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.

Fine‐tuning snowflake fractal antennas
International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 2017 AbstractWe present a simple yet effective approach for fine‐tuning operating frequencies of snowflake fractal antennas. Given a basic design, a set of numerical simulations involving alternative corner angles are carried out to compute their isolated effects on frequency bands.
