This paper investigated the variations occurring in band width of the antenna when mushroom like structured meta-materials are used. Generally the operating frequency may vary according to the tuning of band of meta-material to the band of antenna. Here the tuning may vary according to via size or the gap between metal plates of the meta-materials. Here the analysis is done to verify the return loss and the band width variations according to the meta-materials placed. And the comparative analysis is produced for a simple monopole antenna and a patch antenna for various via lengths in meta-materials.
