Polarization Insensitive Wideband Absorber for S- and C-band Application
In this, a wideband metamaterial absorber for Sand C-band application has been designed. The proposed absorber consists of lumped resistors loaded on Jerusalem cross shaped structure on the upper side of the metal film, which is separated by air spacer on the opposite side of substrate. The complete thickness of the designed absorber is $0.07\lambda_{0}$, where $\lambda_{0}$ is the lowest absorption frequency. Simulated results exhibited greater than 90% absorptivity in the frequency band from 1.95 - 5.73 GHz with an absorption bandwidth of 98%. The wideband absorption mechanism of the absorber analysed through the e characteristics.
