Hybrid Fractal Antenna Using Meander and Minkowski Curves for Wireless Applications

This paper describes a novel design of Minkowski and Meander curves based hybrid fractal antenna for mobile devices used for communication in delay tolerant networks, wireless sensor networks and mobile adhoc networks. Meander curve improves the impedance bandwidth. Minkowski fractal curve gives its contribution to make antenna multiband. The proposed antenna resonates at five frequencies 1.98, 5.94, 10.61, 12.73, 14.85 GHz. Prior to fabrication, better performance parameters such as return loss, radiation pattern, gain, current distribution, impedance, VSWR are achieved. The maximum bandwidth 2.83 GHz and gain 9.0 dB at 2.4 GHz are achieved. The proposed antenna can be used for various applications like Bluetooth, Wi-Fi, Wi-Max, Wi-Bro, AWS, GPS, S-DMB, WLAN 802.11b/g and DTH services etc. Simulated and measured results are compared and are found in agreement with each other.
