In this research article designing of a multiband antenna and simulation result of the same is presented. Initially a rectangular microstrip antenna was designed and then bandwidth and other parameters along with its operating bands were modified using the modification technique which is widely known as metamaterial. Designed antenna was radiating at 2.32GHz frequency with -10dB return loss and bandwidth was very nominal i.e. 17MHz only. Later after keen literature review it was found that various techniques are available to modify such low-quality antennas. Metamaterial technique was found more superior along with the other available techniques. After implementing metamaterial parameters drastically modified, single band antenna converted into 4 bands with bandwidth of each band was greater than previous one.
