Millimeter-wave Huygens' Metasurfaces based on All-dielectric Resonators for Antenna Beam-forming
A novel mm-wave all-dielectric structure based on Huygens' metasurfaces is proposed to engineer the radiation fields of a 2D slot array antenna, and demonstrated using full-wave simulations. The proposed metasurface consists of elliptically-shaped resonators whose geometrical dimensions can be engineered to enable rich wave transformation capabilities. They are placed on top of the slot antenna array in its near-field zone and designed to transform the intrinsic uniform field distribution of the antenna to desired radiation patterns. A beam-tilting example has been presented to demonstrate the proposed principle.
