Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to an antenna unit, an antenna, and a communication device.
Background
With the construction of the fifth generation (5rd generation, 5G) network, the scene demand for scene blind-compensation becomes more obvious. In some construction-intensive scenes, for example, in particular in residential or commercial blocks, higher demands are made on the coverage of network devices. Taking a residential area as an example, there are often many buildings of different sizes in a residential area. Due to limitations in building height, width, and distance between different buildings, the lobe width of the antenna in the network device needs to be adaptively adjusted to achieve flexible coverage.
At present, a conventional antenna is shown in fig. 1, and fig. 1 is a schematic diagram of an antenna structure in the prior art. The antenna comprises 4 antenna array units (also called as an array) and a phase shifter connected with the antenna array units. The antenna is adjusted to a vertical direction (opposite to the sea level direction) by the phase shifter, and only one antenna array unit is reserved, so that the purpose of reducing the beam width in the vertical direction is achieved.
However, after the above-mentioned solution uses the phase shifter to adjust the antenna array elements, the beam width of the antenna in the horizontal direction (i.e. parallel to the sea level direction) is not changed, which causes the problem of cross-area interference of the network device in the horizontal direction.
