A compact optically controlled ultra-wideband (UWB) antenna with reconfigurable band-notched characteristics is investigated for cognitive radio (CR) applications. The rejection mechanism is realised by etching one symmetric folded slot on the U-shaped radiation patch and the essence of the reconfigurable function is achieved by laser controlling photoconductive switches to change the effective length of the folded slot. A prototype with an overall size of 25 × 25 × 0.8 mm3 is designed and…
