Abstract: A phase shifter and a manufacturing method thereof and an antenna and a manufacturing method thereof are provided. The phase shifter includes: first and second substrates opposite to each other; a first electrode provided on the first substrate and configured to receive a ground signal; a second electrode provided on a side of the second substrate facing towards the first substrate; liquid crystals encapsulated between the first substrate and the second substrate and driven by the first electrode and the second electrode to rotate; and a support structure provided between the first substrate and the second substrate and including a first spacer. The first spacer is located on a side of the second electrode facing away from the second substrate, and an orthographic projection of the first spacer on the second substrate is within an orthographic projection of the second electrode on the second substrate.
