Reflective Metasurface for 5G mmWave Coverage Enhancement

Abstract

The proposed intelligent reflective surface (IRS) is presented to compensate for the path loss and enhance the coverage of 5G networks at mm-wave band. A($\pi$) shaped element with variable-sized dipoles, distributed in a certain way to maintain a phase length curve over 340° in the range of 23–27 GHz, is addressed in this work. The proposed structure can be an ideal candidate for 5G mm-wave band n258.
