Attenuation of Building Materials and Structures in 5G Millimeter Wave Band

Material attenuation in the frequency band from 26 to 40 GHz was measured. Attenuation of building materials as bricks, concrete blocks, and plasterboard, as well as attenuation of glass and artificial materials used for cladding and plating is measured and presented. Furthermore, attenuation of a window with single-chamber insulated glazing unit and aluminum Venetian blinds is given. Finally, attenuation of books and magazines was also investigated. It was found that attenuation introduced by many common materials found in buildings can seriously affect signals in 5G frequency range 2 (FR2).
