Njengenye yezindlela zokuphakela zama-waveguide antenna, idizayini ye-microstrip to waveguide idlala indima ebalulekile ekudluliselweni kwamandla.Imodeli yendabuko ye-microstrip to waveguide imi kanje.I-probe ephethe i-substrate ye-dielectric futhi ephakelwa umugqa we-microstrip ifakwa esikhaleni sodonga olubanzi lwe-waveguide engunxande.Ibanga phakathi kwe-probe nodonga lwesiyingi esifushane ekugcineni kwe-waveguide cishe liphindwe kane kunobude begagasi obusebenzayo.ingxenye eyodwa.Ngaphansi kwesisekelo sokukhetha i-dielectric substrate, ukusabela kwe-probe kuncike kusayizi womugqa we-microstrip, futhi ukusabela kwe-waveguide ye-short-circuit kuncike endaweni yodonga olufushane.Lawa mapharamitha athuthukiswe ngokuphelele ukuze kufinyelelwe ukufaniswa kwe-impedance kwama-resistors ahlanzekile futhi kuncishiswe ukudluliswa kokulahlekelwa kwamandla.
I-Microstrip kusakhiwo se-waveguide ngemibono ehlukene
Imikhiqizo yochungechunge lwe-RFMISO Microstrip Antenna:
I-RM-MA25527-22
I-RM-MA425435-22
Icala
Ngokwemibono yokuklama enikezwe ezincwadini, klama i-waveguide to microstrip converter enomkhawulokudonsa osebenzayo we-40~80GHz.Amamodeli avela emibonweni ehlukene ami kanje.Njengesibonelo esivamile, kusetshenziswa i-waveguide engajwayelekile.Ugqinsi kanye ne-dielectric engaguquki yezinto ze-dielectric zisekelwe kuzici ze-impedance ze-microstrip probe zalungiswa.
Izinto eziyisisekelo: i-dielectric njalo 3.0, ukujiya 0.127mm
Usayizi we-Waveguide a*b: 3.92mm*1.96mm
Usayizi wegebe odongeni olubanzi ngu-1.08 * 0.268, futhi ibanga elisuka odongeni olufushane liyi-0.98.Bona isibalo samapharamitha ka-S nezici ze-impedance.
Ukubuka phambili
Ukubuka ngemuva
Amapharamitha we-S: 40G-80G
Ukulahlekelwa kokufaka ebangeni lokudlula kungaphansi kuka-1.5dB.
Izici ze-Port impedance
I-Zref1: I-impedance yokufaka yomugqa we-microstrip yi-50 ohms, i-Zref1: I-impedance ye-wave ku-waveguide cishe i-377.5 ohms;
Amapharamitha angathuthukiswa: ukujula kokufakwa kwe-probe D, usayizi W*L kanye nobude begebe elisuka odongeni lwesiyingi esifushane.Ngokusho kwephoyinti le-centre frequency point 45G, i-dielectric constant ingu-3.0, i-wavelength elinganayo ingu-3.949mm, kanti i-wavelength elingana nekota eyodwa icishe ibe ngu-0.96mm.Uma isisondele ekufaniseni okumsulwa kokumelana, i-waveguide isebenza kumodi eyinhloko ye-TE10, njengoba kuboniswe ekusabalaliseni insimu kagesi kumfanekiso ongezansi.
