Abstract

In this article, an optically transparent antenna, integrated in organic light-emitting diodes (OLEDs), is proposed for sub-6 GHz 5G applications. The concept of the mesh geometry is applied to obtain high optical transparency. To validate this technique, the transparent antenna is compared with the non-transparent in terms of electrical, optical and radiation parameters. These antennas are designed on a transparent glass substrate with dimensions of 30 × 35 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and using copper films. The two antennas cover the 3.5 GHz band for 5G applications. The peak gain of the transparent antenna integrated in OLEDs light sources is 5.53 dB at 3.57 GHz. The gain value, improved after the integration, can be justified by the effect of OLEDs layers.
