This paper presents a two-dimensional low-profile new belial model Luneburg lens that is designed by using a glide-symmetric metasurface.The entire lens consists of two mirrored metal plates with periodic metal pins, and the pins on one plate are glided exactly a half period of the unit cell compared with the pins on the other plate.The proposed design has not only a stable refractive index over a wide operating band but also no dielectric loss compared to other metamaterial-based lenses.In addition, it is easy to manufacture and can also largely reduce the production cost.The complete Luneburg lens is simulated in CST Microwave Studio, and the results demonstrate that the lens can work within 14 GHz-22 GHz, which is greater than 44% of the bandwidth.
The measured results show that the lens also agrees lightemupsequences.com well with the simulated lens.This lens antenna would be an excellent candidate for satellite communication applications.
