Abstract

The embodiment of the invention provides a liquid crystal phased-array antenna. According to the liquid crystal phased-array antenna provided by the embodiment of the invention, the distance between the orthographic projection of a first transmission line and the orthographic projection of a second transmission line on a first substrate and the orthographic projection of a phase shift unit on the first substrate is set to be within the first distance range, so that the size of the induced current generated by the phase shift unit and the first transmission line and the size of the induced current generated by the phase shift unit and the second transmission line can be reduced, or the possibly generated induced current can be greatly reduced, the size of the induced current generated in the first transmission line and / or the second transmission line can be reduced, then the influence of the phase shift unit on the first transmission line and / or the second transmission line can be reduced, and the normal work of the liquid crystal phased-array antenna can be ensured.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular, the present application relates to a liquid crystal phased array antenna. Background technique [0002] With the development of communication technology, there are more and more types of antennas. At present, liquid crystal phased array antennas are one of the important research and development directions in the field of wireless communication. Liquid crystal phased array antenna is a kind of using the dielectric anisotropy of liquid crystal, providing deflection voltage to the upper and lower sides of the liquid crystal layer through the transmission line, controlling the deflection direction of liquid crystal to change the phase shift size of the phase shifter, so as to adjust the phase shifter of the phased array antenna Directional antenna. [0003] The liquid crystal phased array antenna contains multiple transmission lines. In the currently used ...
