In this paper, a flexible and compact multiband wearable antenna with a simple and low-profile structure is proposed and investigated. It is able to operate over the frequency ranges from 0.824 GHz to 0.975 GHz and from 1.90 to GHz to 6 GHz, covering the most of identified frequency bands for biomedical applications. Moreover, the antenna demonstrates robust on-body performance and provides a suitable balance between small antenna size, high on-body radiation efficiency (between 5% and 11% for operating frequency bands), and a low value of the maximum 10 g specific absorption rate (0.47 W/kg) on a homogeneous semisolid phantom.

在本文中，提出并研究了一种结构简单、低调的灵活紧凑的多频带可穿戴天线。它能够在 0.824 GHz 至 0.975 GHz 以及 1.90 至 GHz 至 6 GHz 的频率范围内运行，涵盖了生物医学应用的大部分已识别频段。此外，该天线表现出稳健的贴身性能，并在天线尺寸小、贴身辐射效率高（工作频段在 5% 到 11% 之间）和最大 10 g 特定吸收值较低之间取得了适当的平衡率 (0.47 W/kg) 在均匀的半固体模型上。
