A Hybrid Frequency Selective Absorber With Dual-Polarized Wireless Communication and Ultra-Wideband Absorption

Year: 2024

Type: article

Abstract: Traditional multi-layer frequency selective absorbers (FSAs) with antenna circuit suffer from inter-layer interference, which can adversely affect the in-band frequency bandwidth of wireless communication (fractional bandwidth FBW$0.22\lambda _{0}$. Simulated and measured results demonstrate the in-band FBW of 65.06% for wireless communication (2.8–5.5 GHz which is much wider than those reported FSAs with antenna circuit, e.g., FBW<20%) for two polarizations, with isolation less than −15 dB. Furthermore, the structure achieves impressive absorption performance, with radar cross-section reduction (RCSR) of 10 dB from 2.8 to 23 GHz (FBW=156.6%), and stable basic RCSR up to an oblique incidence of 30°.
