Abstract :
A novel double negative(DNG)structure is proposed and a patch antenna using it as substrate based on the back wave(BW) theory is simulated in the paper. The result of the simulation shows the relative bandwidth of the DNG is wider than existing structures. It also shows that the novel structure has a very small electrical dimension and suitable for the substrate of patch antenna. By using this substrate, the size of the patch antenna can be reduced obviously.
