A Fractal Metamaterial Antenna for Bluetooth, WLAN, WiMAX and X-band Applications

A novel multiband fractal wide slot meta material antenna is designed for Bluetooth/WIMAX/WLAN and X band downlink applications. In order to generate the WLAN (2.4/5.8GHz) and X-band (7.5 GHz) spectrums, the antenna slot structure is now in the form of a new fractal-like geometry on the first iteration. The Bluetooth (2.45 GHz) and WIMAX (3.5 GHz) bands are excited when the antenna is loaded respectively by a loop resonator and meandered shaped meta materials. The proposed antenna was simulated using both (CST MWS) and (HFSS) to verify against the obtained simulation results. This antenna has successfully demonstrated multiband and broadband characteristics. Simulation results show that the antenna gives an acceptable antenna gains over the resonant frequency signals. In addition, influence dimensions on the electromagnetic performance for the meandered-shaped and resonator and fractal circular slot for this structure are performed and implemented in detail this paper.
