In this paper, a compact, broadband, planar array antenna with omnidirectional radiation in
horizontal plane is proposed for the 26 GHz fifth-generation (5G) broadcast applications …

A metasurface lens antenna fed by a planar 8× 8 dual polarized antenna array is proposed
and characterized for full-dimensional massive multiple-input multiple-output (MIMO) and …

We present a method for the mitigation of quantization lobes in single-bit reconfigurable
reflective surfaces (RRSs). Typically, RRSs are planar beamforming structures consisting of …

Metasurfaces, ultrathin two-dimensional version of metamaterials, have attracted
