The present invention provides a better electromagnetic lens, a method for producing it and a lens antenna. The electromagnetic lens is a winded body made of a strip material. The dielectric constant of a dielectric material gradually changes in both a transverse direction and a longitudinal direction of the strip material. After the strip material is winded to be a winded body, the dielectric material is distributed in at least one artificially predetermined three-dimensional space range called a lens body inside the winded body. A part of the winded body besides the lens body is called a non-lens part. The dielectric constant of the lens body is not lower than that the dielectric constant of the non-lens part.

The present disclosure provides a production method for a Luneburg lens, which can manufacture a Luneburg lens with stable indexes and high performance under the conditions of room temperature, normal pressure, and low cost. The production method includes the following steps: bonding first granular materials into a sphere by a bonding agent, so as to obtain a sphere core; spraying the bonding agent on the surface of the sphere core, placing the sphere core in a container containing second granular materials, and rolling the sphere core, so that the surface of the whole sphere core is bonded with the second granular materials until the thickness of the second granular particles reaches a preset range, and thus forming a dielectric layer coating the sphere core; and by analogy, preparing a predetermined number of dielectric layers, so as to obtain a target finished Luneburg lens.
