基于ADS的阵列天线的研究与设计

目录基于ADS的阵列天线的研究与设计目录中文摘要 第五章总结与展望随着通信技术的迅速发展，阵列天线技术被广泛的应用在各种无线通信系统中，阵列天线的性能直接影响着通信系统的效果。由于阵列天线具有高增益、高功率、低旁瓣、波束控制等优点，具有广阔的应用前景。但是在阵列天线中，互耦效应会恶化阵列天线的性能，因此研究阵列天线必须要研究解耦技术。本文基于ADS，对单频阵列天线，双频阵列天线和宽带阵列天线分别进行了研究和设计，设计的天线结构简单、易于集成且性能良好。本文的具体工作如下：1.设计了一种基于ADS的单频缝隙阵列天线。在接地板上刻蚀弯折形缝隙产生2.4GHz处的谐振。ADS由四组金属反射贴片组成，用来降低单元间的互耦。结果表明天线的工作带宽包含WLAN的2.4-2.484GHz工作频段，单元之间的隔离度大于15dB，天线具有良好的辐射特性。2.设计了一种基于ADS的双频单极子阵列天线。天线的辐射单元由两个弧形条带组成，较长的弧形条带产生一个低频谐振，较短的弧形条带产生一个高频谐振。ADS由四组金属条带组成，较长的金属条带降低低频处的互耦，较短的金属条带降低高频处的互耦。结果表明天线的工作带宽包含WLAN的2.4-2.484GHz和5.15-5.35GHz工作频段，单元间的隔离度大于15dB，天线具有良好的辐射特性。3.设计了一种基于ADS的宽带单极子阵列天线。天线的辐射单元是一个圆形贴片，采用缺陷地结构改善高频时的方向图。ADS由四组不同长度的金属条带组成，用来降低单元间的互耦。结果表明天线的工作带宽包含WLAN和WiMAX的所有工作频段，单元间的隔离度大于15dB，天线具有良好的辐射特性。针对本文设计的三种基于ADS的阵列天线，由于时间和个人能力的限制，存在以下不足和需要改进的地方：在双频单极子阵列天线和宽带单极子阵列天线的设计中，ADS对天线的辐射方向图影响较大，下一步需要寻找方法减小对方向图的影响。参考文献参考文献参考文献侯甲，微带平面阵列天线的设计，西安：西安电子科技大学硕士论文，2014.樊文君，5G背景下阵列天线的研究与设计，南京：南京邮电大学硕士论文，2019.郭华，阵列天线综合及子阵列划分的研究，西安：西北工业大学博士论文，2015.孙学平，阵列天线优化及其宽角扫描技术研究，西安：西安电子科技大学硕士论文，2019.孙晓佳，耦合馈电微带阵列天线设计，西安：西安电子科技大学硕士论文，2019.G.H.Sun,S.W.WongandH.Wong.ABroadbandAntennaArrayUsingFull-WaveDipole.IEEEAccess,2017,5,13054-13061.R.N.Lian,Z.D.Wang,Y.Z.Yin,J.J.WuandX.Y.Song.DesignofaLow-ProfileDual-PolarizedSteppedSlotAntennaArrayforBaseStation.IEEEAntennasWirelessPropag.Lett.,2015,15,362-365.G.W.Yang,J.YLi,D.J.WeiandR.Xu.StudyonWide-AngleScanningLinearPhasedArrayAntenna.IEEETrans.AntennasPropagat.,2018,66(1),450-455.S.AfoakwaandY.B.Jung.WidebandMicrostripComb-LineLinearArrayAntennaUsingStubbed-ElementTechniqueforHighSidelobeSuppression.IEEETrans.AntennasPropagat.,2017,65(10),5190-5199.饶佳人，阵列天线互耦特性研究，南京：南京航空航天大学硕士论文，2013.齐宏业，天线互耦表征及去耦方法的研究，南京：东南大学博士论文，2016.钮历宇，多天线互耦效应对MIMO系统性能的影响，南京：南京邮电大学硕士论文，2013.P.N.Fletcher,M.DeanandA.R.Nix.MutualcouplinginmultielementarrayantennasanditsinfluenceonMIMOchannelcapacity.Electron.Lett,2003,39(4),342-344.B.N.GetuandR.Janaswamy.TheeffectofmutualcouplingonthecapacityoftheMIMOcube.IEEEAntennasWirelessPropag.Lett.,2005,4,240-244.J.GuptaandA.A.Ksienski.Effectofmutualcouplingontheperformanceofadaptivearrays.IEEETrans.AntennasPropagat.,1983,5,785-791.E.M.FrielandK.M.Pasala.EffectsofmutualcouplingontheperformanceofSTAPantennaarrays.IEEETransactionsonAerospaceandElectronicSystems,2000,36(2),518-527.S.KimandS.Nam.ACompactandWidebandLinearArrayAntennaWithLowMutualCoupling.IEEETrans.AntennasPropagat.,2019,67(8),5695-5699.D.CaratelliG.Toso,O.V.StukachandN.V.Panokin.DeterministicConstrainedSynthesisTechniqueforConformalAperiodicLinearAntennaArrays—PartII:Applications.IEEETrans.AntennasPropagat.,2019,67(9),5962-5973.M.Karaboikis,C.Soras,G.TsachtsirisandMakios.Compactdual-printedinverted-Fantennadiversitysystemsforportablewirelessdevices.IEEEAntennasWirelessPropag.Lett.,2004,3,9-14.M.I.Ahmed,A.Sebak,E.A.AbdallahandH.Elhennawy.Mutualcouplingreductionusingdefectedgroundstructure(DGS)forarrayapplications.AntennaTechnologyandAppliedElectromagnetics(ANTEM),2012.A.M.M.AAllamandA.M.G.Hemdan.NovelDGSShapeforMutualCouplingReduction.2016GermanMicrowaveConference(GeMiC),2016.T.Q.Jiao,T.JiangandY.S.Li.Alowmutualcouplingantennaarrayusingalternating-directionS-shapeddefectedgroundstructures.2016IEEE5thAsia-PacificConferenceonAntennasandPropagation(APCAP),2016.R.L.Shao,Y.J.Zhou,L.Yang,Y.J.ZhouandC.Tan.Compactmeander-slotDGSforMIMOantennawithhighisolation.2018InternationalWorkshoponAntennaTechnology(iWAT),2018.S.NandandA.Mohan.ACompactDual-BandMIMOSlotAntennaforWLANApplications.IEEEAntennasWirelessPropag.Lett.,2017,16,2457-2460.赵加贝，小型化低耦合MIMO天线的设计，成都：电子科技大学硕士论文，2016.L.Zhao,L.K.YeungandK.L.Wu.Acoupledresonatordecouplingnetworkfortwo-elementcompactantennaarraysinmobileterminals.IEEETrans.AntennasPropagat.,2014,62(5),2767-2776.L.Y.ZhaoandK.L.Wu.Adual-bandcoupledresonatordecouplingnetworkfortwocoupledantennas.IEEETransonAntennasPropag.,2015,63(7),2843-2850.R.L.Xia,S.W.Qu,P.F.Li,Q.JiangandZ.P.Nie.AnEfficientDecouplingFeedingNetworkforMicrostripAntennaArray.IEEEAntennasWirelessPropag.Lett.,2015,14,871-874.杨子贤，无线通信系统中小型化MIMO天线的研究与设计，成都：电子科技大学博士论文，2016.Y.F.LuandY.C.Lin.Electromagneticband-gapbasedcorrugatedstructuresforreducingmutualcouplingofcompact60GHzcavity-backedantennaarraysinlowtemperatureco-firedceramics.IETMicrow.AntennasPropag.,2013,7(9),754-759.N.MaandH.l.Zhao.ReductionofthemutualcouplingbetweenaperturecoupledmicrostrippatchantennasusingEBGstructure.2014IEEEInternationalWirelessSymposium,2014.X.Yang,Y.Liu,Y.X.XuandS.X.Gong.IsolationEnhancementinPatchAntennaArrayWithFractalUC-EBGStructureandCrossSlot.IEEEAntennasWirelessPropag.Lett.,2016,16,2175-2178.Q.Li,A.P.Feresidis,M.MavridouandP.S.Hall.MiniaturizedDouble-LayerEBGStructuresforBroadbandMutualCouplingReductionBetweenUWBMonopoles.IEEETrans.AntennasPropagat.,2015,63(3),1168-1171.X.C.Jiang,H.X.WangandT.Jiang.AlowmutualcouplingMIMOantennausingEBGstructures.2017ProgressInElectromagneticsResearchSymposium-Spring(PIERS),2017.W.W.Han,X.P.Zhou,J.Ouyang,Y.Li,R.LongandFengYang.Asix-portMIMOantennasystemwithhighisolationfor5-GHzWLANaccesspoints.IEEEAntennasWirelessPropag.Lett.,2014,13,880-883.H.Y.Qi,X.X.Yin,H.X.Zhaoand
