Abstract

The invention discloses a liquid crystal antenna, a driving method thereof and a communication device and aims to reduce the cost of liquid crystal antenna development. The liquid crystal antenna comprises a first substrate, a second substrate, a liquid crystal layer arranged between the first substrate and the second substrate, antenna units arranged between the first substrate and the second substrate in an array way, and a control module, wherein the first substrate and the second substrate are arranged oppositely, and each antenna unit comprises a first electrode arranged on the side, close to the liquid crystal layer, of the first substrate, a second electrode arranged on the side, close to the liquid crystal layer, of the second substrate. The control module comprises a first outputend and a second output end and outputs voltage signals opposite in polarity through the first output end and the second output end respectively, the first electrodes are electrically connected with the first output end, and the second electrodes are electrically connected with the second output end.

Description

technical field [0001] The invention relates to the technical field of liquid crystal antennas, in particular to a liquid crystal antenna, a driving method thereof, and communication equipment. Background technique [0002] Currently, a DAC (Digital to analog converter, digital-to-analog converter) is used to drive the liquid crystal antenna to provide the antenna voltage. With the increase in the number and size of antennas, the number of DACs is further increased, so that a large number of DACs will occupy a large space, and at the same time, a large amount of cost will be consumed when developing a DAC driver board. Contents of the invention [0003] The invention provides a liquid crystal antenna, its driving method and communication equipment, which are used to reduce the cost of developing the liquid crystal antenna. [0004] An embodiment of the present invention provides a liquid crystal antenna, including: [0005] a first substrate and a second substrate arrang...
