Abstract
A liquid crystal antenna, a manufacturing method and a driving method thereof, and a communication device are disclosed. The liquid crystal antenna includes a first substrate and a second substrate provided opposite to each other, a liquid crystal layer, a plurality of microstrip patch antenna structures and a ground electrode. The liquid crystal layer and the plurality of microstrip patch antenna structures are located between the first substrate and the second substrate; the ground electrode is located on a side of the first substrate away from the liquid crystal layer. Each of the plurality of microstrip patch antenna structures is configured to receive a voltage signal that controls deflection of liquid crystal molecules in the liquid crystal layer and to receive or transmit a microwave signal.
