An Optically Transparent Mesh-Antenna Integrated in OLEDs for WLAN Applications

This article discusses an original contribution to increase the optical transparency of the Transparent Conducting Oxides (TCOs) and to design optically transparent and invisible antennas that can be integrated in OLEDs light source. To validate the proposed technique, the meshed antenna is compared with the full metal antenna in terms of electrical, optical and radiation parameters. The proposed antennas are designed by using the ITO (Indium Tin Oxide) films printed on a glass substrate. The two antennas cover the 5.5 GHz band for WLAN applications. The peak gain of full-ITO and meshed-ITO transparent antennas are 4.41 dB and 4.33 dB at 5.52 GHz and 5.47 GHz, respectively. Due to increasing sheet resistivity, the gain of the meshed-ITO antenna are lower than the full-ITO antenna.
