Claim 0:
1. A phase shifter, comprising:
a substrate;
a signal transmission structure disposed on the substrate; and
a phase adjustment structure disposed on the substrate, wherein the phase adjustment structure includes:
a conductive structure;
at least one semiconductor structure disposed between the signal transmission structure and the conductive structure, orthogonal projections, on the substrate, of the signal transmission structure, the conductive structure, and the at least one semiconductor structure overlapping with one another;
a first insulating layer disposed between the conductive structure and the at least one semiconductor structure; an orthogonal projection, on the substrate, of the first insulating layer being located at least in a region in which the orthogonal projections, on the substrate, of the conductive structure and the at least one semiconductor structure overlap; and
at least one first bias voltage line electrically connected to the conductive structure.
