Abstract:In this paper, the development and designing of angle-independent metamaterial microwave absorbers are presented. The unit cell consists of two concentric circle that are linked by consolidated resistors. The absorber is built on a dielectric substrate (FR4) with a thickness of 3.2 mm (λ/0.07) and a dielectric constant of 4.3. The wideband absorption is acquired in the range of 2.8 to 10.42 GHz with a wide band of 7.62 GHz with absorptivity above 90%. In the area of interest, a flat band is obtained, and to ex… Show more
