In this paper, we investigate the potential of using double negative metamaterials to achieve a tri-band operation of microstrip antenna. We have shown that the three resonant frequencies of the microstrip antenna are not limited to integer multiples of the fundamental mode that operate at different harmonics. By choosing double negative metamaterials with different dispersion properties, the desired resonant frequencies can be achieved. Our proposed structure can produce two different radiation patterns at same time.
