Abstract

A metasurface-based thin flat lens operating at millimeter wave frequencies is presented. The three-layered Huygen Metalens indicates collimating/focusing of broadband frequencies from 60 to 74 GHz, with a gain enhancement of 22.5 dBi at a central frequency of 69 GHz while fed by a dipole antenna. The metasurface transmission performance is designed and simulated by numerical and analytical approaches. By integrating multilayered Huygens unit cell, the metasurface produced 1800 phase coverage with constant high amplitude. The proposed design comprised of 50×50 unilcells, creating an area of 75 × 75mm2. The dipole antenna is applied to illuminate the proposed metasurface where the distance between the feeder and metalens is 27 mm. The result shows that the proposed metalens antenna achieves a maximum gain of 25 dBi at 69GHz GHz. The unique features of the proposed light-weight metasurface will be easily implemented for flat transceivers for 5G and future 6G millimeterwave communication, detection, and imaging applications.
