The design of multiband slot antenna includes different services such as GPS, WiMAX and WLAN systems. The
inclusion of a ground slot in an antenna ground plane can be extended to include reconfigurable features. In this multiband
slot system is proposed to intend GPS, WLAN(over two frequency bands ),and WiMAX. The design of four band slot antenna for
the global positioning system, worldwide interoperability for microwave access and wireless local area network is presented. The
antenna consists of a rectangular slot with a T-Shaped feed patch, an inverted W-shaped stub and two C-shaped stub to generate
four frequency bands
