Abstract:

Accordingtothedual-modecouplingtheory,dual-moderesonatorsareconstructedbyintroducingmetallizedviasandcouplinggapsbasedontheoriginalsquarecoaxialfrequencyselectivesurface(FSS).Twoindependenttransmissionpolesarerealizedthroughtheoddandevenmodescouplingsofdual-moderesonators,resultinginflatbandpassperformances.Inaddition,multipletransmissionzerosareobtainedbecauseofthereflectioninpaths,andout-of-phasecounteractionbetweenpathsthusthefrequencyselectivityisimprovedgreatly.Therefore,abandpassFSSwithwideout-of-bandrejectionandadual-bandbandpassFSSareproposed.Byusingprintedcircuitboard(PCB)technology,theproposedFSSshavefabricatedandmeasured,andgoodagreementscanbeobservedbetweenthesimulationsandmeasurements.ThemeasuredresultsshowthattheproposedFSSsexhibitstableresponseandhighfrequencyselectivityfordifferentpolarizationsandincidentangles.
