Abstract
ABSTRACT In this paper, an integrated low-profile frequency selective surface (FSS) is proposed, which has an ultra-wide absorption band in low band and a low loss transmission in passband. It consists of a bandpass metasurface (MS) and an absorptive MS loaded with resistors. Through coupling of the two metasurfaces, the perfect absorption in UWB is realized. Also, the equivalent circuit model of integrated FSS is deduced and its impedance is calculated. Furthermore, the mechanism of UWB absorption is provided. In addition, the integrated FSS with a central symmetrical unit is polarization-independent. The experimental results show that the absorptivity of the integrated FSS is larger than 89.8% in the range of 4–8.7 GHz except for some frequency points. The insertion loss at 12.64 GHz is only 0.4 dB. The experimental results are in good agreement with the simulation ones.
