Abstract :
This paper discusses implementation of fractal elements into antenna technology. Purpose of that is design of fractal log-periodic antenna by means of computer program 4nec2 and operating in frequency range from 0.9 to 2.5 GHz and then this antenna is realized. Dimensions, radiation patterns, frequency dependence of Su parameter, input impedance Zin and gain G obtained by the simulation performed by 4nec2 and measured are compared in this thesis and they are similar. Characteristics, parameters and dimensions of LPA with fractal elements and LPA with common elements obtained by the simulation are compared as well.
