Classification: CPC H | IPC H

Claim 0:
1. A liquid crystal antenna, comprising:
a first substrate;
a second substrate opposite to the first substrate; and
a liquid crystal layer disposed between the first substrate and the second substrate,
wherein:
a first conductive layer is disposed on a side of the first substrate facing toward the second substrate, the first conductive layer including a plurality of first driving electrodes;
a second conductive layer is disposed on a side of the second substrate facing toward the first substrate, the second conductive layer at least including a plurality of radiation electrodes, a power division network structure, and a plurality of microstrip lines, wherein:
the power division network structure is connected to a signal input terminal;
one end of a microstrip line of the plurality of microstrip lines is connected to the power division network structure;
another end of the microstrip line is respectively connected to the plurality of radiation electrodes; and
an orthographic projection of a first driving electrode on the second substrate at least partially overlaps the microstrip line; and

an external metal layer is disposed on a side of the first substrate away from the liquid crystal layer, the external metal layer being connected to a fixed potential.
