A new design for metamaterial absorber with triple band in X band range is proposed for Radar cross section reduction in stealth technology. The proposed metamaterial absorber has the advantage of ease design. It is a three layered structure, designed with modified ring resonators printed on a dielectric material with a metal ground. By proper tuning of the geometry parameters of the structure, a triple band metamaterial absorber is achieved and it is adjusted to match the effective impedance of metamaterial absorber to the free space. Hence, there is no wave transmission, minimized reflection and the absorption rate is maximized in all the bands. The resonant frequency bands are at 7.7 GHz, 9.2 GHz and 11.1 GHz with absorption rates of 99.7%, 98% and 94% respectively. The bandwidths measured at the triple band are 0.2757 GHz, 0.311 GHz and 0.2182 GHz. The total miniaturized metamaterial absorber unit cell size is 6 mm × 12 mm × 0.705 mm. Simulation results show that the proposed absorber with triple band and with high absorption rate is well suited for Radar cross section reduction in stealth technology.read more
