Abstract

Ultra-wideband propagation measurement results for body area network scenarios are presented. We assumed several different scenarios for around-body and on-body propagations, and for each scenario, we conducted both time domain and frequency domain measurements in an anechoic chamber. For the around-body case, we investigated the effects of human body parts blocking line-of-sight, which could be accounted for by diffraction. On-body measurement results indicate a more complicated propagation mechanism exists in on-body propagation than in around-body propagation and antenna characteristics are affected.

본 논문에서는 인체 영역 통신 환경에서의 초광대역 방사측정 결과를 개시한다. 인체 주변 통신 및 인체 표면 통신 환경에서의 다양한 시나리오를 고려하였으며, 시간 영역 및 주파수 영역에서 측정을 진행하였다. 인체 주변 통신 환경의 경우, 인체의 특정 부위가 가시선을 가로막을 경우 발생하는 회절 현상에 대한 분석을 수행하였다. 인체 표면 통신 환경에서의 측정 결과는 인체 주변 통신 환경에 비해 더 복잡한 방사 형태가 나타나며 안테나 특성도 영향을 받게 됨을 알 수 있었다.
