  The VR industry is one of the most promising industries for the near future,
as it can provide a more immersive connection between people and the virtual
world. Currently, VR devices interact with people using inconvenient
controllers or cameras that perform poorly in dark environments. Interaction
through millimeter-wave wearable devices has the potential to conveniently
track human behavior regardless of the lighting conditions. In this study, a
millimeter-wave wearable antenna was developed, opening up the possibility for
more immersive interaction with VR devices. The antenna features a low loss
tangent polyester fabric to minimize dielectric losses and a smooth coating to
reduce losses due to rough surfaces. The antenna operates in the 24GHz ISM
band, with an S11 value of -29dB at 24.15GHz.
