摘要

In this article, radiation beam deflection of a mm‐Wave antenna is presented using a metasurface (MTS). The beam tilting MTS consists of phase gradient resonators to transform an incoming wavefront to a tilted planar wavefront. The MTS is fed via gain enhanced dipole antenna having a tilted radiation beam. The gain of the dipole antenna is enhanced by printing a high refractive index surface in front of the radiator. The MTS is then loaded vertically in front of the gain enhanced dipole antenna using a 3D printed stand. The prototype antenna covers 27–30 GHz band with a tilted radiation beam. A beam tilt of 20° is achieved using the MTS with a peak gain of 10 dB over the frequency band.
