Claim 17:
18. A method for fabricating a liquid crystal antenna, comprising:
providing a first substrate and forming a first conductive layer on a side of the first substrate, wherein forming the first conductive layer includes forming a plurality of driving electrodes in the first conductive layer;
providing a second substrate and forming a second conductive layer on a side of the second substrate, wherein the second conductive layer at least includes a plurality of radiation electrodes of block shape, 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 driving electrode on the second substrate at least partially overlaps the microstrip line;

pairing the first substrate with the second substrate, and disposing a liquid crystal layer between the first substrate and the second substrate, wherein the first conductive layer is disposed opposite to the second conductive layer; and
disposing an external metal layer on a side of the first substrate facing away from the liquid crystal layer to cause the external metal layer to be connected with a fixed potential.
