提出了一种用于4.5G/5G可穿戴设备的超宽带（UWB）多输入多输出（MIMO）天线。所提出的双天线阵列具有仅30 × 26 mm 2的紧凑尺寸。该天线由馈电条和耦合馈电槽分别集成在天线的正面和背面而成。3.3-10.9 GHz频段覆盖，反射系数优于−10 dB。在接地面上蚀刻一对较长的C形槽和一对较短的C形槽，以获得高隔离度（低于-15 dB）和低包络相关系数（低于0.05）。仿真结果，如S参数，效率，增益和辐射方向图进行了讨论，并计算了包络相关系数（ECC），平均有效增益（MEG），复用效率和信道容量的建议天线也被提出。
An ultra-wideband (UWB) multiple-input multipleoutput (MIMO) antenna for 4.5G/5G wearable devices is proposed in this paper. The proposed 2-antenna array has a compact size of 30 × 26 mm2 only. The proposed antenna is formed by integrating feeding strips and coupled-fed slots on the front and back surface respectively. 3.3–10.9 GHz band is covered with reflection coefficient better than −10 dB. One pair of longer C-shaped slots and one pair of shorter C-shaped slots are etched on the ground plane to obtain high isolation (lower than −15 dB) and low envelope correlation coefficient (lower than 0.05). Simulated results such as S-parameters, efficiency, gain, and radiation pattern are discussed, and calculated envelope correlation coefficient (ECC), mean effective gain (MEG), multiplexing efficiency and channel capacity of the proposed antenna are also presented.
