This paper proposed a new flexible and wearable antennas design based on teragon pre-fractal geometry until the third level, for monitoring high-temperature in humans for wireless body area network operating band. The antennas were built in polyamide laminate dielectric material, which has suitable thermal and mechanical resistance characteristics for application in wearable antennas. The antenna’s structure was generated by teragon pre-fractal geometry using a MATLAB code and simulated with commercial software ANSYS. The application of teragon geometry allows controlling the resonance frequencies and radiation characteristics in comparison to simple square geometry. Teragon level 3 has provided maximum resonance frequency reduction, about 142.4%. In comparison of simulated and measured results on-body we noted that variation of resonance frequency is directly proportional to the fractal level, with the increase of fractal level there is greater variation in the difference between the simulated and measured resonance frequency, close results of gain, and higher simulated SAR value of 0.0653 mW/kg (K = 2), being within standard indicated by international institutions such as FCC and IEEE.

本文提出了一种基于对角线预分形几何直到第三级的新型柔性可穿戴天线设计，用于监测人体的无线体域网络工作频段的高温。天线由聚酰胺层压电介质材料制成，该材料具有适用于可穿戴天线的合适的热阻和机械电阻特性。天线的结构是使用MATLAB代码通过对角线预分形几何来生成的，并使用商业软件ANSYS进行了仿真。与简单的正方形几何形状相比，四边形几何形状的应用允许控制共振频率和辐射特性。Teragon 3级提供了最大的共振频率降低，约为142.4％。
