Antenna-on-Display (AoD) for Millimeter-wave 5G Mobile Devices

Abstract

This paper proposes a novel concept of an optically invisible antenna-on-display (AoD) realized using photolithography that can be integrated in active display panels such as OLEDs and LCDs. The proposed approach is exemplified for future millimeter-wave 5G mobile devices. A multi-layer structure with AoD is proposed and designed for potential beam-steering applications. The designed and fabricated 1×8 AoD exhibits 9.16 dBi boresight gain at 28 GHz while maintaining 88% optical transparency.
