Abstract

The aim of this paper is the development of a 2×2 MIMO antenna that is capable of covering the whole UWB spectrum of 3.1 - 10.6 GHz. The design starts by implementing a single element of Printed Circular Disc Monopole (PCDM) antenna on a 1.6 mm thick FR-4 substrate having a relative permittivity of 4.4. A parametric analysis, as well as slots insertion, are performed based on “Finite Difference Time Domain Analysis (FDTD)” to improve the structure performance related to the operating bandwidth. Concerning the MIMO antenna structure, a four-element configuration is investigated. Over the intended frequency band, the isolation is greater than 15 dB. The “Envelope Correlation Coefficient (ECC)”, “Diversity Gain (DG)”, and “Channel Capacity Loss (CCL)” have all been shown to improve diversity performance and are determined to be within acceptable limits. A network analyzer is used to measure the antenna structure once it is constructed. In terms of scattering characteristics and spectral efficiency, the measured and simulated are in good agreement.

Sub-6 GHz 5G新型超宽带4元MIMO微带贴片天线设计

本文的目的是开发一种能够覆盖3.1 - 10.6 GHz全UWB频谱的2×2 MIMO天线。本设计首先在相对介电常数为4.4的1.6 mm厚FR-4基板上实现单元件印刷圆圆盘单极子(PCDM)天线。基于时域有限差分分析(FDTD)进行了参数分析和插槽插入，以改善与工作带宽相关的结构性能。针对MIMO天线结构，研究了一种四元天线结构。在预期频带内，隔离度大于15db。“包络相关系数(ECC)”、“分集增益(DG)”和“信道容量损失(CCL)”都被证明可以改善分集性能，并被确定在可接受的范围内。天线构造完成后，使用网络分析仪对其结构进行测量。在散射特性和光谱效率方面，测量值与模拟值吻合较好。
