A compact triple-band bandpass filter based on metamaterials-中国期刊网

摘要 Thispaperpresentsacompacttriple-bandbandpassfilterbasedonmetamaterials.Theminiaturizationisrealizedbytheprincipleofphasecompensationofmetamaterial.Comparedwiththeconventionalhalf-wavelengthfilter,themetamaterialfilterhasasmallsizeof10mm×10mm.Thetriple-bandbandpassfilterperformancehasbeenvalidatedbytheelectromagneticsimulationsoftwareofhighfrequencystructuresimulator(HFSS).Theresultsillustratethatthefilterisdesignedwithcenterfrequenciesof2.4GHz,5.1GHzand8.8GHz,bandwidthsofabout7.9%(2.31—2.50GHz),7.8%(5.0—5.4GHz)and7.4%(8.50—9.15GHz),respectively,anditshowsgoodbandpasscharacteristics.
