Claim 3:
4. The phase shifter of claim 1, wherein the connection structure on the first signal transmission structure and the connection structure on the second signal transmission structure each comprise: a reference electrode on a side of the first substrate distal to the second substrate, a coupling branch and a delay branch on a side of the first substrate proximal to the second substrate, and a receiving electrode on a side of the second substrate proximal to the first substrate; and the first signal transmission structure and the second signal transmission structure each comprise a power divider;
the phase shifting structure comprises: a first transmission line on a side of the first substrate proximal to the second substrate; and a second transmission line on a side of the second substrate proximal to the first substrate,
wherein in each of the first and second signal transmission structures, each of the coupling branch and the delay branch forms a current loop with the reference electrode;
in each of the first and second signal transmission structures, a first end of the coupling branch and a first end of the delay branch are both connected to respective signal output ends of the power divider; a second end of the delay branch is connected to the first transmission line in the phase shifting structure; and a second end of the coupling branch is floated;
in each of the first and second signal transmission structures, an orthographic projection of the coupling branch on the second substrate at least partially overlaps with an orthographic projection of the receiving electrode on the second substrate; the receiving electrode is connected to the second transmission line of the phase shifting structure.
