Abstract

This paper considers an application of distributed antenna system (DAS) to a system of intra-vehicle wireless energy transfer (WET). The intra-vehicle WET system has features such as limited mobility of energy receiver, static channel environment and short distance between transmitter and human body. Under these conditions, location of transmitter highly affects the amount of energy received by human body and the energy received by energy receiving devices. We compare centralized antenna system (CAS) and the DAS in intra-vehicle WET system by simulation. The results show the DAS has superior performance to the CAS.

본 논문은 차량 내부에서 무선 에너지 전송 기술을 지원하기 위해 분산 안테나 시스템의 사용을 제안한다. 차량 내 무선 에너지 전송 시스템은 에너지 수신 단말기의 이동이 제한적이고, 채널 환경이 정적이며, 인체가 송신기와 가까운 특징을 갖는다. 이러한 상황에서 송신기의 배치는 인체에서의 수신 에너지와 에너지 수신 단말기에서의 수신 에너지의 양에 큰 영향을 미친다. 이에 본 논문은 기존 무선 통신 시스템에서 사용되는 중앙 집중형 안테나 시스템과 분산 안테나 시스템을 적용하였을 때의 차량 내 무선 에너지 전송 성능을 모의실험을 통해 비교하고, 분산 안테나 시스템이 더 좋은 성능을 가짐을 보인다.
