Experimental investigation of several novel fractal antennas-variants of the Sierpinski Gasket and introducing fractal FSS screens

Three novel methods of improving the impedance bandwidth at each of the multiple bands of the Sierpinski Gasket are proposed. The first and second method involve compensating and applying the self-complementary principle to the Sierpinski Gasket respectively. Wave scattering from fractal frequency selective surfaces, to create additional frequency bands of considerable bandwidth, is proposed as the third method. The measured results for these antennas show significant bandwidths ranging from 18 to 80% while maintaining the self-affinity and multiband behavior of the antenna
