Abstract
A liquid crystal antenna and a manufacturing method thereof are disclosed. The liquid crystal antenna includes: an antenna array including a first substrate and a second substrate arranged opposite to each other and configured to change a phase of an electromagnetic wave signal fed into the liquid crystal antenna to transmit or receive a beam in a preset direction; and an inertial navigation element configured to determine a motion parameter of the liquid crystal antenna in a navigation coordinate system, the inertial navigation element is disposed on a side of the second substrate facing the first substrate; and the antenna array adjusts the preset direction according to the motion parameter acquired by the inertial navigation element.
