This communication presents a multiband on‐body conformal and wearable antenna for Wireless Body Area Network (WBAN) applications. The suggested wearable CPW‐fed slot dipole antenna is incorporated with inductively coupled meander shape, T and O shaped resonators that lead to provide multiband operation. The resonant frequency is controlled by a definite resonant path, which leads to high degree of freedom in design paradigm. The proposed wearable antenna covers the 2.4 GHz/5.2 GHz/5.8 GHz WLAN, 3.5 GHz WiMAX, and 4.4 GHz C‐bands and has an overall dimension of 60 × 40 × 0.254 mm³. The SAR analysis has also been presented for the antenna at several resonant frequencies which are well under the normal SAR criteria of 1.6 W/kg that suggests that the model performs satisfactorily for wearable applications. To characterize the performance of the antenna, the specimen of the antenna is rigorously tested in terms of antenna gain, S‐parameters and flexibility under different bending configurations for radii values ranging from 90 to 30 mm. The reflection coefficient of the suggested antenna is also evaluated and the outcomes are compared under distinct on‐body circumstances. Measured and simulated results of S11, radiation pattern and gain are in good agreement.

可穿戴无线体域网应用中CPW馈电多频带天线的设计

该通信提出了一种用于无线人体局域网（WBAN）应用的多频带人体保形和可穿戴天线。建议将可穿戴式CPW馈电缝隙偶极天线与电感耦合的曲折形，T型和O型谐振器结合使用，从而提供多频带工作。谐振频率由确定的谐振路径控制，这导致了设计范例中的高度自由度。拟议中的可穿戴天线覆盖2.4 GHz / 5.2 GHz / 5.8 GHz WLAN，3.5 GHz WiMAX和4.4 GHz C频段，并且总体尺寸为60 × 40 × 0.254 mm ³。天线的SAR分析也已经在几个谐振频率上进行了介绍，这些谐振频率完全在标准SAR标准1.6 W / kg下，这表明该模型对于可穿戴应用的性能令人满意。为了表征天线的性能，在不同的弯曲配置下，针对半径范围为90至30 mm的天线，在天线增益，S参数和柔韧性方面进行了严格的测试。还评估了建议天线的反射系数，并在不同的人体情况下比较了结果。S11，辐射方向图和增益的测量和仿真结果吻合良好。
