The invention provides an electromagnetic wave lens. An outline shape of a cross section of a wave beam passing through the lens is similar to a rectangle or a square so that blind-area-free signal coverage can be realized by using the least lens antennas. A kernel body and a plurality of dielectric layers wrapping the kernel body are included. A dielectric constant of the kernel body is 1.7-2.3,the dielectric constant of the dielectric layer on the outermost layer is 1-1.2, and the dielectric constants of all the layers are smaller and smaller from the kernel body to the dielectric layer onthe outermost layer. Especially, the kernel body is a cuboid, and an appearance of each dielectric layer is also a cuboid. In fact, debugging personnel can complete debugging work of ground coverage more simply and accurately under a condition of avoiding large-area overlapping of different wave beams. The invention also provides an antenna adopting the electromagnetic wave lens and an electromagnetic wave lens antenna arr
