In this article, metamaterial based miniaturized DGS (Defective Ground Structure) antenna is presented. Initially conventional antenna is designed for 2.4 GHz and by using DGS method, the same conventional antenna size is reduced upto 50% of initial design. But antenna gain down due to DGS in antenna structure. By using metamaterial as a reflector, the antenna gain can be enhanced. The antenna and metamaterial are designed on Rogers RT5880 and Teflon Ceramic TF-1/2 (ε r = 10.2, tanδ = 0.001) respectively. All simulation results are carried out by using EM simulator CST software and for the operating frequency of 2.415 GHz a gain of 6.28dB is observed.
