Flexible Textile Antenna Design with Transparent Conductive Fabric Integrated in OLED for WiMAX Wireless Communication Systems

A new flexible antenna made entirely from a transparent conductive fabric VeilShield has been designed to be integrated in OLED light sources as well as flexible or rollable displays. It was layered on a 100% polyester support with a thickness of 1.5 mm and achieves a good adaptation and high gain. The simple and flexible patch antenna has been designed to operate at two frequencies bands: the first one operating at 3.15 GHz in S-band and the second operating at 3.5 GHz for WiMAX wireless communication systems. We have evaluated and tested its performances, including the reflection coefficient, the gain, the radiation pattern and the surface current distribution, with gain values of 5.76 dB and 1.66 dB respectively. This article demonstrates the applicability of the material proposed for the design of flexible antennas integrated into OLED light sources while maintaining gain performance comparable to conventional planar antennas.
