Abstract—A novel Metamaterial Absorber (MA) based on rectangular shaped resonators with slot has been proposed in this paper. This metamaterial unit cell absorber possesses a nearly wide angle perfect absorption of incidence wave andpolarization independence. The absorption is occurred in GSM and DCS frequencies bands. The absorptivity is as high as 99% at around 0.9 (GHz) and 1.8 (GHz) frequencies. An important feature of this method is using a slot in the outer loop to simply tuning the resonant frequencies of this absorber. The proposed absorber represents a good absorption for different angle of incident.
