Novel, dual-band, single and double negative metamaterials composed of nonconcentric and different sized delta loop resonators are presented. The proposed structures provide two distinct resonant frequencies in the microwave region. Effective medium parameters of these metamaterial structures are extracted using retrieval method to demonstrate the presence of the mentioned frequencies. In addition, equivalent circuit model for the individual magnetic resonator and wire strip is presented to give a clear explanation for the resonance behavior of the structures and to validate the proposed designs. The results show that the proposed metamaterials can be used as an alternative to the known counterparts especially when a dual-band operation is needed at the frequency region of interest.
