Abstract

A survey of microstrip antenna is presented, with emphasis on theoretical and simulation design techniques. Among several simulation techniques, Numerical Electromagnetic Code-2 (4NEC2) software is used by means of analyzing performance results. The wide band low profile modified Double Inverted-FL (DIFL) antenna covers 2.4 GHz for Wi-Fi, 5.2 GHz serving for WLAN, 2.5 GHz for WiMAX and also 2.1 GHz for UMTS applications. The antenna provides a total bandwidth of 850 MHz (2.0 GHz~2.85 GHz) which fully covers the 2.1/2.4/2.5 GHz bands and also 450 MHz (4.9 GHz~5.35 GHz) which covers 5.2 GHz band. The compact antenna is suitable in mobile phones and laptop computer for its small size, 31×21 mm². The antenna maintains a return loss more than -10 dB throughout the bands. The measured results also demonstrate that the proposed antenna has good omnidirectional radiation patterns with appreciable gain across the operating bands and is capable to implant within different portable devices for WiMAX/WLAN applications.
