Abstract
—A wide-incident angle and polarisation insensitive transparent metasurface is presented for 5G outdoor to indoor coverage enhancement. In order to predict the structural geometry of the unit cell, the Genetic Algorithm (GA) has been applied. The proposed unit cell is arranged in a periodic structure to construct the transmission surface consisting of tow transparent layers of Indium Tin Oxide (ITO) mounted on both sides of Polyethylene Terephthalate (PET) substrate. The proposed transmission metasurface can be simply coated on a glassy windows to empower the outdoor to indoor 5G signals.
