The design uses the triangular-shape quarter-mode substrate integrated waveguide (QMSIW) cavity loaded with a complementary split-ring resonator. The compact cavity shows a resonant mode below the quasi-TE<inf>1,0,0.5</inf> mode of an original QMSIW cavity, which indicates a further size reduction. In addition, its low quality factor (Q) is useful for BPFs with broad fractional bandwidth (FBW). A surface micromachined two-pole Chebyshev BPF is realized for operation at 35 GHz with a 20 dB return loss FBW of 8% and an insertion loss of 1.7 dB. © 2015 Wiley Periodicals, Inc.Recurso electrónicoapplication/pdfenghttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/article10.1002/mop.29190Bandpass filterComplementary split ring resonatorLiquid crystal polymerMillimetre-waveQuarter-mode substrate integrated waveguideBandpass filtersBandwidthCopolymersFrequency responseLiquid crystal polymersLiquid crystalsMicrowave circuitsMillimeter wavesOptical resonatorsPolesResonatorsRing gagesSubstrate integrated waveguidesSubstratesWaveguidesWireless telecommunication systemsBandpass filter (BPF)Complementary split ring resonatorsFractional bandwidthsMillimeter-wave bandpass filtersMillimetre wavesSize reductionsTriangular shapesWireless applicationWaveguide filtersinfo:eu-repo/semantics/restrictedAccessAtribución-NoComercial 4.0 InternacionalUniversidad Tecnológica de BolívarRepositorio UTB36698427600562975607007402126778
