This article presents the design of low‐profile single band antenna on flexible substrate material. The proposed antenna is designed on the polyimide substrate with overall size of 30 mm × 30 mm × 0.2 mm. The designed antenna operates in the frequency range of 5.71 to 5.99 GHz with impedance bandwidth of 4.8% and covers the Industrial Scientific Medical band for medical body area network applications. The antenna is enabled by placing artificial magnetic conductor (AMC) with two by two array elements under the ground plane. The AMC structure acts as an isolation for the ground plane and main radiator to reduce back radiation. Compared with literature in the wearable antenna designs, the proposed antenna is compact in structure with high gain of 8.31 dBi with AMC‐backed structure. The specific absorption rate values are observed by placing the antenna on the three‐layered human body model and the observed values are 1.26 and 0.72 W/Kg without AMC and with AMC, respectively. The obtained values are in conjunction with ICNIRP standards, that is, 2 W/Kg should be averaged over 10 g of tissue. The proposed antenna can be used for the smart clothing and wearable electronics applications.

具有可穿戴医疗应用的带有人造磁导体支撑结构的风车形天线

本文介绍了在柔性基板材料上的低剖面单频带天线的设计。拟议的天线设计在聚酰亚胺基板上，外形尺寸为30 mm × 30 mm ×0.2毫米 设计的天线工作在5.71至5.99 GHz的频率范围内，阻抗带宽为4.8％，覆盖了用于医疗局域网的工业科学医疗频段。通过将人造磁导体（AMC）与两个，两个阵列元件一起放置在接地层下方来启用天线。AMC结构充当接地层和主辐射器的隔离物，以减少反向辐射。与可穿戴天线设计中的文献相比，拟议的天线结构紧凑，具有AMC支持的结构，增益高达8.31 dBi。通过将天线放在三层人体模型上可以观察到特定的吸收率值，在没有AMC和有AMC的情况下，观察到的吸收率分别为1.26和0.72 W / Kg。获得的值与ICNIRP标准结合使用，也就是说，在10 g组织中应平均2 W / Kg。拟议中的天线可用于智能服装和可穿戴电子设备。
