Further, the array antenna shown in fig. 1 or fig. 2 can only satisfy coverage of a fixed scene, and cannot change a coverage policy with a change of a usage scene of the user equipment, and cannot satisfy coverage requirements under different usage scenes.
Based on this, the embodiment of the invention provides an antenna which can meet the coverage requirements in different use scenes.
Referring to fig. 3, fig. 3 is a schematic structural diagram of an antenna provided in an embodiment of the present invention, where the antenna includes an array module 302 and a control module 301, where the array module 302 includes a feed network 3021 and at least two sub-arrays 3022, the feed network 3021 includes a plurality of first phase shift devices 3024, the sub-array 3022 is provided with at least two radiation elements 3023, and two adjacent radiation elements 3023 are connected through the first phase shift devices 3024; the control module 301 is configured to obtain user equipment information obtained after the array module 302 performs beam polling, and control the first phase shifting device 3024 to act according to the user equipment information, so that the array module 302 performs beam reconstruction, and the control module 301 is connected to the first phase shifting device 3024.
It is understood that the ue information may be obtained by other means besides the beam polling performed by the array module 302, for example, the ue information may be collected by another collecting device and then sent to the control module 301.
In one embodiment, the first phase shifter 3024 may be a digital phase shifter, the digital phase shifter is an analog device, and digital-analog hybrid forming may be performed in the vertical direction by disposing the digital phase shifter between two adjacent radiation units 3023, so that a larger scan angle coverage in the vertical direction is realized, which is beneficial to expanding the scan range of beam polling of the array module 302; the beam reconstruction can be realized by carrying out analog forming in the vertical direction, and the refinement degree of the beam reconstruction is improved.
In the antenna provided in the embodiment of the present invention, the control module 301 obtains the user equipment information obtained after the array module 302 performs the beam polling, and controls the first phase shift device 3024 to act according to the user equipment information, so as to enable the array module 302 to perform the beam reconstruction, because the first phase shift device 3024 is arranged between two adjacent radiation units 3023 in the sub-array 3022 of the array module 302, the refinement degree of the beam reconstruction is favorably improved, so that the beam finally transmitted by the antenna can better adapt to the requirement of the user equipment, thereby improving the rationality of the antenna resource allocation, and meeting the coverage requirements in different usage scenarios.
Moreover, since the first phase shifting device 3024 is disposed between two adjacent radiation elements 3023 in the sub-array 3022 of the array module 302, the scanning range of the beam polling of the array module 302 can be expanded.
