Innovative designs and performance evaluation of super wideband MIMO antennas: a survey
Source abstract
Abstract
Multiple Input Multiple Output (MIMO) antenna technology plays a crucial role in enhancing the performance of modern wireless communication systems. This survey explores the latest advancements in MIMO antenna design and focuses on innovations that improve performance metrics such as isolation, bandwidth, gain, and efficiency. The paper reviews various antennas: wideband, compact, tri-polarised, ultra-wideband (UWB), super-wideband (SWB), and multi-band antennas. It highlights significant advancements in antenna design, such as developing novel feeding structures, using Characteristic Mode Analysis (CMA) to optimise performance, and integrating Electromagnetic Band Gap (EBG) structures for improved isolation. Decoupling techniques are also discussed to minimise mutual coupling between elements. The evolution of SWB-MIMO antennas has been key in achieving high isolation, wide bandwidths, and low envelope correlation coefficients (ECC), essential for applications such as 5 G, IoT, and UWB systems. This paper consolidates a broad spectrum of research on MIMO antenna technologies and presents emerging trends aimed at improving system efficiency and reducing interference. Key innovations discussed include fractal designs, multi-band functionality, and flexible antenna materials, representing the forefront of MIMO antenna development for future communication systems.
