ABSTRACTIn this article, a wideband ceramic-based dual port MIMO (Multi Input Multi Output) antenna is investigated and analyzed. Wideband features are obtained with the assistance of asymmetrical dumbbell-shaped cylindrical ceramic. Triple-band circular polarized waves are also obtained with an S-shaped aperture having unequal strip length. Other special characteristic of the proposed MIMO radiator is to achieve bidirectional pattern diversity by placing radiators in opposite direction. Measured outcomes confirm that the proposed radiator offers a fractional bandwidth of 65.04% (4.02 to 7.89 GHz) with less than −25 dB mutual coupling between two identical ports. In between the three frequencies range, i.e., 4.75 to 5.02 GHz, 5.75 to 6.2 GHz, and 7.55 to 7.82 GHz, the value of axial ratio is well below the value of 3 dB. Measured far-field pattern and diversity parameters authorize the appropriateness of the proposed radiator in MIMO system.KEYWORDS: Circular polarizationDielectric Resonator Antenna (DRA)MIMO Antennapattern diversity AcknowledgmentsAuthor, Anand Sharma, wishes to acknowledge the Council of Science and Technology, UP, India, for giving the financial support to conduct this work successfully with notification No. CST/D-2396 dated 24/03/2021.Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThe work was supported by the Council of Science and Technology, U.P.

本文对一种基于陶瓷的宽带双端口MIMO(多输入多输出)天线进行了研究和分析。借助非对称哑铃形圆柱陶瓷获得宽带特性。采用不等长s型孔径也可得到三波段圆偏振波。所提出的MIMO散热器的另一个特殊特性是通过在相反方向放置散热器来实现双向方向分集。测量结果证实，所提出的散热器提供65.04%(4.02至7.89 GHz)的分数带宽，两个相同端口之间的互耦小于- 25 dB。在4.75 ~ 5.02 GHz、5.75 ~ 6.2 GHz和7.55 ~ 7.82 GHz三个频率范围内，轴比值远低于3db。测量的远场方向图和分集参数验证了所提出的辐射器在MIMO系统中的适用性。关键词:圆极化介质谐振器天线(DRA)MIMO天线方向分集致谢作者Anand Sharma希望感谢印度北方邦科学技术委员会(Council of Science and Technology, UP, India)提供的资金支持，并以第5号通知成功开展了这项工作。CST/D-2396日期为2021年3月24日。披露声明作者未报告潜在的利益冲突。本研究得到了美国科学技术委员会的支持[CST/D-2396，日期为24/03/2021]。

ABSTRACTIn this paper, a broadband dual-polarized antenna array with stable radiation pattern is proposed for 5 G base station applications. The proposed antenna array consists of a 2 × 2planarantennaarray, four 2 × 2 circle patch parasitic structures and a metal reflector. Based on the principal of the FP (Fabry-Perot) antenna to achieve the stable radiation pattern, when the parasitic loading height meets the resonant height of the FP antenna, serious radiation pattern distortion in large reflector environment could be improved effectively. A prototype of the 2 × 2 broadband dual-polarized antenna array is designed and fabricated. The measured results show that the −10 dB bandwidth of the proposed broadband dual-polarized array is able to cover 3.23–5.06 GHz with high isolation which is greater than 25 dB over the entire operating band. The antenna elementsofthearrayarecapableofmaintainingstable radiation pattern throughout the operating frequency range. The HPBW (half-power beam-width) in the horizontal plane is effectively controlled at 67°±5°with a gain of 8.8 ± 0.5 dBi. Due to the stable radiation performance mentioned above, the proposed dual-polarized array can be applied to future 5 G and sub-6 G base station applications.KEYWORDS: Base station antennacross dipoledual-polarized MIMO arrayFifth-generation(5G)parasitic structurestable radiation pattern Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementThe authors confirm that the data supporting the findings of this study are available within the article.Additional informationFundingThis work was supported in part by the National Natural Science Foundation of China under Grant No. 62001074; in part by the Chongqing Technology Innovation and Application Development Project under Grant No.cstc2019jscx-msxmX0049; and in part funded by the National Key Laboratory of Science and Technology on vacuum electronics.
