Abstract
Provided are a liquid crystal antenna and a preparation method of the liquid crystal antenna. The liquid crystal antenna includes a liquid crystal cell and the liquid crystal cell includes a first substrate, a second substrate, a microstrip line, a ground metal layer, a liquid crystal layer, and frame glue. The liquid crystal antenna further includes a third substrate, a fourth substrate, and a radiation electrode. The third substrate extends beyond an edge of the first substrate. The fourth substrate extends beyond edges of the second substrate on at least two sides. A connection structure is disposed between the third substrate and the fourth substrate, and the connection structure is disposed on an outer side of the frame glue. The liquid crystal antenna and the preparation method of the liquid crystal antenna are provided to reduce preparation difficulty and improve reliability.
