摘要
在这项研究中,实现了一种具有两个和四个输入端口的太赫兹双频高增益多输入多输出(MIMO)天线,其增益值分别高达 7.16[计算公式:见正文]dBi 和 6.44[计算公式:见正文]dBi。与单输入端口天线相比,增益分别提高了 102.4% 和 81.8%。通过计算和分析电压驻波比(VSWR)、增益、包络相关系数(ECC)和分集增益,两个 MIMO 天线在共振点实现了完美的阻抗匹配。此外,MIMO 天线元件之间的干扰很小,单元之间实现了隔离效果。这些多输入多输出(MIMO)天线可以实现多输入信号,从而调节天线辐射性能,提高信号强度和质量。此外,它们在太赫兹频段和移动通信中实现高速数据传输方面具有良好的发展前景。
A novel dual-band–high-gain terahertz MIMO antenna
In this study, a terahertz dual-band–high-gain, multi-input–multi-output (MIMO) antenna with two and four input ports was realized, with gain values of up to 7.16[Formula: see text]dBi and 6.44[Formula: see text]dBi, respectively. This represents an increase in gain of 102.4% and 81.8%, respectively, compared to single-input port antennas. By calculating and analyzing the voltage standing wave ratio (VSWR), gain, envelope correlation coefficient (ECC), and diversity gain, the two MIMO antennas achieved perfect impedance matching at their resonance points. Moreover, the interference between the elements of the MIMO antenna was small, and an isolation effect between the units was realized. These MIMO antennas can achieve multiple input signals to regulate the antenna radiation performance and improve signal strength and quality. In addition, they possess good development prospects for achieving high-speed data transmission in the terahertz band and in mobile communication.
