Abstract
This paper presents the numerical simulations of dual band two elements Inverted-L antenna for 3.5 GHz mobile WiMAX and 5 GHz Wi-Fi operation. The proposed antenna is feed by a coaxial connector. The antenna arms effectively control the excited resonant modes for Wi-Fi and mobile WiMAX operation. Total area occupies by the antenna is 20 mm × 30 mm. The antenna contains substantial gain with less than 0.3 and 2 dBi gain variation within the -10 dB return loss bandwidth at 3.5 and 5 GHz operating frequency respectively. In addition, the antenna has achievable bandwidth, return loss and radiation characteristics for both frequencies. Due to the compact area occupied, the proposed antenna is promising to be embedded within the different portable devices employing 3.5 GHz mobile WiMAX and 5 GHz Wi-Fi operation .
