Abstract: A liquid-crystal antenna apparatus is provided. The liquid-crystal antenna apparatus includes: a liquid-crystal antenna unit and a control unit. The liquid-crystal antenna unit is configured to receive a wireless signal. The liquid-crystal antenna unit includes a plurality of microwave elements, and each of the microwave elements includes a first electrode, a second electrode opposite to the first electrode, and a liquid-crystal cell disposed between the first electrode and the second electrode. The control unit is electrically connected to the liquid-crystal antenna unit, and is configured to control the liquid-crystal antenna unit to form a first beam having a first direction. The control unit determines a source orientation of the wireless signal according to the wireless signal received by the liquid-crystal antenna unit, and controls the first direction of the first beam to direct toward the source orientation.
