Creeping Wave on Body for VR Applications

Creeping wave on the body surface is critical to the cross-body communication when the Line-of-sight (LoS) path of the two antennas are blocked by the human body. This work focuses on the creeping wave in virtual reality (VR) on-body link. Link loss between head-mount display (HMD) and controller is tested for four antenna locations on head at 8 GHz with full body phantom. Moreover, four simplified phantom block shapes with two PIFA antenna are simulated at 2.4GHz to understand the impact from different bends.
