【摘要】 本文提出了一款基于K波段的小型化多输入多输出（Multiple-InputMultiple-Output,MIMO）天线。通过对辐射贴片底部两个角进行切角,在拓宽工作带宽的同时保证天线小型化;通过在接地板加载"Ⅰ"形槽的延伸枝节并刻蚀开口槽来降低MIMO天线单元之间的耦合作用,使天线隔离度得到有效提高。该天线整体物理尺寸很小,仅为25 mm×20 mm×1 mm。利用HFSS仿真软件对该天线进行仿真,仿真结果表明:天线在16.4 GHz～27.9 GHz（相对带宽为50.1%）的工作频段内S₁₁<-10 dB,S₂₁<-16 dB,包络相关系数ECC小于0.07。天线各项性能均较为良好,可以广泛应用于无线通信系统等相关领域。更多还原

【Abstract】 This paper proposes a miniaturized Multiple Input Multiple Output（MIMO） antenna based on K band.By chamfering the bottom two corners of the radiation patch,the working bandwidth is expanded while ensuring antenna miniaturization;By loading the extended branches of the "I" groove on the grounding plate and etching the open loop,the coupling effect between MIMO antenna units is reduced,and the antenna isolation is effectively improved.The overall physical size of the antenna is very small,only 25 mm× 20 mm× 1 mm.The antenna was simulated using HFSS simulation software,and the simulation results showed that the antenna was between 16.4 and 27.9 Within the operating frequency band of 9 GHz（relative bandwidth of 50.1 %）,S₁₁<-10 dB,S₂₁<-16 dB,and the envelope correlation coefficient ECC is less than 0.07.The antenna has good performance and can be widely used in wireless communication systems and other related fields.更多还原
