摘要(中文译文)
本研究介绍了一种专为5G应用设计的紧凑型三宽带多输入多输出（MIMO）天线。该天线通过集成三个结构进行设计，每个结构均经过优化以在特定频段内工作。随后，通过在前侧引入槽缝并在后侧加入L形结构，增强了天线的带宽。天线的紧凑尺寸约为37.5×37.5×1.6 mm³，在3 GHz下对应电尺寸为0.375λ×0.375λ×0.016λ。天线已完成制作与测量。测量结果表明，在|S11|<-10dB条件下，所开发天线在Sub-6吉赫兹、Ku和毫米波频段分别表现出约90.91%（5 GHz）、39.9%（6.6 GHz）和20.4%（5 GHz）（仿真值：101.7%（40.6 GHz））的分数带宽。在|S11|<-10dB条件下，所提出天线在Sub-6、Ku和毫米波频段的实测峰值增益分别为5 dBi，仿真增益分别为5.5 dBi和10.1 dBi。该天线具有优异的分集性能，Sub-6、Ku和毫米波频段的包络相关系数（ECC）分别小于0.06、0.002和0.002，分集增益（DG）分别大于9.68、9.99和9.99。所有频段在90度相位处均观察到良好的TARC值。此外，所有频段均观察到可接受的仿真CCL值。同时，所有频段的仿真和实测MEG均位于-3 dB至-4.3 dB范围内。此外，所有频段H面的辐射方向图均类似全向方向图，而在E面，天线在Sub-6和Ku频段表现出类单极子辐射方向图。这种多功能的多频段工作特性使所设计天线成为先进无线通信系统的可靠解决方案。
Abstract
This work introduces a compact triple wideband Multiple-Input Multiple-Output (MIMO) antenna specifically designed for 5G applications. The antenna was designed simply by integrating three structures, each optimally nominated to operate within a specific frequency band. Subsequently, the antenna's bandwidth was enhanced by incorporating a slot on the front side and an L-shaped structure on the rear side. The compact dimension of the antenna is about 37.5 × 37.5 × 1.6 mm3, corresponding to an electrical size of 0.375λ × 0.375λ × 0.016λ at 3 GHz. The antenna is fabricated and measured. Measurement results reveal that the developed antenna shows a fractional bandwidth of about 90.91% (5 GHz), 39.9% (6.6 GHz) and 20.4% (5 GHz) (Simulated: 101.7(40.6 GHz)) in the Sub-6 gigahertz, Ku and mm-Wave bands, respectively for |S11| < - 10dB. The proposed antenna achieves measured peak gains of 5 dBi and simulated gains of 5.5 dBi, and 10.1 dBi for the Sub-6, Ku, and mm-Wave bands, respectively for |S11| < -10dB. It has excellent diversity performance, with envelope correlation coefficients (ECC) of less than 0.06, 0.002 and 0.002 for Sub-6, Ku and mm-Wave bands respectively and diversity gains (DG) greater than 9.68, 9.99 and 9.99 for the Sub-6, Ku and mm-Wave bands respectively. Good TARC values are observed at 90-degree phase for all bands. In addition, the accepted simulated CCL values are observed for all bands. Also, the simulated and the measured MEG lies within -3 dB to -4.3 dB for all bands. Moreover, the radiation patterns in the H-plane of all bands are like omnidirectional patterns and in the E plane the antenna exhibits monopole like radiation patterns for the Sub 6 and Ku bands. The versatile multiband operation makes the designed antenna a reliable solution for advanced wireless communication systems.
