The developed unit cell is obtained by combining two letters-like patches printed on a grounded dielectric substrate. The developed operating band is achieved based on the superposition of the two-resonances generated by the two letters. The simulations are based on Rogers RT5880 (thickness of 1.575 mm, dielectric constant of epsilon r=2.2, loss tangent of tan delta=0.009) and FR-4 substrates (thickness of 1.2 mm dielectric constant of epsilon r=4.3, loss tangent of tan delta=0.02). The obtained results show a wide 10 dB absorption bandwidth in the frequency range between 18 GHz and 30 GHz with absorptivity close to 99% for normal and oblique incident up top to 30 degrees in the case of Rogers RT5880. An absorptivity rate of 96% is obtained for the cased of FR-4 because of high dielectric losses. The obtained results are reasonable compared to other studies in the literatures.eninfo:eu-repo/semantics/closedAccessmetamaterialswideband metamaterialsmicrowave energy harvesting5GUAVWireless NetworksConference Object10.1109/ICEEE52452.2021.94159412-s2.0-85106518927
