A novel printed circular monopole antenna with bandwidth more than ultra- wide band along with reconfigurable single, dual and triple notch band is presented. The antenna provides bandwidth of 3.04 – 17.2 GHz by generating additional resonances towards higher end with modified ground structure. Moreover, the reconfigurable notches at WiMAX, WLAN and downlink of X band satellite communication are designed using slot technique to reduce interference at these wireless services if present. Thus, designed antenna provides a good solution for spectrum sensing and dynamic spectrum access as required in cognitive radios. The reconfiguration of notch bands is experimented using 0 ohm surface mounted resistors to show RF switching.
