Abstract

In this paper a wire type low-profile impedance matched wideband double inverted-F (DIFA) antenna for WiMAX/Wi-Fi operations in a laptop computer is presented by means of numerical simulations. The antenna has a compact size of 920 mm2 and provides a wider bandwidth of 2.5 GHz (50507550 MHz) which fully covers the 5.5 GHz operating band. Moreover it has very high peak gain of 7.0 dBi with less than 1.5 dBi gain variation within the 5.5 GHz operating band. In application of matching network, the input impedance of the antenna well matched to the antenna feeding, also improvement in return loss and voltage standing wave ratio (VSWR) is achieved. In addition the antenna has good return loss and radiation characteristics.
