Abstract

The invention discloses an antenna with an adjustable wave width. The antenna comprises a switch device, a radiation device and a phase shifter; the switch device comprises a first input branch, a second input branch, a first output branch, a second output branch and a switching switch component; the radiation device comprises a first radiation unit and a plurality of second radiation units; eachsecond phase-shifting output port is connected with each second radiation unit in a one-to-one correspondence mode; the output port of the first output branch is connected with the input port of the phase shifter, and the input port is connected with the output port of the first input branch through the switching switch component; the output port of the second output branch is connected with the first radiation unit, and the input port is connected with the output port of the second input branch through the switching switch component; the input port of the second input branch is connected witha first phase-shifting output port; and the output port of the first input branch is connected with the input port of the second output branch through a switching switch component. Therefore, the beam width of the antenna vertical plane can be changed, and the requirements of different coverage scenes can be met.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an antenna with adjustable wave width. Background technique [0002] With the development of mobile communication, in order to meet the coverage and capacity requirements of antennas, adding sites has become an inevitable choice. After the large-scale construction of macro base stations, in-depth coverage and blind coverage in residential areas and commercial streets have become the focus of major operators. The cost of adding traditional macro stations in these areas is high, and the antenna size is large. address is difficult. At present, micro-station antennas or low-gain directional antennas are often used for coverage or blind filling. [0003] During the implementation process, the inventor found at least the following problems in the traditional technology: the vertical beam width of the traditional antenna is fixed, and the corresponding coverage area is also relativel...
