Abstract

ABSTRACTA hybrid dielectric resonator antenna (DRA) array is proposed for the wideband millimeter-wave communication. The radiator is composed with a pair of stacked dielectric resonators (DRs), which are H-shaped and Hexagon-shaped DRs, respectively. The dual-slots on the substrate integrated waveguide (SIW) cavity are utilized for higher mode generation in the DRA element. The antenna bandwidth is improved by the stacked DRs and dual-slot feeding. The structural characteristics and key parameters of feeding slots are discussed in detail. The DRA array fed with parallel power distribution feeding network is fabricated and measured to verify the reliability of the simulations, and the simulations and measurements have reasonable consistency. The impedance bandwidth is from 23.55 GHz to 27.28 GHz (14.7%), and the measured gain ranges from 13.1 dBi to 15.7 dBi. The radiation patterns are stable in the operation band. The proposed DRA array has a promising application prospect for 5 G communication system.KEYWORDS: Dielectric resonator antennadual-slotsmillimeter-wavestacked structure AcknowledgmentsThis work was funded by China Postdoctoral Science Foundation under grant number 2022MD723726.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 informationFundingThe work was supported by the China Postdoctoral Science Foundation [2022MD723726].

双槽馈电的宽带毫米波混合介质谐振器天线阵列

摘要提出了一种用于宽带毫米波通信的混合介质谐振器天线(DRA)阵列。该散热器由一对叠置介质谐振器组成，分别为h型和六边形介质谐振器。基板集成波导(SIW)腔上的双槽在DRA元件中用于更高的模式生成。通过堆叠dr和双槽馈电，提高了天线带宽。详细讨论了进给槽的结构特点和关键参数。制作并测量了并联配电馈电网络馈电DRA阵列，验证了仿真的可靠性，仿真结果与实测结果具有合理的一致性。阻抗带宽为23.55 GHz ~ 27.28 GHz(14.7%)，测量增益范围为13.1 dBi ~ 15.7 dBi。辐射模式在工作波段是稳定的。该阵列在5g通信系统中具有广阔的应用前景。本文由中国博士后科学基金资助，资助号:2022MD723726。披露声明作者未报告潜在的利益冲突。数据可用性声明作者确认在文章中可以获得支持本研究结果的数据。本研究得到中国博士后科学基金资助[2022MD723726]。

期刊介绍： Publishing eight times per year, Electromagnetics offers refereed papers that span the entire broad field of electromagnetics and serves as an exceptional reference source of permanent archival value. Included in this wide ranging scope of materials are developments in electromagnetic theory, high frequency techniques, antennas and randomes, arrays, numerical techniques, scattering and diffraction, materials, and printed circuits. The journal also serves as a forum for deliberations on innovations in the field. Additionally, special issues give more in-depth coverage to topics of immediate importance. All submitted manuscripts are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. Submissions can be made via email or postal mail.
