Abstract: An antenna assembly includes a lens, a guide rail, an antenna array, and a phase shifter. The lens has a first refractive surface. The guide rail is a linear guide rail and is located on one side of the first refractive surface of the lens. The antenna array includes a plurality of radiating elements. The antenna array is slidingly connected to the guide rail. As the antenna array moves on the guide rail, a beam pointing direction of the antenna assembly moves in an extension direction of the guide rail, to perform mechanical beam sweeping within a first sweeping range in the extension direction of the guide rail. The phase shifter is connected to the plurality of radiating elements and is configured to adjust feed phases of the plurality of radiating elements, to perform phase modulation sweeping within a second sweeping range.
