摘要
本文介绍了一种具有双波段消除功能的紧凑型超宽带多输入多输出（MIMO）天线。天线元件由改进的方形辐射元件和带有非对称地平面的共面波导（CPW）组成。针对空间分集提出了一种双端口 MIMO 配置。它的尺寸为 18 × 37.5 × 1.6 mm3，结构紧凑。它的阻抗匹配频带（VSWR <2）为 3.9- > 150 GHz（%BW >189.86%）。辐射器和馈电线装有改进的 M 型和 U 型槽，以分别在 5.5 千兆赫（无线局域网）和 7.5 千兆赫（X 波段卫星通信）实现频带陷波。在两个端口之间使用了改进的阶梯形结构，以在最高频率下实现 > 20 dB 的端口内隔离。多输入多输出天线的散射参数包络相关系数为 0.005，远场参数包络相关系数为 0.08，峰值增益为 8.63dBi，平均有效增益（MEG）为 -3dB，多路复用效率为 -4.0dB，信道容量损耗（CCL）为 0.4bits/sec/Hz，表明该天线适用于多输入多输出应用。测量结果和模拟结果非常接近。由于其超宽带（SWB）带宽、理想的辐射特性和分集性能，拟议的天线元件和 MIMO 天线结构将适用于物联网（IoT）、5G 和 6G。
Dual band notched superwideband MIMO antenna for 5G and 6G applications
In this article, a compact super wideband multiple input multiple output (MIMO) antenna with dual band elimination feature is presented. The antenna element comprises of modified square shaped radiating element and coplanar waveguide (CPW) with asymmetric ground planes. A dual-port MIMO configuration is proposed for spatial diversity. It has compact size of dimensions 18 × 37.5 × 1.6 mm3. It has frequency band of impedance matching (VSWR < 2) from 3.9– > 150 GHz (%BW > 189.86 %). The radiator and feedline are loaded with modified M- and U-shaped slots to achieve a band notch at 5.5 GHz (WLAN) and 7.5 GHz (X-band satellite communication), respectively. A modified staircase shaped structure is used between the two ports to achieve an intraport isolation of > 20 dB at maximum frequencies. The MIMO antenna has envelope correlation coefficient based on scattering parameters < 0.005, envelope correlation coefficient based on farfield parameters < 0.08, peak gain of 8.63dBi, Mean Effective Gain (MEG) < -3dB, multiplexing efficiency > -4.0 dB, channel capacity loss (CCL) < 0.4bits/sec/Hz to signify its suitability for MIMO applications. The measured and the simulated outcomes are found to be close to each other. The proposed antenna element and MIMO antenna structure will be suitable for Internet of Things (IoT), 5G, and 6G due to their superwideband (SWB) bandwidth, desirable radiation properties and diversity performance.
