The unit cell is designed by combining two letters (H & S) and side patches for the generation of multi-resonance bands, and printed on a grounded dielectric of Rogers RT5880 material. Based on the numerical plane-wave simulations, the proposed absorber exhibits an ultra-wideband of about 16.2 GHz absorption bandwidth in the frequency range between 27.669 GHz and 43.871 GHz. The average absorptivity rates are close to 99% for incident angles between 0°-20°. The developed absorber preserves the ultra-wideband property of about 11.50 GHz for incident angles between 20° and 30° in the frequency range between 27.7 GHz and 39.2 GHz with average absorptivity rates close to 90%. This design is very suitable for 5G millimeter-waves and Ka-band applications. © 2022 IEEE.eninfo:eu-repo/semantics/closedAccess5gElectromagnetic interference reductionEnergy harvestingMetamaterials (MM)Millimeter-wave(mm-wave)ShieldingUltra-wideband METAMATERIALS5G mobile communication systemsElectromagnetic pulseElectromagnetic shieldingElectromagnetic wave interferenceMetamaterialsMillimeter wavesSignal interferenceUltra-wideband (UWB)5gAbsorptivitiesElectromagnetic interference reductionsFrequency rangesIncident anglesMetamaterialMillimeter-wave applicationsPerfect absorberUltra-wideband METAMATERIALSUltrawide bandEnergy harvestingConference Object10.1109/ICEEE55327.2022.97725472-s2.0-85130952519
