Abstract
AbstractAn ultra‐wideband metamaterial absorber (MA) is proposed for 5G communication, which features a resistive frequency selective surface printed on a PET (polyethylene terephthalate) layer and a ground layer of resistive film. The proposed MA can provide over 90% absorptivity in the frequency range of 11.2–42.8 GHz. Moreover, it is insensitive to polarization and wide incident angles. The effective medium theory and multi‐reflection interference theory are used to interpret the broadband absorption mechanism. The surface current distribution at three absorption peaks is investigated to further study the physical mechanism behind the wideband absorption. The measured results of the fabricated prototype are in good agreement with the simulation ones, thus verifying the robustness of the design. The presented MA can probably be used in electromagnetic shielding of 5G signals.
