摘要

本文分析了一种在超宽带(UWB)频率范围内工作的靠近人头的天线。在3.1 GHz - 6.7 GHz频率范围内工作的超宽带天线,当天线在真实的人体头部模型前工作时,根据反射系数、e场和h场穿透以及人体组织的比吸收率(SAR)进行了评估。研究表明,在较高的超宽带频率下,功率在人体内的传播明显减少。

UWB Power Penetration Inside a Realistic Human Head Model
In this paper, an antenna operating near a human head is analysed in the ultra-wideband (UWB) frequency range. The UWB antenna operating over a frequency range from 3.1 GHz - 6.7 GHz is evaluated in terms of reflection coefficient, E-field and H-field penetration, and specific absorption rate (SAR) of the human tissue when the antenna is operating in front of a realistic human head model. The study shows that at higher UWB frequencies, the power propagation inside the human head decreases significantly.
