Claim 4:
5. The phase shifter of claim 2, wherein for any one of the phase control units, a height of each of the plurality of driving structures in the direction away from the substrate is greater than the height of the signal electrode in the direction away from the substrate, a number of the driving structures whose orthographic projections are between the orthographic projections of the first reference electrode and the signal electrode on the substrate is plural, and heights of the driving structures whose orthographic projections are between the orthographic projections of the first reference electrode and the signal electrode on the substrate monotonically decrease in a direction pointing from the first reference electrode to the signal electrode; a number of the driving structures whose orthographic projections are between the orthographic projections of the second reference electrode and the signal electrode on the substrate is plural, and heights of the driving structures whose orthographic projections are between the orthographic projections of the second reference electrode and the signal electrode on the substrate monotonically decrease in a direction pointing from the second reference electrode to the signal electrode; or,
the height of each of the plurality of driving structures in the direction away from the substrate is smaller than the height of the signal electrode in the direction away from the substrate, the number of the driving structures whose orthographic projections are between the orthographic projections of the first reference electrode and the signal electrode on the substrate is plural, and the heights of the driving structures whose orthographic projections are between the orthographic projections of the first reference electrode and the signal electrode on the substrate monotonically increase in the direction pointing from the first reference electrode to the signal electrode; the number of the driving structures whose orthographic projections are between the orthographic projections of the second reference electrode and the signal electrode on the substrate is plural, and the heights of the driving structures whose orthographic projections are between the orthographic projections of the second reference electrode and the signal electrode on the substrate monotonically increase in the direction pointing from the second reference electrode to the signal electrode.
