摘要

本文设计了一种适用于现代无线通信的小型、高隔离双单元超宽带MIMO天线。该设计由两个相同的nonnon -shaped(九边多边形)单极子组成，以垂直的几何形状放置，以提高两个天线元件之间的隔离。此外，矩形的局部地平面被用来提高所提出的设计的带宽。该设计展示了在2.92 GHz至20.59 GHz频率范围内回波损耗小于-10 dB的超宽带，分数带宽(FBW)为150.32%，适用于中频段5G和预期的6G通信。获得的最大相关系数(ECC)为0.0071，整体隔离度优于-24 dB。提出的设计基于Rogers RT5880衬底材料，其相对介电常数为2.2，总体尺寸为34 × 64 × 0.508 mm3。利用ANSYS HFSS软件对天线进行了仿真分析。

Dual Nonagon-Shaped Elements UWB MIMO for 5G and Expected Mid-Band 6G Communications

A new compact-size, highly isolated dual-element ultra-wideband (UWB) MIMO antenna for modern wireless communications is designed in this paper. This design is composed of two identical nonagon-shaped (nine-sided polygon) monopoles placed in perpendicular geometry to rise the isolation between the two antenna elements. In addition, a rectangular-shaped partial ground plane was used to boost the bandwidth of the proposed design. This design exhibits UWB with a return loss of less than -10 dB in the frequency range of 2.92 GHz to 20.59 GHz and a fractional bandwidth (FBW) of 150.32 % making it suitable for mid-band 5G and expected 6G communications. The maximum obtained correlation coefficient (ECC) was 0.0071, and the overall isolation was better than -24 dB. The proposed design was built over Rogers RT5880 substrate material with a relative permittivity of 2.2 and an overall size of 34 × 64 × 0.508 mm3. The simulated results of the proposed antenna have been obtained using ANSYS HFSS software.
