Abstract

Purpose This paper aims to propose a single element, dual feed, polarisation diversity antenna. The proposed antenna operates from 2.9 to 10.6 GHz for covering the entire ultra-wideband (UWB) frequency range. The antenna is designed for usage in massive multiple input multiple output (MIMO) and closed packaging applications. Design/methodology/approach The size of the antenna is 24 × 24 × 1.6 mm3. The radiating element of the antenna is derived from the Sierpinski–Knopp (SK) fractal geometry for miniaturization of the antenna size. The antenna has a single reflecting stub placed between the two orthogonal feeds, to improve isolation. Findings The proposed antenna system exhibits S11 < −10 dB, S21 < −15 dB and stable radiation characteristics in the entire operating region. It also offers an envelope correlation coefficient < 0.01, a diversity gain > 9.9 dB and a capacity loss < 0.4 bps/Hz. The simulated and measured outputs were compared and results were found to be in similarity. Originality/value The proposed UWB-MIMO antenna has significant size reduction through usage of SK fractal geometry for radiating element. The antenna uses a single radiating element with dual feed. The stub is between the antenna elements which provide a compact and miniaturized MIMO solution for high density packaging applications. The UWB-MIMO antenna provides an isolation better than −20 dB in the entire UWB operating band.

用于高密度封装MIMO应用的单极极化分集天线

目的设计一种单元件双馈极化分集天线。拟议的天线工作在2.9至10.6 GHz，覆盖整个超宽带(UWB)频率范围。该天线设计用于大规模多输入多输出(MIMO)和封闭封装应用。设计/方法/方法天线尺寸为24 × 24 × 1.6 mm3。天线的辐射单元来源于Sierpinski-Knopp (SK)分形几何，以实现天线尺寸的小型化。天线在两个正交馈电之间有一个单一的反射短段，以提高隔离。结果:该天线系统具有S11 < - 10 dB, S21 < - 15 dB，在整个工作区域具有稳定的辐射特性。它还提供包络相关系数< 0.01，分集增益> 9.9 dB和容量损失< 0.4 bps/Hz。对模拟输出和实测输出进行了比较，发现结果是相似的。独创性/价值所提出的UWB-MIMO天线通过对辐射单元使用SK分形几何来显著减小尺寸。该天线采用双馈单辐射元件。存根位于天线元件之间，为高密度封装应用提供了紧凑和小型化的MIMO解决方案。UWB- mimo天线在整个UWB工作频带内的隔离度优于−20 dB。
