Description
technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, to a liquid crystal antenna and a manufacturing method thereof. Background technique [0002] Liquid crystal antenna is a new type of array antenna based on liquid crystal phase shifter, which is widely used in satellite receiving antenna, vehicle radar, base station antenna and other fields. Based on the anisotropic characteristics of liquid crystal molecules, the liquid crystal antenna uses electrical signals to control the arrangement of liquid crystal molecules, thereby changing the microwave dielectric parameters of each phase shifter unit, thereby controlling the phase of the microwave signal in each phase shifter unit, and finally realizing antenna radiation. Control of beam pointing. Liquid crystal antennas have broad application prospects in satellite receiving antennas, vehicle radars, 5G base station antennas and other fields. [0003] In...
