Frequency Reconfigurable Fractal CPW-Fed Antennas Designed for Telecommunication Applications

A frequency reconfigurable fractal antenna for wireless communication application is presented in this paper. Three RF switches are incorporated into the antenna design to achieve frequency reconfigurability. The proposed antenna is designed and simulated using the HFSS code and then fabricated. The experimental results confirm the numerical simulation and demonstrate that integrating the RF switches improves the antenna flexibility and enables us to switch the antenna from single-band to dual-band as well as to a multi-band state with minimal design complexity and high degree of miniaturization.
