Dual-Band Electromagnetic Skin With Independent Reflection Performance at 28 GHz and 39 GHz for 5G Millimeter-Wave Communications

Year: 2024

Type: article

Abstract: This letter presents a dual-band Smart Electromagnetic Skin (SES) for millimeter-wave 5G applications, which provides simultaneous operation at the 28/39-GHz bands with independent reflection performance at each band (i.e., different incidence and reflection angles). The SES consists of a two-layer reflectarray panel of 202.5-mm side, which produces two independent reflected beams in dual-polarization when it is illuminated from two different feeders (one for each operating band). A prototype of the SES has been fabricated and tested, and the measured radiation patterns agree well with the simulations. The 2-dB gain bandwidth exceeds 14.3% at 28 GHz (26-30 GHz) and 5% at 39 GHz (38-40 GHz). The dual-band SES will contribute to enhance 5G communications by producing two independent reflected beams when it is illuminated from two faraway base stations, each operating at a different frequency.
