Abstract

A high gain two elements inverted-L antenna (ILA) capable of generating two bands for 2.3 GHz mobile worldwide interoperability for microwave access (mobile WiMAX) and 5.5 GHz wireless-fidelity (Wi-Fi) operation is presented in this research. Geometry parameters of the antenna are optimized for 50 Ω antenna input impedance using method of moments (MoM's) in super-numerical electromagnetic code (super-NEC). The antenna occupies a small area of 60×80 mm 2 on a portable circuit board (PCB) and has 10-dB return loss bandwidth (BW) of 250 MHz (2180-2430 MHz) for 2.3 GHz (mobile WiMAX) band and 310 MHz (5320-5630 MHz) for 5.5 GHz (Wi-Fi) band making it easily cover the required bandwidths for mentioned applications. The simulated and measured return loss, radiation patterns, voltage standing wave ratio (VSWR) of the antenna shows good agreement and simulated radiation efficiency indicates the suitability of the antenna for the mobile WiMAX and Wi-Fi operation. The peak antenna gains of 4.75 dBi at 2.3 GHz and 8.65 dBi at 5.5 GHz are measured.
