Abstract :
In this paper the fractal method is used to realize two novel antennas useful for Ultra Wideband Radio. Fractals have self-similarity, which lends them to simple replication and desirable space filling for current path maximisation in a given footprint. Candidate fractal antennas considered here are a modified Minkowski fractal and a Koch-Square loop fractal. Both antennas are optimized to operate within the FCC UWB mask with a -10 dB of reflection loss. Reasonable gain and broadside directivity are also achieved. The antennas were synthesised with the Method of Moments package 4NEC2X.
