Dual Band Two Elements Inverted-L Antenna for 3.5 & 5 Ghz Mobile Wimax/Wi-Fi Applications
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 x 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.
