1. A phase shifter, comprising:
a plurality of phase shift units coupled in sequence, wherein at least one phase shift unit of the plurality of phase shift units includes:
a first conductive structure including at least one first transmission line, and a second transmission line connected to the at least one first transmission line, the second transmission line being configured as an inductive load, wherein the at least one first transmission line of the first conductive structure includes two first transmission lines, the second transmission line is connected to the two first transmission lines; and the two first transmission lines are configured to transmit two signals that are differential mode signals of each other; and
a second conductive structure including at least one third transmission line, each third transmission line of the at least one third transmission line being configured to form a capacitor with a first transmission line of the two first transmission lines, wherein
the first transmission line of the two first transmission lines, a corresponding third transmission line of the at least one third transmission line and the capacitor constitute at least a portion of a phase shift communication path of the phase shifter.
