Abstract
A holographic antenna, a beam control method, an electronic device and a computer readable medium are provided. The holographic antenna includes: a dielectric substrate including a first and second surfaces, a radiation layer on the first surface, a reference electrode layer on the second surface and switching units. Slit openings are in the radiation layer and in a one-to-one correspondence with the switching units. The holographic antenna further includes: a calculation part configured to obtain an excitation amplitude of each slit opening through an amplitude sampling function according to position information, a target pointing angle and a simulation frequency of the slit opening; a processing part configured to discretize the excitation amplitude of the slit opening to obtain a discretization result; and a control part configured to control a switching state of a corresponding switching unit according to the discretization result, to control the switching state of the slit opening.
