Claim 10:
11. A phase shifter, comprising: a first substrate, a second substrate, a dielectric layer, a transmission line, a ground electrode and at least one auxiliary electrode, wherein the first substrate and the second substrate are opposite to each other, the dielectric layer is between the first substrate and the second substrate, the transmission line is between the second substrate and the dielectric layer, the auxiliary electrode is between the first substrate and the dielectric layer, and the ground electrode is on a side of the second substrate distal to the dielectric layer; a dielectric constant of the dielectric layer changes with a voltage between the auxiliary electrode and the transmission line;
an orthographic projection of the transmission line on the first substrate overlaps with an orthographic projection of the auxiliary electrode on the first substrate, and a portion of the orthographic projection of the transmission line on the first substrate exceeds the orthographic projection of the auxiliary electrode on the first substrate,
wherein the at least one auxiliary electrode is grounded, and
wherein the at least one auxiliary electrode comprises a plurality of auxiliary electrodes coupled to the ground electrode through a plurality of connection members, respectively, and each of the plurality of connection members penetrates through the dielectric layer and the second substrate and is insulated and separated from the transmission line.
