The content discusses the development of a wearable millimeter-wave antenna for enhancing interaction with virtual reality (VR) devices. The key points are:
Current VR devices use inconvenient controllers or cameras that perform poorly in dark environments, disrupting immersive interaction. The authors propose utilizing RF-based approaches, such as millimeter-wave technology, to achieve non-intrusive and seamless VR interaction.
The wearable antenna operates in the 24GHz ISM band and is designed using polyester fabric, which has a lower loss tangent compared to other fabrics, to minimize dielectric losses. Additionally, a smooth coating is applied to the fabric to reduce losses due to rough surfaces.
The antenna features a low S11 value of -29dB at 24.15GHz, indicating good performance in the 24GHz ISM band (24GHz - 24.25GHz). The authors mention that the wide bandwidth of millimeter-wave technology enables simultaneous communication with multiple users and precise location detection, which is crucial for VR interaction.
The antenna is fabricated using conductive ink and a coating paper, which can minimize signal loss and protect the conductive layer from wear and tear. The production process involves printing the RF circuit on a coating paper and applying it to the polyester fabric.
The wearable antenna developed in this study opens up the possibility for more immersive interaction with VR devices, leveraging the advantages of millimeter-wave technology, such as high bandwidth and precise location detection, while addressing the challenges of fabric-based antennas.
