This paper presents a design of dual-polarized broad-beam reflective metasurface (MS) for 5G mmWave application at 28 GHz. Its broad-beam operation is simply realized by combining multiple MS sections with having different diffraction grating periods

In order to simply broaden reflection beam of metasurface, the utilization concept of multi-sheet configuration is presented and investigated. Demonstration is based on four sheets of 28.25 GHz metasurface that have the same designed incident angle.

To solve the problem of shadow area in wireless network, a metasurface is expected to anomalously reflect the wave from base station to user in non-line-of-sight (NLOS) area. However, the sensitivity between an incident and reflection angles makes mo
