摘要

本文设计并分析了一种基于聚合物柔性基板的小型可穿戴天线，用于无线体域网络(WBAN)。该天线工作在2GHz ~ 6GHz频段，谐振频率为5.4 GHz，适用于无线局域网身体通信。天线结构已经小型化，使用了辐射贴片的开槽，使天线足够轻，完全适合可穿戴无线应用。人体与贴片之间较大的导电接地面可以减少射频耦合，降低比吸收率(SAR)值。在仿真中，可穿戴天线的增益增加了10 dB，平均SAR值为1.5 w /gm，在规定的安全限值内。该天线的设计可以更好地隔离机身损耗，降低SAR值，提高辐射效率。

Low profile and low SAR flexible wearable patch antenna for WBAN

In the proposed work, a compact wearable antenna on a polymer-based flexible substrate has been designed and analyzed for Wireless Body Area Network (WBAN). The proposed antenna operates in 2GHz to 6GHz band at the resonant frequency of 5.4 GHz for WLAN applications in on-body communication. The antenna structure has been miniaturized using slotting of the radiating patch to make the antenna light enough, perfectly suiting wearable wireless applications. A larger conductive ground plane between the body and the patch reduces RF coupling and lowers the Specific Absorption Rate (SAR) value. In the simulation, the wearable antenna offers an increased gain of 10 dB with an average SAR value of 1.5 watts/gm, which is within the specified safety limit. The antenna has been designed to provide better isolation against on-body losses and reduced SAR value with improved radiation efficiency.
