Here, a planar Ultra-Wideband (UWB) wearable Multiple Input Multiple Output (MIMO) antenna is designed for on-arm wearable Wireless Body Area Network (WBAN) applications. This antenna is designed on a 100% cotton cloth substrate. The two-port MIMO antenna has a dual spinning wheel shape like radiators with the partial ground and microstrip feedings. The two partial grounds are connected to a rectangular strip to have common ground. The complete surface area of the antenna is 40 × 70 mm 2 . In comparison with recently published papers in the same research area, the bending and SAR analysis are also done to estimate the performance of this wearable antenna, which is the novelty of this research work. For entire UWB bandwidth, S–parameters, gain, efficiency, and diversity parameters (Channel Capacity Loss [CCL] and Envelope Correlation Coefficient [ECC]) and far-field simulations are done for all cases such as flat, bend, on body antenna, which demonstrates the appropriateness of the presented antenna to be operated to the human arm.

用于手臂WBAN应用的UWB可穿戴MIMO天线的弯曲和SAR分析

在这里，平面超宽带（UWB）可穿戴多输入多输出（MIMO）天线是为臂上可穿戴无线人体局域网（WBAN）应用设计的。该天线设计在100％棉布衬底上。两端口MIMO天线具有双旋转轮形状，类似于带有局部接地和微带馈源的辐射器。这两个局部接地连接到矩形条以具有公共接地。天线的总表面积为40×70 mm 2。与同一研究领域中最近发表的论文相比，还进行了弯曲和SAR分析，以评估这种可穿戴天线的性能，这是这项研究工作的新颖之处。对于整个UWB带宽，S参数，增益，效率，
