A new meta-material based bowtie antenna is proposed in this paper. Multi band response is observed in the simulated result of return loss for different frequencies (i.e., 1-12GHz). Apart from this it is seen that the return loss is improved in the case of metamaterial antenna in comparison to the conventional antenna. Simulated results of ζ and μ versus frequency are shown and it is observed that negative ζ and negative μ are obtained in different frequency bands respectively.
