Abstract—A new small size fractal antenna is proposed for the
application in wide-band frequency range. It is designed with the
combinations of two fractal geometries. The wideband
mechanism is explored by investigating the behaviour of the
current on the patch. The length and width of Koch and cantor
fractal geometries are optimized to achieve a wide bandwidth.
The feed circuit is a microstrip line with a matching section over
a rectangular ground plane. The measured -10dB reflection
bandwidth for frequency range (1.64 GHz to 3.5 GHz) is
72.37%.The EM characteristics of the antenna are presented by
surface current distributions. The radiation characteristics and
