Abstract

This paper investigates the effect of antenna polarization in Wireless Body Area Network(WBAN) off-body channel. The polarizations of antenna are divided into four combinations regarding Line-of-Sight(LOS) and Non-LOS(NLOS) environment. The human body keeps both still standing and moving to show that the impact of the polarization to signal. This paper confirms the performance depending on the polarization of receiver antenna and the combination of the polarizations on the off-body channel.

본 논문에서는 무선 인체 통신 중 off-body 채널에서 안테나 편파의 변화에 대한 영향을 알아보기 위한 실험을 수행하였다. 실험은 두 수신 안테나의 편파 조합에 따라 총 4가지로 나누었으며, Line-of-Sight(LOS)와 Non-LOS(NLOS)에 따른 영향도 조사하였다. 그리고 인체의 움직임으로 인하여 생기는 안테나 편파의 변화가 신호에 어떠한 영향을 미치는지 알아보기 위해, 인체를 정지한 상태와 움직이는 상태로 나누어 신호 세기를 측정하여 비교하였다. 본 논문의 결과를 통해 수신 안테나의 편파 및 두 수신 안테나의 편파 조합에 따른 성능을 확인하였다.
