Design and performance analysis of ultra wideband Inverted-F antenna for Wi-Fi, WiMAX, WLAN and military applications

In this manuscript a modified Inverted-F antenna (IFA) is designed to serve the purposes of mobile WiMAX, Wi-Fi, WLAN as well as military applications. The main intension of this work is to propose an ultra wideband antenna for multi-serving purposes with good return loss characteristics, high gain as well as impedance matched and good radiation characteristics. An ultra wideband antenna (modified double IFL antenna) is proposed which bandwidth is 2.16 GHz (3.34-5.5 GHz) serving for WiMAX (3.4-3.6 GHz), Wi-Fi (5.15-5.35 GHz), WLAN (5.15-5.35 GHz) and military (4.4-4.8 GHz) applications. The proposed antenna is of good gain and good radiation characteristics. As the dimension of the proposed antenna is very small, the antenna is promising to be embedded within the different portable devices employing Wi-Fi/ mobile WiMAX applications.
