In this paper, a wearable ultra‐wideband (UWB) monopole antenna with a compact structure and low profile is presented for wireless body area networks, wireless local area networks, and UWB applications. The antenna is composed of three triangular radiators on the basis of the mono‐cone antenna. By the methods of reactive and slot loading, the dimension of the antenna can be greatly reduced. The overall height of the antenna is 0.06 λ₀ at its lowest operating frequency. The radiated structure of the proposed antenna with the dimension of 31 × 31 × 9 mm³, which operates in 2.3 to 12.6 GHz, is fabricated and the measurement results are in good agreement with the simulated ones. Moreover, the influence of the human tissue on the antenna was evaluated, and stable performance can be obtained on the human tissue under different bending conditions. The specific absorption rate values are lower than the limitation set by the European Telecommunications Standards Institute, which indicates that the antenna is suitable for wearable applications.

紧凑的单极天线，用于无线人体局域网，无线局域网和超宽带应用

本文针对无线人体局域网，无线局域网和UWB应用，提出了一种结构紧凑，外形小巧的可穿戴式超宽带（UWB）单极天线。该天线在单圆锥天线的基础上由三个三角形辐射器组成。通过电抗和缝隙加载的方法，天线的尺寸可以大大减小。天线的整体高度是0.06 λ ₀在其最低工作频率。拟议天线的辐射结构尺寸为31×31×9 mm ³制成了工作于2.3至12.6 GHz的天线，测量结果与仿真结果吻合良好。此外，评估了人体组织对天线的影响，并且可以在不同的弯曲条件下在人体组织上获得稳定的性能。特定吸收率值低于欧洲电信标准协会设置的限制，这表明该天线适用于可穿戴应用。
