Abstract
A phased-array antenna and a multi-face array antenna device are provided. The phased-array antenna includes a liquid crystal cell. The liquid crystal cell includes an upper substrate, a lower substrate and a liquid crystal layer. The upper substrate includes a first base substrate, a plurality of first bias electrodes arranged at a first surface of the first base substrate, and a plurality of radiating elements arranged at a second surface of the first base substrate. The lower substrate includes a second base substrate, a plurality of second bias electrodes arranged at a second surface of the second base substrate, and a ground electrode arranged at a first surface of the second base substrate. The first base substrate and the second base substrate of the liquid crystal cell are arc-shaped substrates so that the radiating elements are not coplanar. In addition, the radiating elements are arranged at a convex surface.
