Optically reconfigurable Sierpinski fractal antennas for RoF based communication systems

In this paper, the frequency reconfigurability of the Sierpinski fractal antenna is studied by using doped silicon optical switches. Selecting the optical switches as a reconfiguration tool makes the antenna more suitable for radio over fiber based communication systems since the necessary optical tools have already been settled for communication. Findings prove the multiband reconfigurability property of the proposed antenna which is an important issue for the emerging communication standards such as cognitive radio.
