단파(HF) 대역 RFID 리더 안테나에 의한 인체 유도 전류의 등가 안테나 모형 연구

Abstract

There are many researches on human effect by electromagnetic equipments and applications. However, most of research and guidelines for limiting human exposure to electromagnetic fields are established by mobile communication of SAR(Specific Absorption Ratio). Therefore we need to study different effects on human body when exposed to high frequency(HF) band equipments, such as human induced current etc. In this paper, we measured human induced current by RFID reader antenna of HF band in the near field and we propose human equivalent antenna which has orthogonal loops to each other. Then, we compared the induced currents on proposed equivalent antenna with human.
