Metamaterial structures have found applications in antennas. In this paper a split ring resonator is analyzed for use in software defined radios and cognitive radios. A split ring resonator is designed and simulated in CST. The dimensions of the inner and outer ring are varied and tested in CST EM tool. It is been observed that the resonant frequency shifts to higher value with reduction in the inner ring size and total structure size. Meanwhile the SRR exhibits dual band resonance with large bandwidth. An array of two SRRs is also simulated. The results show dual bands, one at 5.66 GHz and other at 8.64 GHz. Such Metamaterial antenna finds applications in cognitive radios for free channel allocation from TV white spaces satellite microwave channel bands
