Abstract
A frequency tunable antenna includes a first substrate and a second substrate that are disposed opposite to each other, a second electrode disposed on a side of the second substrate close to the first substrate, a first electrode disposed on a side of the first substrate close to the second substrate, and a liquid crystal layer disposed between the second electrode and the first electrode. The second electrode and the first electrode are configured to adjust transmitting and receiving frequencies of the frequency tunable antenna by controlling an alignment manner of liquid crystals of the liquid crystal layer.
