A novel wearable metamaterial Fractal antenna for wireless applications

This paper proposes a novel multiband Wearable Fractal antenna which suitable for GPS, WiMax and WiFi (Bluetooth) applications in the same time. This antenna is designed to operate at four resonance frequencies are 1.57, 2.7, 3.4 and 5.3 GHz. The proposed wearable antenna may be attached to life jacket to aid for finding the human body if an accident happened so, the specific absorption ratio (SAR) must be calculated. Therefore anther designed to reduce the SAR value with a spiral metamaterial meandered in the ground plane is introduced. The specific absorption rate (SAR) investigation is carried out on CST2014 Simulator. Maximum SAR value is 0.925 W/Kg which indicates that the wearable antenna are safe for human. The proposed antenna was simulated by CST simulator version 2014 and fabricated by photolithography technique.
