摘要

提出并制作了一种适用于智能服装的纺织天线,并在ISM波段进行了测试。在自由空间和接近人体的情况下对其性能进行了评估。在自由空间中,天线增益为4.78dB,在非体状态下,增益为4.37dB。从自由空间到体上通信链路的阻抗带宽有10%的偏移。由于柔性结构的存在,研究了天线在体附近的弯曲效应。当天线弯曲时,谐振频率会略有下降。为了验证数值结果,进行了测量活动。对弯曲角与天线参数之间的关系进行了参数化研究。

Design and performance analysis of a textile antenna suitable for smart clothing
A textile antenna suitable for smart clothing is proposed, fabricated and tested at ISM band. The performance has been evaluated both in free space and in the proximity of the human body. It is observed that in free space the antenna gain is 4.78dB and in on-body condition the gain 4.37dB. There is a 10% shift in impedance bandwidth from free space to on-body communication links. Due to the flexible structure bending effect of the antenna near the body is also investigated. A slight decrease in resonating frequency occurs when the antenna is bent. Measurement campaign has been carried out to validate the numerical results. A parametric study has also been performed to observe the relationship between bending angles and antenna parameters.
