In this letter, the Koch iteration technique has been applied to obtain two fractal versions of a folded-slot antenna. A simple folded-slot antenna, first iteration and second iteration versions of a Koch folded-slot antenna were designed, fabricated and characterized on a 30 mil thick RT/Duroid 6002 substrate. The simple folded-slot antenna provides a return loss of 40 dB at the operating frequency of 10.45 GHz and the bandwidth for return loss greater than 10 dB is 1.211 GHz. The return loss of the first iteration of the Koch folded-slot antenna is 34 dB at 8.05 GHz and the bandwidth for 10 dB return loss is 0.4 GHz. The return loss of the second iteration of the Koch folded-slot antenna is 42 dB at 7.9 GHz and the bandwidth for 10 dB return loss is 0.34 GHz
