The proposed FSS-backed reflectarray works identically to a conventional metal-backed reflectarray in the 28 GHz band, where it can be used to enhance millimeter-wave coverage. However, in other bands of 5G, such as sub-6 GHz and 39 GHz, the antenna behaves as a transparent structure, suppressing the specular reflections of impinging signals.enginfo:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/closedAccess
