在本文中，提出了一种用于便携式无线超宽带（UWB）应用的具有双锐抑制陷波带的多输入多输出（MIMO）天线的紧凑设计并进行了实验研究。所提出的 UWB MIMO 天线尺寸紧凑，为 18 mm x 34 mm。锥形微带馈电缝隙天线充当单个辐射元件，具有倒 L 形缝隙，在无线局域网和 IEEE INSAT/超级扩展 C 频段引入凹口。在整个工作频段（2.93-20 GHz）上实现了小于-22 dB 的互耦。在陷波带的中心，天线的效率下降，表明具有良好的干扰抑制性能。研究了MIMO天线的端口隔离度、辐射方向图、效率、实现增益、包络相关系数、平均有效增益和总有源反射系数等性能。
In this paper, a compact design of multiple-input multiple-output (MIMO) Antenna with dual sharply rejected notch bands for portable wireless ultrawideband (UWB) applications is presented and experimentally investigated. The proposed UWB MIMO Antenna has a compact size of 18 mm x 34 mm. The tapered microstrip fed slot Antenna acts as a single radiating element with inverted L-shaped slits to introduce notches at wireless local area network and the IEEE INSAT/Super-Extended C-bands. The mutual coupling of less than -22 dB is achieved over the entire operating band (2.93-20 GHz). At the center of notched band, the efficiency of the Antenna drops that indicates a good interference suppression performance. The performance of the MIMO Antenna in terms of isolation among the ports, radiation pattern, efficiency, realized gain, envelope correlation coefficient, mean effective gain, and total active reflection coefficient is studied.
