 is embodied as a metal conductive strips, uses
In realizing corresponding radiation function.As shown in Fig. 5 (b), the example lengths l of metal conductive stripsa=40mm, example width wa=
1.6mm.In general, the resonant frequency of SLA is inversely proportional with its average circumferential length.The thus average week of the antenna 500 in this example

In example, it should be as close to feed port., can be by adjusting the capacitive value loaded in order to further reduce the thickness of antenna
Realized with its position, but the bandwidth of operation or radiation efficiency of antenna can be influenced at the same time.In certain embodiments, capacitive device
520-1 and 520-2 is embedded into corresponding metal conductive strips (i.e. radiating element 510-1).
In accordance with an embodiment of the present disclosure, antenna 500 further includes multiple feed element 530-1,530-2,530-3 and 530-4
(being referred to as feed element 530).Arrange that a feed is single on each side of antenna 500, between two adjacent capacitive devices 520
Member 530.In this example, each feed element 530 (is referred to as presenting including feed probes 540-1,540-2,540-3 and 540-4
Electric probe 540).The size of feed probes 540 can be designed according to being actually needed.In this example, feed probes 540 is straight
Footpath is 1.3mm.
As shown in the figure, feed probes 540 (are referred to as presenting in corresponding distributing point 550-1,550-2,550-3 and 550-4
550) electricity point is in contact at place with radiating element 510.Feed probes 540 are used to receive electric feed signal.Then, as described above, by spoke
Electric feed signal is radiate by emitter part 505.
It is similar with traditional SLA, a feed probes (such as feed probes 540-1) can be fed successively and at the same time
Other feed probes (such as feed probes 540-2,540-3 and 540-4) open circuit is kept to produce multiple slant beams to control, from
And form multiple radiation regimes.Caused slant beam is opposite with the direction of corresponding distributing point.In this way, antenna 500
A variety of slant beams can be generated, every kind of slant beam can be by selecting corresponding feed port to control.
In order to further enhance the performance of antenna, in some embodiments it is possible to which capacitive device 520 is positioned symmetrically in
The both sides of corresponding distributing point 550.The spacing of capacitive device 520 can be designed according to being actually needed.In this example, two
The spacing of adjacent capacitive device 520 is 4mm.
Antenna 500 further includes hexagon dielectric-slab 560.In this example, dielectric-slab 560 employs three layers of laminated plate material
Material, such as Taconic RF-60 (tm) laminate sheet material can be selected.560 gross thickness of dielectric-slab is 5.4mm, the long L=in side
80mm.As shown in the figure, in this example, one of the angle that is formed between two adjacent radiating elements 510 and dielectric-slab 560
Side is opposite, so as to further reduce the size of antenna.It should be appreciated that according to the actual requirements dielectric-slab can be designed as appointing
Meaning suitable shape.The scope of the present disclosure is not limited in this respect.
In accordance with an embodiment of the present disclosure, there is provided a kind of size for reducing traditional antenna and thickness and increase bandwidth of operation
Method.The antenna proposed can be such as Shared aperture reconfigurable antenna, its size with can based on select each subcomponent
Reconfigurable antenna compares smaller.Its thickness thickness at 3.5GHz is approximately 0.063 λ0, the thickness with the traditional antenna 300 shown in Fig. 3
Degree (such as 0.074 λ0) thinner, with antenna thickness (0.045 λ shown in Fig. 40) thick but structure 3 shown in Fig. 4 times can be obtained
Bandwidth.Size and the cost and compactedness of thickness and antenna are closely related.The reduction of size and thickness causes mimo antenna battle array
