(EN) The invention discloses a dielectric cylindrical lens, a dielectric film and a manufacturing method of the dielectric cylindrical lens, and solves the problems that an existing antenna is poor in parameter consistency, large in scattering and large in bidirectional communication interference. The dielectric cylindrical lens is a cylinder formed by concentrically surrounding a dielectric material;the dielectric material comprises a dielectric film, and the dielectric film is prepared by mixing ceramic powder into a cellulose dissolving solution or paper pulp. The dielectric cylindrical lens manufacturing method comprises the steps: taking a preset dielectric constant of each layer of a dielectric lens as a target equivalent dielectric constant of a composite layer structure; adjusting thedosage of the ceramic powder to prepare a dielectric film or composite layer structure conforming to the target equivalent dielectric constant; and concentrically winding the dielectric film or the composite layer structure into a cylinder. According to the invention, the cylindrical lens with stably distributed dielectric constants is realized.
