Abstract

Inthispaper,the GlassFiberReinforcedPolymer(GFRP)compositesamplesareexploredinordertoevaluate their feasibility and adaptability for use in future metasurface antenna application. Multi-layer GFRP composite samples are fabricated with a proportionate ratio of resins and fiber usingVacuumAssistedResinTransferMolding(VARTM)technique.Ntypetowaveguide(WR-187)adapterspeciallydesignedforelectricalcharacterizationoftheseGFRPcompositesamplesisused. Thru-Reflect-Line (TRL) calibration technique is used for the test setup, and scattering parameters oftheseGFRPsamplesismeasuredbyusingthemanufacturedadapteralongwiththesampleholderonatwoportVectorNetworkAnalyzer(VNA).RelativepermittivityanddielectriclosstangentofGFRPcomposite samples are computed using Nicholson-Ross-Weir (NRW) and New Non-Iterativeconversionmethods.Thecomparativeanalysesofbothmethodsshowedaverygoodagreement betweenthem.TheGFRPsamplewiththelowestrelativepermittivityisshortlistedforitspossibleapplicationinfuturemetasurfaceantenna
