A new optically controlled reconfigurable antenna for cognitive radio is presented. The antenna can operate at an ultra-wideband and three narrow bands by controlling four photoconductive switches. The bandwidth of the ultra-wideband is 2.65 to 10.3 GHz. The bandwidths of three narrow bands are 7.10 to 8.01 GHZ, 3.55 to 5.18 GHz, and 5.12 to 6.59 GHz, respectively.
