Dual Band and Beam-Steering Antennas Using Reconfigurable Feed on Sierpinski Structure
International Journal of Antennas and Propagation, 2015 Fractal patch antennas based on the Sierpinski structure are studied in this paper. The antennas operate at dual bands (around 2 and 5 GHz) and are designed to steer the beam directions at around 5 GHz band (the first harmonic).

Electronics Letters, 1998 The fractal volume antenna concept is introduced in order to increase the degree of design freedom associated with fractal antenna elements and hence improve their input matching characteristics. Practical examples are given involving the Sierpinski triangular gasket monopole and a novel Sierpinski carpet gasket microstrip antenna.
