A novel frequency reconfigurable slot antenna is designed for cognitive radio system. In cognitive radio system the two antennas are required one is a wideband antenna and another is frequency reconfigurable antenna. In this paper, a frequency reconfigurable slot antenna is designed between the switchable frequency range i.e. 7.34-7.96GHz at eight different frequency band and capable to operate single frequency at a time. The proposed antenna has a microstrip patch and a slot etched out in a ground plane.
