Embodiment 1

[0021] Such as figure 1 As shown, the antenna provided by the embodiment of the present invention includes a hierarchical beam characteristic control structure and a radiation unit 3; the hierarchical beam characteristic control structure includes a beam characteristic control device 1-1 at the top layer, and at least two beam characteristic control devices at the bottom layer Control devices 1-4 to 1-7; each beam characteristic control device has an input end and two output ends; wherein, the input end of the beam characteristic control device on the top layer is used to receive signals, and the two output ends directly or indirectly The received signals are assigned to the input ends of at least two bottom beam characteristic control devices, and at least two bottom beam characteristic control devices redistribute the respective assigned signals and then output them to the radiation from their corresponding output ports. Unit 3.

[0022] The beam characteristic control devi...

Embodiment 2

[0025] This embodiment is basically the same as Embodiment 1, the difference is: as figure 2 As shown, each output terminal of the bottom beam characteristic control devices 1 - 4 to 1 - 7 is connected to a plurality of radiation units 3 . As a preferred solution, the radiation units 3 on each output end are arranged vertically. For the antenna with multiple radiation units 3, using one output to control multiple radiation units 3 can simplify the structure of the antenna, and can also achieve different lobe widths between 0° and 70°, such as 3°, 6°, 10° °, 12°, 33°, 45°, 60°, etc. Of course, the radiating elements on each output terminal can also be arranged horizontally, such as image 3 shown; or arranged diagonally at an angle.

[0026] In the embodiment of the present invention, at least one beam characteristic control device is provided with a phase control device on an output end or an input end. As a preferred solution, phase control devices 2-1 to 2-3 are provide...

Embodiment 3

[0030] This embodiment is basically the same as Embodiment 2, except that the beam characteristic control device 1 is composed of a power divider, a phase shifter and an electric bridge 13; the power divider and the phase shifter are integrated designs, and the phase shifter Both outputs are connected to the bridge 13 .

[0031] Specifically, the structure of the power divider and phase shifter can be as follows Image 6 As shown, the signal line is connected to a rotating shaft 14, and the phase of the two signals is changed by rotating the pointer of the rotating shaft 14 on the arc 15; the structure of the power divider and the phase shifter can also be as follows Figure 7 As shown, a slidable medium 16 is set on the transmission line of the power division part, and the electrical length of the two channels is changed by sliding the medium 16, thereby changing the phase of the two signals.

[0032] The common point of the above two implementations is that the phases of th...

Abstract

An antenna and antenna control system are disclosed in the embodiments of the present invention which belongs to the technical field of communications equipment. The present invention realizes to change the wave beam width of the vertical plane of the antenna. The antenna includes a level wave beam characteristics control structure and radiation element; the level wave beam characteristics control structure includes a wave beam characteristics control device on the top level and at least two wave beam characteristics control devices on the bottom level; each wave beam characteristics control device has one input end and two output ends; wherein the input end of the wave beam characteristics control device on the top level is used to receive a signal and the two output ends assign the received signal directly or indirectly to the input ends of the at least two wave beam characteristics control devices on the bottom level, and the at least two wave beam characteristics control devices on the bottom level reassign the assigned signal and output it to the radiation element in respective output ends of the at least two wave beam characteristics control devices on the bottom level. The present invention is applied to improve the wave beam width of the antenna.

Description

technical field [0001] The invention belongs to the technical field of communication equipment, and in particular relates to an antenna and an antenna control system. Background technique [0002] With the development of mobile communication technology, there are more and more functional requirements for base station antennas. The control requirements for beam characteristics are getting higher and higher, and the beam characteristics include but are not limited to azimuth angle, downtilt angle, horizontal beam width, vertical beam width, etc. At present, there is a technical solution to control the beam pointing by adjusting the azimuth and downtilt angle of the antenna, but the adjustable beam width, especially the adjustable beam width in the vertical plane, has not yet been realized. Contents of the invention [0003] Embodiments of the present invention provide an antenna and an antenna control system, capable of changing the vertical bandwidth coverage of the antenn...
