Abstract
Provided are a liquid crystal antenna, a manufacturing method thereof and a communication device having the liquid crystal antenna. The liquid crystal antenna includes a first metal electrode, a second metal electrode, a third metal electrode, at least two oppositely arranged substrates, and a liquid crystal layer located between the two oppositely arranged substrates. The two oppositely arranged substrates each include a light transmission area. The first metal electrode, the second metal electrode and the third metal electrode within the light transmission area each are a hollowed-out structure, and the light transmission area can be used to test a cell thickness of the liquid crystal cell. Since the cell thickness can be measured, other process parameters can be matched and adjusted, so that a mass production yield of the liquid crystal antennas is improved.
