Umuhengeri (cyangwa umurongo ngenderwaho) ni umurongo wohereza imiyoboro ikozwe neza. Nigikoresho cyo gukwirakwiza ingufu za electromagnetique (cyane cyane kohereza imiyoboro ya electromagnetique hamwe nuburebure bwumurongo kuri santimetero) Ibikoresho bisanzwe (cyane cyane byohereza imiyoboro ya electromagnetique hamwe nuburebure bwa santimetero).
Guhitamo ingano yurukiramende igomba gusuzuma ibintu bikurikira:
1. Ikibazo cya Waveguide ikibazo
Kugirango umenye neza ko imiyoboro ya electromagnetic mumurongo watanzwe ishobora gukwirakwira muburyo bumwe bwa TE10 murwego rwo hejuru, ubundi buryo bwo murwego rwohejuru bugomba gucibwa, hanyuma b
2. Ikibazo cyubushobozi bwa Waveguide
Iyo ukwirakwiza imbaraga zisabwa, umurongo wizuba ntushobora gucika. Kwiyongera muburyo bukwiye b birashobora kongera imbaraga zingufu, b rero igomba kuba nini ishoboka.
3. Kwiyongera kwa waveguide
Nyuma ya microwave inyuze mumurongo, twizere ko imbaraga zitazabura cyane. Kwiyongera b birashobora gutuma attenuation iba nto, b rero igomba kuba nini ishoboka.
Urebye ibintu bikurura, ubunini bwurukiramende rwurukiramende rwatoranijwe muri rusange nka:
a = 0.7λ, λ nuburebure bwumurongo wa TE10
b = (0.4-0.5) a
Ibyerekezo byinshi byurukiramende byateguwe hamwe nikigereranyo cya a: b = 2: 1, kizwi nkicyerekezo gisanzwe, kuburyo igipimo ntarengwa cyagutse cya 2: 1 gishobora kugerwaho, ni ukuvuga igipimo cyumuvuduko mwinshi hamwe no kugabanuka cyane inshuro ni 2: 1. Kugirango tunoze ubushobozi bwimbaraga, umurongo wogukoresha hamwe na b> a / 2 witwa umuyaga mwinshi; kugirango ugabanye ingano nuburemere, umurongo wa waveguide hamwe na b
Ikigereranyo ntarengwa cyagutse cyizunguruka gishobora gukwirakwiza ni 1.3601: 1, ni ukuvuga, ikigereranyo cyumuvuduko mwinshi wo murwego rumwe na interineti yo hasi cyane ni 1.3601: 1. Icyifuzo gisabwa cyo gukora kumurongo wurukiramende ni inshuro 30% hejuru yumurongo wo guhagarika na 5% munsi yuburyo bwa kabiri bwo hejuru bwo guhagarika. Izi ndangagaciro zisabwa zirinda gukwirakwiza inshuro kuri radiyo yo hasi no gukora multimode kumurongo mwinshi.
