摘要

提出了一种低轮廓电磁带隙纺织可穿戴天线,覆盖新发布的医疗无线身体网络(mban)的2.36和2.40 GHz之间的频谱。采用该天线的集成EBG可将人体组织的辐射强度降低约13 dB;同时也降低了频率失谐的影响。天线结构紧凑,总体积为54 × 54 × 3.1 mm3。它提供8.5%的阻抗带宽和6.79 dBi的功率增益。同时进行了比吸收率(SAR)评估,以验证天线在靠近人体时的性能。天线尺寸及其最终性能可以作为集成到各种可穿戴设备中的一个很好的候选者。

Robust low-profile electromagnetic band-gap-based on textile wearable antennas for medical application
A low-profile electromagnetic band-gap enabled textile wearable antenna covering the spectrum between the 2.36 and 2.40 GHz of the new released medical wireless body networks (MBANs), is presented. The integrated EBG with the proposed antenna reduces the radiation intensity into the human tissues around 13 dB; and also decreases the effect of frequency detuning. The antenna structure is compact size with total volume of 54 × 54 × 3.1 mm3. It offers 8.5% impedance bandwidth and a power gain of 6.79 dBi. Specific absorption rate (SAR) evaluation is also carried out to validate the performance of the antenna when it is placed closely to human body. The antenna size and its ultimate performances could be selected as a good candidate for integration into various wearable devices.
