Dual-Polarized Dual-Band Antenna-on-Display Using Via-Less and Single-Layer Topology for mmWave Wireless Scenarios

In this letter, a dual-polarized dual-band antenna-on-display (AoD) is proposed for millimeter-wave (mmWave) wireless scenarios. The proposed AoD schematic supports patch and monopole mode based on a shared aperture and antenna feed network concept. The devised AoD exhibits dual resonance with <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$ - $</tex-math></inline-formula> 10 dB <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">S</i> <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</sub> bandwidth of 26–31 GHz (17.8%) and 33–40.5 GHz (19%). Based on the proposed unit element, a 1 × 4 phased array AoD is exemplified to verify its beam steering capability.

The proposed work is the first to realize multipolarized, multiband AoD under realistic conditions. This letter aims to suggest a principal example for future multiband mmWave wireless scenarios using display panel as antennas.
