Reflective Metasurface for 5G mmWave Coverage Enhancement

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.
