Cognitive Radio (CR) platform represents a technology resolution to increasing spectrum capacity and utilization. The conventional microstrip antennas lag in low gain and narrow bandwidth and it is the one of the major limitations .The most recent design for practical CR platform and wireless application is reduction in size with improvement in gain, bandwidth and multiple frequency operation. The challenging part was to develop metamaterial primarily based signature structures and techniques that overcomes the limitation of the conventional antenna by increasing the gain, bandwidth and applicable for multiple frequency operation. This paper proposes a Metamaterial inspired ultra wide band notched reconfigurable MIMO antenna for cognitive radio platform and Wireless applications. The projected antenna consists of two split ring resonators metamaterial antenna with reconfigurability. The split ring resonator used in this structure increase the wide band characteristics. By introducing a single switch at each gap of metamaterial structure, their impact can be activated and deactivated which ends in reconfigurable antenna. The projected antenna has better results of S-Parameters for ultra wide band (UWB), band notched operation, frequency reconfigurability and simulated using High Frequency Structure Simulator machine software package..
