Abstract :
A new combined fractal geometry based Monopole antenna design for ultra wideband (UWB) applications is presented in this paper. This fractal structure is implemented on square and Minkowski fractal is applied to the lines of a square. Then, a Sierpinski carpet fractal is formed on the first iteration of the Minkowski fractal. The proposed antenna is miniaturized (45 mm × 45 mm) and has multi-band characteristics. Simulation results show that the presented antenna has a reflection coefficient characteristic <; -15dB, 80% radiation efficiency, 4-6dBi antenna gain and omni-directional radiation pattern properties over the UWB bandwidth (3.1 - 10.6 GHz). The gain variation is due to increased directivity at higher frequencies.
