基于脊间隙波导的圆极化缝隙天线研究的任务书 任务书 Title:ResearchonCircularlyPolarizedSlottedAntennaBasedonIntersticeWaveguide Background: Withtherapiddevelopmentofwirelesscommunicationtechnology,antennasplayanincreasinglyimportantroleinvariouscommunicationsystems,especiallyinmobilecommunicationsystems.Thecircularlypolarizedantennawithexcellentperformancehasbeengraduallyappliedinglobalpositioningsystem(GPS),satellitecommunication,andotherfields.Slottedantennasarewidelyusedincircularlypolarizedantennasduetotheirsimplestructure,highradiationefficiency,andbroadbandwidthcharacteristics.Andintersticewaveguideisacommonlyusedstructureinantennadesign,whichhastheadvantagesoflowloss,lowinterference,andeasyintegration. Objectives: Thisresearchaimstodesignandoptimizeacircularlypolarizedslottedantennabasedonintersticewaveguide.Thespecificobjectivesareasfollows: 1.Investigatetheprincipleandcharacteristicsofcircularlypolarizedantennasandintersticewaveguide. 2.Designaslottedantennabasedonintersticewaveguide,andoptimizeitsperformanceintermsofbandwidth,axialratio,andgain. 3.Evaluatetheperformanceofthedesignedantennathroughsimulationandmeasurement,andverifyitscircularlypolarizedcharacteristics. 4.Comparetheperformanceofthedesignedantennawithothercircularlypolarizedantennas,andanalyzeitsadvantagesandlimitations. Content: Thisresearchisdividedintothefollowingparts: 1.Literaturereview:Acomprehensivereviewoftherelatedresearchoncircularlypolarizedantennasandintersticewaveguidewillbeconducted,includingtheirprinciple,characteristics,design,andoptimization. 2.Antennadesign:Basedontheresearchoncircularlypolarizedantennasandintersticewaveguide,aslottedantennawillbedesignedandoptimized.Theoptimizationprocesswillfocusonimprovingthebandwidth,axialratio,andgainoftheantenna. 3.Simulationandmeasurement:Thedesignedantennawillbesimulatedusingacommercialelectromagneticsimulationsoftware,andthesimulationresultswillbecomparedwiththemeasurementresultstoevaluatetheperformanceoftheantenna. 4.Performanceanalysis:Theperformanceofthede
