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.The aim of this project is to model, simulate and fabricate a multiband slot antenna for various frequency bands to achieve enhanced VSWR, S11 parameters and uniform 3D radiation pattern.The dimensions of multiband slot antenna are calculated using general antenna parameter formulae.The layout of the antenna is simulated in an EM tool of Computer Simulation Testing (CST) and the antenna is fabricated using photolithographic process.
