Abstract
A phase shifter and a manufacturing method thereof, a liquid crystal antenna and a communication device are provided. The phase shifter includes: a first substrate and a second substrate which are oppositely arranged; and a sealing frame structure located in peripheral regions of the first substrate and the second substrate for fixing relative positions of the two substrates to form a gap for accommodating a liquid crystal material; wherein the sealing frame structure includes a support, and sealant for bonding to the first substrate, on the support. It is able to facilitate the increase in the adjusting range of the resonant frequency of the liquid crystal antenna by the phase shifter and the manufacturing method thereof.
