Abstract

This letter presents the design and analysis of an ultrawideband (UWB) artificial magnetic conductor (AMC) aimed to enhance the gain of a UWB millimeter-wave (mm-wave) multiple-input–multiple-output (MIMO) antenna. The AMC features capacitive slots to excite TM20 mode to achieve a phase bandwidth of 14.08 GHz, ranging from 23.49 GHz to 37.57 GHz. A 10 × 10 AMC array is positioned 0.38λ₀ (λ₀ is free-space wavelength at 23.27) beneath the MIMO antenna for the gain enhancement. The proposed antenna resonates from 23.27 GHz to 39.3 GHz with an impedance bandwidth of 16.03 GHz. The isolation between quad ports is greater than 19.84 dB. The enhanced gain of the proposed MIMO antenna ranges from 8.7 dBi to 12.21 dBi, with maximum gain reaching 12.21 dBi at 31.5 GHz. The proposed antenna shows diverse performance in terms of envelope correlation coefficient < 0.005, channel capacity loss < 0.26 b/s/Hz, and total active reflection coefficient < −10 dB. The size of the proposed antenna is 3.8λ₀ × 3.8λ₀ × 0.38λ₀ only. This makes the proposed antenna suitable for a 5G bastion antenna.

基于超宽带AMC的毫米波MIMO天线设计与分析

本文介绍了一种超宽带（UWB）人工磁导体（AMC）的设计和分析，旨在提高超宽带毫米波（mm-wave）多输入多输出（MIMO）天线的增益。AMC具有电容槽，可激发TM20模式，实现14.08 GHz的相位带宽，范围从23.49 GHz到37.57 GHz。在MIMO天线下方0.38λ0 （λ0为自由空间波长为23.27）处放置10 × 10的AMC阵列以增强增益。该天线谐振范围为23.27 GHz ~ 39.3 GHz，阻抗带宽为16.03 GHz。四口间隔离度大于19.84 dB。MIMO天线增强增益范围为8.7 ~ 12.21 dBi，在31.5 GHz时最大增益达到12.21 dBi。该天线在包络相关系数< 0.005、信道容量损耗< 0.26 b/s/Hz、总主动反射系数<−10 dB等方面表现出不同的性能。天线尺寸仅为3.8λ0 × 3.8λ0 × 0.38λ0。这使得该天线适用于5G堡垒天线。

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
