Abstract

An antenna array for a liquid crystal display able to function without a phase shifter includes at least two antenna units, each with an antenna module and a controlling circuit. The antenna module is at the side of a first substrate, a grounding layer, a feeding portion, a second substrate, and a liquid crystal layer also being included as a stack. The grounding layer and the feeding portion are on sides of the second substrate. The controlling circuit controls rotation of liquid crystal molecules of the liquid crystal layer therein to change a dielectric constant between the grounding layer and the antenna. The operating frequency of each antenna unit is thereby changed and radiation beam or pattern of the antenna array is thereby adjusted.
