1. A phase shifter, comprising:
a shielding member, and an adjustable dielectric layer arranged in a shielding space formed by the shielding member, wherein
the adjustable dielectric layer comprises a line layer and a dielectric member; the line layer comprises a feed circuit and an empty slot arranged corresponding to the feed circuit and used to form an air strip line; the dielectric member is inserted into the empty slot; and a dielectric constant of the feed circuit is changed by controlling a depth of the dielectric member inserted into the empty slot;
wherein the line layer comprises a line carrying plate; the line carrying plate comprises two line setting surfaces; the line layer further comprises a first supporting plate and a second supporting plate which are respectively arranged on the two line setting surfaces; a through slot matched with a shape of the feed circuit formed on the line setting surface corresponding to the first supporting plate and/or the second supporting plate is formed in the first supporting plate and/or the second supporting plate, so that when the carrying plate is fitted to the first supporting plate and/or the second supporting plate, the feed circuit is embedded into the through slot.
