Cognitive radio paper presents a switchable dual-band frequency reconfigurable antenna feed by microstrip feedline used for cognitive radio (CR) application. The proposed antenna consist of circular patch having the defected ground that gives the UWB band and used as a sensing antenna. Further C-slot is created at the circular patch and attaching a rectangular patch having a shape like L to the ciracular patch. Two parasitic rectangular surface is inserted at the ground plane. In between the two parasitic ground a SW is inserted to reconfigure the different bands. The length, width and thickness of antenna is 30mm, 30mm and 1.6mm respectively. The designed antenna provides a tuning range in 2.8-3.4GHz and S.36-S.94GHz. Simulated result provides the different reconfigurable bands used for WiMax and WLAN application. All results are simulated using the HFSS v.13.
