    FSS-Backed Reflectarray for Millimeter-Wave 5G Applications at the 28 GHz band
    (2023-06) Soroka, Roman; Martinez-de-Rioja, Eduardo; Arboleya, Ana; Encinar, José Antonio
    This contribution presents the design of a 30x30-element reflectarray antenna backed by a frequency selective surface (FSS) for millimeter-wave 5G applications at the 28 GHz band. 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.
