This paper investigates an ultrathin, single-layer and low-profile wideband absorber based on resistively-loaded high impedance surfaces for low millimeter wave frequency range. The proposed design features a dipole-like resonator incorporating a core component of resistive ohmic sheet. The absorber exhibits remarkable absorption characteristics, achieving an absorption bandwidth spanning from 18 to 40 GHz, maintaining an average absorption rate exceeding 90 %. Moreover, an analytical model based on RLC components for the designed absorber has been developed to verify the precision of the simulation results.

Abstract
This paper investigates an ultrathin, single-layer and low-profile wideband absorber based on resistively-loaded high impedance surfaces for low millimeter wave frequency range. The proposed design features a dipole-like resonator incorporating a core component of resistive ohmic sheet. The absorber exhibits remarkable absorption characteristics, achieving an absorption bandwidth spanning from 18 to 40 GHz, maintaining an average absorption rate exceeding 90 %. Moreover, an analytical model based on RLC components for the designed absorber has been developed to verify the precision of the simulation results.File in questo prodotto:
