PHASE SHIFTER, BASE-STATION ANTENNA AND BASE STATION

WIPO Patent Application WO/2024/067021

A1

The present application relates to the technical field of antennas, and specifically provides a phase shifter, a base-station antenna and a base station. The phase shifter comprises a phase shifter assembly and a swing arm assembly. The phase shifter assembly comprises a substrate, a coupling structure, a main feeder line and at least one strip line, wherein the coupling structure is provided with an arc-shaped coupling face; one end of the main feeder line is electrically connected to the coupling face, and the other end thereof is a signal input end, which is used for receiving a first electrical signal; and each strip line is provided with an arc-shaped section and two signal output ends, which are used for outputting second electrical signals. The swing arm assembly is rotatably mounted on the substrate, and one end of the swing arm assembly is electrically connected to the coupling face, and the other end thereof is electrically connected to the arc-shaped section. In each strip line, compared with the first electrical signal received by the signal input end, phase changes of the second electrical signals outputted from the two signal output ends are equal in terms of size and have opposite directions, such that the phase difference symmetry of the phase shifter can be improved and increased.
