Abstract In this paper, a coplanar bandwidth-enhanced metamaterial absorber is presented based on the combination of three dual-band sub-cells. The simulated results show that the absorber is polarization insensitive and adaptive for wide angles of oblique incidence. The simulated FWHM absorption bandwidth is 1.09 GHz (6.04–7.13 GHz), with the relative FWHM absorption bandwidth of 16.6%. A sample is fabricated. The experimental results verified that FWHM absorption bandwidth is 1 GHz (6–7 GHz), with the relative FWHM absorption bandwidth of 15.4%, and the absorption peak of 77.5% is obtained.
