Abstract: An UWB antenna having two notch bands is proposed in this paper. This structure helps to improve the isolation characteristics and is used for Wi-max and WLAN applications. For enhancement of isolation here we used two split ring resonators on left and right of the feedline with the edge to edge spacing of 0.5. Further, some parameters like Envelope Correlation Coefficient (ECC), diversity with respect to gain, efficiency with respect to efficiency, peak gain and radiation patterns are discussed. Two pairs of split ring resonators act as a decoupling-elements which leads to the formation of two notch bands between 5GHz to 8GHz(C-Band), 10.4GHz to 10.7GHz (X-Band). A stable gain of 4.2dB and efficiency of 89% is maintained throughout the UWB region. The proposed design is stimulated using ANSYS electronic desktop 19 and prototype is fabricated using FR4 substrate on PCB prototype machine. The results obtained from the simulation tool and from the experimental setup are analyzed which shows that proposed MIMO diversity antenna is suitable for dual notched UWB applications.
