摘要

本文提出了一种双面去耦元表面(DSDM)方法,用于降低间距很近的圆极化(CP)多输入多输出(MIMO)天线元件之间的相互耦合,适用于 6 GHz 以下的应用。拟议的 DSDM 结构带有一个方形贴片层,置于阵列上方,通过非传播的蒸发波和操纵传播的反射 CP 波的极化来减少相互耦合。这种去耦机制依赖于从元原子中提取的 DSDM 负电介电常数。当 CP 波通过阵列的受激 CP 天线入射到 DSDM 偏振器时,反射和传输的 CP 波的偏振态会在 DSDM 的控制下发生变化。在反射模式下,DSDM 的负介电常数会产生两种波,即产生极化失配的反射波和降低 CP 天线间耦合的蒸发波,而在传输模式下,辐射模式可控制在 φ = 45° 或 φ = 135°。所提出的低剖面去耦结构已制作完成并通过实验验证。与参考阵列相比,去耦设计在 3.5 GHz 频率下极大地降低了 CP 天线元件之间的互耦,降低幅度超过 15 dB,在 3.02 GHz 至 3.67 GHz 频率下降低幅度超过 13 dB。拟议设计的轴向比小于 3 dB,在 3.5 GHz 实现了 5.52 dBic 的最大增益。研究表明,模拟结果与测量结果非常吻合。

Metasurface-Assisted mutual coupling suppression in circularly polarized MIMO antenna array for Sub-6 GHz applications

Metasurface-Assisted mutual coupling suppression in circularly polarized MIMO antenna array for Sub-6 GHz applications
A double-sided decoupling metasurface (DSDM) method is proposed to reduce the mutual coupling between very closely spaced circularly polarized (CP) MIMO antenna elements for sub-6 GHz applications. A proposed DSDM structure with a square-shaped patch layer is placed over the array to reduce mutual coupling by non-propagating evanescent waves and manipulating the polarization of propagating reflected CP waves. This decoupling mechanism relies on the DSDM’s negative electric permittivity extracted from the meta-atom. When the CP waves were incident to DSDM polarizer through the excited CP antenna of the array, the polarization states of the reflected and transmitted CP waves were changed as controlled by DSDM. In reflection mode, the negative permittivity of DSDM produce two type of the waves reflected waves generated the polarization mismatch and evanescent waves that reduce the coupling between CP antennas, while the transmission mode, controlling the radiation pattern at φ = 45° or φ = 135°. The low-profile proposed decoupling structure was fabricated and experimentally validated. The decoupling design significantly mitigated the measured mutual coupling between the CP antenna elements at 3.5 GHz by more than 15 dB and by more than 13 dB at 3.02 GHz to 3.67 GHz, compared to the reference array. The proposed design achieves less than a 3 dB axial ratio, maximum realized gain of 5.52 dBic at 3.5 GHz. An excellent agreement between the simulated and measured outcomes has been studied.

期刊介绍: Materials and Design is a multi-disciplinary journal that publishes original research reports, review articles, and express communications. The journal focuses on studying the structure and properties of inorganic and organic materials, advancements in synthesis, processing, characterization, and testing, the design of materials and engineering systems, and their applications in technology. It aims to bring together various aspects of materials science, engineering, physics, and chemistry. The journal explores themes ranging from materials to design and aims to reveal the connections between natural and artificial materials, as well as experiment and modeling. Manuscripts submitted to Materials and Design should contain elements of discovery and surprise, as they often contribute new insights into the architecture and function of matter.
