Abstract

a compact dual-band textile antenna is designed for wearable 5G and Wi-Fi 6E communication. The full ground of antenna is modified using two circular slots with an appropriate radius for improving the impedance matching towards the desired band. The designed vase-shaped ground structure with an elliptical-shaped radiator is obtaining the high-speed Wi-Fi 6E band in the antenna. Further, a CSRR is accomplished in the radiator which perturbs the surface wave effectively and the antenna achieves a lower operating band in the allotted 5G spectrum. The CSRR also improves the total gain of the antenna in the lower operating band which makes it more advantageous in wearable wireless communication. 10 dB IBW of dual band antenna is varying between 3.4 - 4.1 GHz and 6.2 – 7.1 GHz. To confirm the on-body radiation effect, the specific absorption ratio (SAR) is extracted from three layered human phantom models and the values of obtained SAR are quite healthy.

用于可穿戴5G和Wi-Fi 6E应用的带有缺陷接地的CSRR负载紧凑型纺织天线

紧凑型双频纺织天线专为可穿戴5G和Wi-Fi 6E通信而设计。天线的全接地采用两个具有适当半径的圆形槽进行修改，以改善对所需频带的阻抗匹配。设计的带有椭圆形散热器的花瓶状地面结构在天线中获得高速Wi-Fi 6E频段。此外，在散热器中实现了有效扰动表面波的CSRR，并且天线在分配的5G频谱中实现了较低的工作频带。CSRR还提高了天线在较低工作频带的总增益，使其在可穿戴无线通信中更有优势。双频天线的10db IBW在3.4 ~ 4.1 GHz和6.2 ~ 7.1 GHz之间变化。为了确认人体辐射效应，从三层人体模型中提取了比吸收比(SAR)，所得SAR值相当健康。
