Abstract
A liquid crystal antenna is provided. The liquid crystal antenna includes a first substrate, a second substrate, a liquid crystal layer, a plurality of transmission electrodes including a first transmission electrode and a second transmission electrode, a plurality of signal lines including a first signal line and a second signal line, a plurality of signal terminals including a first signal terminal and a second signal terminal, and a ground electrode. A transmission electrode is electrically connected to a signal terminal through at least one signal line. The first transmission electrode is connected to the first signal terminal through the first signal line, and the second transmission electrode is connected to the second signal terminal through the second signal line. A resistance of the first signal line is A, and a resistance of the second signal line is B, where A/B is less than 10.
