Flexible CPW Fed Antenna with Organic Substrate for WLAN Applications

This paper introduces a flexible CPW fed antenna comprising conductive fabric on organic Basalt fiber composite substrate and is designed to be compatible with 2.4 GHz and 5 GHz wireless local area network (WLAN) systems. High flexibility of this antenna contributes by the ungrounded CPW fed which reduced the overall thickness and also the flexible thin layers of 0.17 mm radiating element and 0.42 mm substrate. This antenna has compact size of 49.90 mm x 51.15 mm and composed of a C shaped strip and spiral strip which enables the antenna to work at 2.05 GHz - 2.87 GHz and 4.07 GHz - 6 GHz band respectively. The simulation results proved the satisfactory gain and radiation pattern of the flat antenna and the antenna in different bending curvature using the CST Microwave Studio Simulation.
