Design of 2.4GHz Patch Antenna with Rectangular Slot for WLAN Application Using SIW Technique

In this paper we implemented a 2.4 GHz patch antennae, which is used for applications of WLAN. For implementation of this antenna we need SIW technique. WLAN is generally used for wireless signal connection with limited range. In this paper we used FR-4 substrate having epsilon value 4.4 for implementation of patch antenna and its dimensions are 41.2 mm x 41.2 mm. The patch dimensions are 29.2mm x 29.2mm. This patch antenna covers only 2.4 GHz frequency range with the -23.801 dB return loss and this is best implementation of patch antenna for application of WLAN. The simulation has been done using CST with great performance.
