A High Isolation Dual-Linearly Polarized Ultra Thin Transparent Patch Antenna with Metal Mesh for Wearable Glasses

In this paper, a high isolation dual-linearly polarized transparent patch antenna with metal mesh is designed at 60 GHz. A single meshed patch element is excited by direct feeding for vertical polarization, and slot-coupling feeding for horizontal polarization. The simulation results demonstrate that the proposed antenna has a good TX/RX isolation, which reaches 43 dB @ 60.1 GHz, and the realized gains for both TX and RX ports are up to 7.3/7 dBi @ 60 GHz. Owing to the merits of high transparency and ultra thin characteristics of the applied printed metal grid transparent conductive film, the proposed transparent antenna could be integrated on wearable glasses without blocking sight, and provides hardware equipment foundation for the application of drivers' fatigue detection in radar sensing.
