摘要：

In this letter, a single-layer wideband absorber with compact thickness is proposed, and its ability to reduce the radar cross section (RCS) is investigated. The absorber consists of two-dimensional array of conductive crossed dipoles with lumped resistor elements on the top of a single-layer FR4 substrate, backed by continuous metallic layer. Simple methodologies for design and analysis of the absorber are presented. The thickness of the fabricated sample is less than 0.077 lambda(L) (wavelength at the lowest cutoff frequency). It offers the 10-dB reflection reduction bandwidth of 70.7% (5.3-11.2 GHz) and full width at half-maximum (FWHM) absorption bandwidth of 104.76% (3.75-12 GHz). The experimentally demonstrated performance of the absorber shows good agreement with the numerical simulations.
