Abstract
Fractal geometries have shown to be attractive for antenna designers because of the
unique features they offer. In this paper, a printed fractal based slot antenna has been introduced
to be used in multi-band wireless applications. The slot structure of the proposed antenna is of an
octagonal shape with a Koch fractal curve of the second iteration is applied on each of its sides.
The slot structure has been etched on the ground plane of a substrate with relative permittivity of
4.4 and 1.6mm thickness. On the reverse side of the substrate, a 50 ohm microstrip line feed has
been etched. To enhance the coupling with the slot, the feed line has been loaded with a circular
stub with embedded complementary circular split ring resonator. Based on the lowest resonant
frequency, it has been found that the largest dimension of the proposed antenna slot structure is
less than half the guided wavelength. Parametric study shows that the resulting antenna o®ers
a multi-band behavior with enhanced gain and fractional bandwidths, besides the reasonable
radiation characteristics throughout the resonating bands. With appropriate dimension scaling,
the proposed antenna could be a suitable candidate for use in a wide variety of multi functions
wireless applications.
