Beam antenna array.
Background technology
With the increase of the explosion type of data message amount, increasing requirement is proposed to the capacity of communication system, especially
It is place king-sized in flow of the people, such as, square, station, scenic spot, the ground such as dormitory.On the one hand, can be by bandwidth in band
Or carrier bandwidths are increasing channel capacity.Because the bandwidth of single antenna is generally narrow, so many passband base station sky is usually used
Linear array to support multiple wireless system standards simultaneously.On the other hand it is also possible to pass through to reduce the coverage of antenna for base station, that is,
The capacity to increase channel for the quantity of increase antenna.But these methods frequently can lead to the increase of area occupied and construction cost.

The design size of array is as follows：Lx=110mm, Ly=60mm, Hx=45mm, Hy=50mm, Gx=1000mm, Gy
=340mm.
In this embodiment, working frequency range 1710-2170MHz and 2490-2690MHz of two subarrays, 3G frequency range
Subarray high efficient radiation in its working frequency range 1710-2170MHz, in band outer i.e. LTE frequency range (2490-2690MHz) suppression spoke
Penetrate；Meanwhile, the subarray of LTE frequency range high efficient radiation in its working frequency range 2490-2690MHz MHz, in the outer i.e. 3G frequency range of band
(1710-2170MHz) suppression radiation.Therefore, the radiation between two subarrays does not interfere with each other, thus reduce interfering,
Reach higher interport isolation.
As shown in Figure 10, be one embodiment of the invention provide the no additional losser circuit being operated in 3G frequency range filtering
Reflectance factor S parameter-the frequency of antenna element.It can be seen that working frequency range is to have two modes of resonance in 1710-2170MHz,
In S11- frequency curve, S11 is less than -15dB in 3G frequency range.In S21- frequency curve, S21 in 3G frequency range be less than-
30dB.
As shown in figure 11, be one embodiment of the invention provide the no additional losser circuit being operated in LTE frequency range filter
Reflectance factor S parameter-the frequency of wave antenna unit.It can be seen that working frequency range is also to have two resonant modes in 2490-2690MHz
Formula, in S11- frequency curve, S11 is less than -15dB in LTE frequency range.In S21- frequency curve, S21 is low in LTE frequency range
In -30dB.
As shown in Figure 12,13, it is outside the nothing being operated in 3G frequency range and LTE frequency range that one embodiment of the invention provides respectively
Plus 1 port (Figure 12) of the filter antenna unit of losser circuit and 2 ports (Figure 13) gain-frequency curve when encouraging respectively,
Can see that the gain in 3G frequency range is about 8.5dBi, the gain in LTE frequency range simultaneously is about 8.2dBi, the increasing of radiation zero
Benefit is below -20dBi.Passband edges are precipitous, and sideband suppression is substantially, selectively good, and carries interior flat gain.
As shown in Figure 14,15,16,17,18, be present example provide low-and high-frequency filter a period of time intertexture compact many
Beam antenna array obtains reflectance factor-frequency, the simulation result figure of transmission coefficient-frequency.As can be seen that in whole 3G frequency range
(1710-2170MHz), and in LTE frequency range (2490-2690MHz), the S11 of this array is less than -22dB, and the coupling of this port is described
Well.In whole 3G frequency range (1710-2170MHz) and LTE frequency range (2490-2690MHz), the S12 of this array is less than-
25dB, illustrates the effect very little that intercouples between the subarray of this array, and interport isolation is high.Meanwhile, as Figure 17,18 institutes
Show, in whole 3G frequency range (1710-2170MHz) and LTE frequency range (2490-2690MHz), the beam isolation of this array reaches
15dB, illustrates that the beam isolation of this array is good.Figure 19-26 sets forth this aerial array 2.0GHz and 2.6GHz each
The horizontal radiation pattern of wave beam, equally illustrates that this aerial array has stable antenna pattern.
The embodiment of the present invention has the advantage that：
1st, integrating filtering characteristic and radiation characteristic, aerial array itself has filtering performance, and passband edge is precipitous, and sideband suppresses
Substantially, there is good frequency selective characteristic, need not additional duplexer or uncoupling lattice network, overcome using additional duplex
Device or uncoupling network easily cause the big shortcoming of loss；
2nd, this aerial array is applied to 3G frequency range and LTE frequency range, it is achieved that port in the case of without uncoupling circuit
High-isolation, suppression face frequency interference, improve the performance of base station transceiver；
3rd, interleaved arrangement between the subarray of this aerial array, High frequency filter a period of time and low frequency filtering a period of time filter a period of time friendship
Knit the array that arrangement is formed, by being fed in interior feeding network design containing butler matrix, it is possible to achieve compact
Type multi-beam base-station antenna array, compares and separates the size that arrangement group battle array reduces array；
4th, total is mainly made up of metal patch, metallization via, dielectric-slab through hole and ring shaped slot, and structure is simple,
Design is easy.
5th, this aerial array is multiple-beam array, and wave beam is narrow, and high gain is it is adaptable to sector divides and can cover farther out
Distance.
6th, the beam isolation effect of this aerial array is good.
The embodiment that the present invention provides is applied to wireless mobile communication base station field, can be applicable to various types of wireless communication systems
Reception and transmitting equipment in, due to the filtering characteristic of the present invention, be particularly well-suited to lead in open complicated multiband multi-standard
In letter scene, it is operated in 3G frequency range and the antenna for base station of LTE frequency range.Benefit from the collection of filtering characteristic and radiation characteristic simultaneously
Become, it is suitable for the integration of mobile radio system equipment and integrated, reduction design requirement, improve communication and set
The ability of standby anti-adjacent frequency interference.
High frequency filter a period of time of the embodiment of the present invention and low frequency filtering a period of time interweave the formed array of arrangement, by containing
Butler matrix is fed in interior feeding network, it is possible to achieve compact multi-beam base-station antenna array.Example compact
Type base-station antenna array realizes 120 ° of sectors of two wave cover in horizontal plane, and vertical plane forms the narrow beam radiation side of Sidelobe Suppression
Xiang Tu.There is filtering characteristic in paster a period of time due to interweaving, and the effect of intercoupling between high frequency a period of time and low frequency a period of time subtracts significantly
Little.
