摘要

本文提出了一种集成去耦方法，提高了多端口、多频带天线设计的灵活性，简化了天线结构。首先，利用中和线去耦方法创建了中心频率为 2.6 GHz 和 5.6 GHz 的双频 L 型 MIMO 天线，然后利用 T 型分支去耦技术创建了覆盖 WiFi 频谱（2.3-2.5 GHz 和 4.6-5.6 GHz）的双频 L 型 MIMO 天线。在证明了中和线和 T 型分支去耦技术在 L 型天线上的功效后，结合中和线去耦、T 型分支去耦和缺陷接地结构去耦的方法，提出了一种覆盖 4.4-4.9 GHz、5.4-6.1 GHz 和 7.0-7.4 GHz 的四端口 L 型 MIMO 天线。该天线的隔离度高于 20 dB，ECC 小于 0.04。

Triple-Band MIMO Antenna with Integrated Decoupling Technology

This paper proposes an integrated decoupling method that improves the flexibility of multiport, multiband antenna design and simplifies the antenna structure. First, a dual-band L-type MIMO antenna with center frequencies of 2.6 GHz and 5.6 GHz is created using the neutralization-line decoupling method and then a dual-band L-type MIMO antenna covering the WiFi spectrum (2.3–2.5 GHz and 4.6–5.6 GHz) is created using the type-T branch decoupling technique. After demonstrating the efficacy of neutralization-line and T-branch decoupling technology for L-type antennas, a four-port L-type MIMO antenna covering 4.4–4.9 GHz, 5.4–6.1 GHz, and 7.0–7.4 GHz is proposed by combining the methods of neutralization-line decoupling, T-branch decoupling, and defected ground structure decoupling. This antenna’s isolation is higher than 20 dB with ECC less than 0.04.
