ANTENNA WITH ADJUSTABLE BEAMWIDTH

WIPO Patent Application WO/2020/042718

A1

Disclosed is an antenna with an adjustable beamwidth. 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 changeover switch assembly. The radiation device comprises a first radiation unit and a plurality of second radiation units. Each second phase shift output port is correspondingly connected to each of the second radiation units on a one-to-one basis. An output port of the first output branch is connected to an input port of the phase shifter, and an input port thereof is connected to an output port of the first input branch by means of the changeover switch assembly. An output port of the second output branch is connected to the first radiation unit, and an input port thereof is connected to an output port of the second input branch by means of the changeover switch assembly. An input port of the second input branch is connected to a first phase shift output port. The output port of the first input branch is connected to the input port of the second output branch by means of the changeover switch assembly. Thus, the beamwidth of a vertical plane of an antenna can be changed, and the requirements for different coverage scenarios can be met.
