Abstract : The unaltered material existing in nature, fundamentally possess positive permeability and positive permittivity. In 1968, Veselago predicted the properties of a man-made material called as metamaterial which possess negative permittivity and/or negative permeability. Metamaterial are the composite structure of periodically arranged split ring resonators (SRRS) and wires having negative ratio (NRI). Research are verified the different metamaterial characteristics of various structured resonators like square, circular, rectangular, square split ring, MSRR,LR,SR, fractal E shaped MTM etc with their performances. Metamaterial split ring resonators are wont to load the microstrip patch antennas to scale back the scale and to boost the gain and bandwidth.
