Zusammenfassung:This application provides a liquid crystal metasurface antenna apparatus and a communication apparatus. The liquid crystal metasurface antenna apparatus includes a liquid crystal metasurface reflection plate and a feed source, where the liquid crystal metasurface reflection plate includes a plurality of liquid crystal antenna units; the liquid crystal antenna unit at least includes a plurality of oscillators and two layers of dielectric plates; the plurality of oscillators are disposed between the two layers of dielectric plates; the plurality of oscillators include a horizontal oscillator pair and/or a vertical oscillator pair; and each oscillator includes a left arm, a right arm, and a capacitor, the left arm and the right arm are connected through the capacitor, and a liquid crystal material is filled in a space enclosed by the left arm, the right arm, and the capacitor. By using a liquid crystal locally loaded architecture system, a characteristic of beam scanning can be implemented, and a loss of a liquid crystal antenna can also be reduced. In addition, polarization reconstruction can further be implemented, and an operating bandwidth of an antenna is improved.
