面向智能蒙皮应用的柔性UWB-MIMO天线OA

To address the challenge that rigid antennas are difficult to achieve high-performance communication on complex curved surfaces,a flexible four-element Ultra Wide Band(UWB)Multiple-Input Multiple-Output(MIMO)antenna for smart skin applications is proposed.The antenna adopts a four-element layout and operates from 5.0～18.9 GHz(fractional bandwidth of 116.3%),with an overall dimensions of 70 mm×70 mm×0.13 mm.Without increasing the profile height,the antenna achieves a port isolation of more than 20 dB and an extremely low Envelope Correlation Coefficient(ECC)over the entire frequency band by loading Split-Ring Resonators(SRR)and a ground decoupling structure.Simulation and measurement results demonstrate that the antenna maintains stable and favorable radiation characteristics under flat conditions,on foam carriers with different curvature radii,and on metal carrier surfaces,thereby verifying its feasibility and robustness for smart skin applications such as unmanned aerial vehicle surfaces and robotic dexterous hands.
