Abstract

A Yagi-Uda antenna constructed of three Koch fractal elements is presented. Simulated and measured characteristics of the antenna shows a half-power beam-width of 64° achieved with dimensions below a third of a wavelength. Furthermore, the Koch dipole and its size miniaturization capabilities are investigated.
