Abstract
Provided are a liquid crystal phase shifting unit, a method for manufacturing the same, a liquid crystal phase shifter, and an antenna, which relate to the technical field of phase shifting. A liquid crystal filling region () is supported steadily by a support structure (), which increases the transmission stability of a microwave signal. A space between a first substrate () and a second substrate () of the liquid crystal phase shifting unit includes the liquid crystal filling region (). A microstrip line () is provided on a surface of the first substrate () facing towards the second substrate (). An orthographic projection of the microstrip line () on the first substrate () is located in the liquid crystal filling region (). The support structure () is provided between the first substrate () and the second substrate () and in the liquid crystal filling region (). The orthographic projection of the support structure () on the first substrate () does not overlap the microstrip line (), which is used for shifting a phase of a microwave signal.
