Entropy and Fractal Antennas [PDF]
Entropy, 2016 The entropies of Shannon, Rényi and Kolmogorov are analyzed and compared together with their main properties. The entropy of some particular antennas with a pre-fractal shape, also called fractal antennas, is studied. In particular, their entropy is linked with the fractal geometrical shape and the physical performance.

Fractal Antennas: An Historical Perspective
Fractal and Fractional, 2020 Fractal geometry has been proven to be useful in several disciplines. In the field of antenna engineering, fractal geometry is useful to design small and multiband antenna and arrays, and high-directive elements.

Comments on DNA as a fractal antenna [PDF]
International Journal of Radiation Biology, 2011 Blank and Goodman (2011) proposed in this journal that DNA acts as a ‘fractal antenna’. “Since DNA can interact with EMF [electromagnetic fields] over a wide range of frequencies and does not appea...
