Abstract
A phase shifter, an electrically regulated antenna, a network device, and a phase shifter manufacturing method are provided. The phase shifter includes: a shielding member, and an adjustable dielectric layer provided in a shielding space formed by the shielding member; the adjustable dielectric layer includes a line layer and a dielectric member. The line layer includes 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.
