The invention discloses an antenna structure, an operating method therefor, and antenna equipment. The antenna structure comprises a first dielectric substrate; a first electrode layer and a second electrode layer which are disposed at one side of the first dielectric substrate and are arranged oppositely; a liquid crystal layer disposed between the first electrode layer and the second electrode layer, wherein the first electrode layer comprises a first electrode bar and a second electrode bar, which are insulated with each other. The first and second electrode bars can form a horizontal electric field, thereby enabling the orientation of liquid crystal molecules in the liquid crystal layer to tend to be the direction of the horizontal electric field. The radiation range of the antenna structure can enlarged without an additional orientation layer, the difficulty of the preparation technology of the antenna structure is reduced, and the cost is saved.
