Analysis of the Body Proximity Cross-Polarization Power Ratio in a human walking motion

This paper presents a preliminary investigation on the body proximity cross-polarization properties considering the human walking motions for BAN on-body wireless communication systems. A novel concept of the BP-XPR (Body Proximity Cross-Polarization Power Ratio) in on-body channel is defined, which has been quantified based on relative antenna locations and radiation gain of test antennas. The analytical results show that the estimated value of Cross-Polarization Power Ratio (XPR), given by the proposed BP-XPR, can represent the cross-polarization properties using the radiation gain of test antenna instead of the practical measurement.
