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.

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.

ABSTRACTThis paper presents a novel design for a low-profile Fabry–Perot resonator antenna (FPRA) that operates at two distinct frequency bands using a single partially reflecting surface (PRS). The PRS is composed of two different types of unit cells arranged in a staggered fashion. These unit cells are comprised of double-sided complementary structures, including a square patch with a square aperture and a circular ring with a circular ring slot. To reduce the overall profile of the antenna, an artificial magnetic conductor (AMC) surface is utilized as the reflection plane. The proposed design employs a dual-band slotted patch antenna as the primary source. The overall dimensions of the FPRA are 91 mm×91 mm×5.54 mm. The performance of the prototype antenna is validated through measurement, demonstrating peak gains of 14.1 and 16.1 dBi at frequencies of 6.65 and 12.05 GHz, respectively. Additionally, the antenna exhibits −10 dB impedance bandwidths of 6.5–6.8 GHz and 12.15–12.23 GHz at the two frequency bands.KEYWORDS: Dual-bandFabry–Perotlow-profilepartially reflecting surface Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThe work was supported by the National Natural Science Foundation of China [62071282]; Open Foundation of China-Belarus Belt and Road Joint Laboratory on Electromagnetic Environment Effect [ZBKF2022020102].

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.

ABSTRACTIn this work, an ultra-wideband coding phase gradient metasurface (CPGM) is proposed for radar cross section (RCS) reduction. The design process is presented in detail, in which eight types of coding elements are proposed firstly by using Pancharatnam-Berry (P-B) phase. The eight types of coding elements have different reflection direction or phase response under the same EM-wave incidence for they can introduce a series of phase gradients with different directions or starting-values under both right-handed and left-handed circular-polarized incidences, so the proposed CPGM composed of these coding elements has excellent performance in RCS reduction. The simulated results show that, compared with a pure metallic plate with the same size, the RCS of the CPGM can be reduced more than 10 dB in the ultra-wide frequency band of 9.2–46.2 GHz under normal incidence with arbitrary polarization, the relative bandwidth is up to 133.6%; moreover, the RCS reduction under oblique incidence with arbitrary polarization can still be kept larger than 9.3 dB in the frequency band of 13.1–42.5 GHz when the incident angle is increased to 45°. Finally, one experiment is carried out, a reasonable agreement exists between the simulated and experimental results.KEYWORDS: metasurfacePancharatnam-Berry phaseRadar cross section (RCS) AcknowledgmentsThis work was supported by the National Natural Science Foundation of China (Grant No. 62072378) and High Level Talent Special Fund of Xijing University (Program No. XJ21B05).Disclosure statementNo potential conflict of interest was reported by the authors.Additional informationFundingThis work was supported by the National Natural Science Foundation of China [62072378].

ABSTRACTA broadband low profile magneto-electric dipole (ME-dipole) antenna is proposed which can control the steering of the antenna beam in the elevation plane and azimuth plane. A reflective phase gradient metasurface (RPGMS) is designed to act as the partially reflecting surface of the antenna and provides two different phase shifts for it. By rotating and translating RPGMS around the center of the antenna can reshape the wavefront shape, realize beam steering with directions (θ, ϕ)= (±40°, 0°), (±30°, 0°), (±20°, 0°), (±20°, 90°). The results of full wave simulation are in good agreement with the measured results, the beam tilted range of ± 40° in E-plane and ± 20° in H-plane are obtained at 8 GHz. The bandwidth is between 42.5% and 48.4%, with a maximum gain of 6.29dBi.KEYWORDS: Antennabeam controlbroadbandmetasurface Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by the National Natural Science Foundation of China under project number 61701278.

The bandwidth is between 42.5% and 48.4%, with a maximum gain of 6.29dBi.KEYWORDS: Antennabeam controlbroadbandmetasurface Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by the National Natural Science Foundation of China under project number 61701278.","PeriodicalId":50542,"journal":{"name":"Electromagnetics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135858504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
