UWB antennas development on the basis of genetic algorithm (GA) and particle swarm optimization (PSO) algorithm is described in this paper. New Bug-antenna, consisted of two different diameters circles, spaced at some distance between them, is proposed for this purpose. Then the cost function is defined to be less than -15 dB in the UWB frequency band 3,1÷10,6 GHz. This condition is provided by changing the antenna different geometrical characteristics. As a result two modifications Bug1 and Bug2, that provide stable frequency characteristics within the band, mentioned above, and also small size, were developed. PSO uses less number of calculations and provides the operating frequency band wider, than GA, but in this case the antenna size is bigger.
