    Ukuphela Kwesiqondiso Samagagasi Amancane

    Ukuphela kwe-waveguide yosayizi omfushane kuyisakhiwo se-waveguide esakhelwe ngokukhethekile esinobukhulu obufushane, esisetshenziselwa ukumunca nokususa amandla ezimpawu ze-microwave ezinamandla aphansi, ngaleyo ndlela kufezwe ukusetshenziswa kwezibonakaliso ezingadingekile esiketheni. Umgomo wokuphela kwe-waveguide yosayizi omfushane usekelwe ezindleleni ezimbili: ukuzindla kanye nokumunca. Lapho isignali ye-microwave idlula ekupheleni kosayizi omfushane ku-waveguide, esinye isignali sizobukiswa sibuyele emthonjeni, kanti enye ingxenye yesignali izobuswa ukuphela kwe-waveguide. Ngokuklama nokukhetha okufanele, ukulahlekelwa kokuzindla kungancishiswa futhi ukulahlekelwa komunca kungakhuliswa.

    Izici:

    1. Ukuba nesakhiwo esilula.
    2. Usayizi omncane
    3. Izindleko zokukhiqiza eziphansi
    4. Inkomba yamagagasi amile inhle kakhulu.

    Isicelo:

    1. Ukulungisa nokuhlola isekethe: Imithwalo ye-waveguide encane ivame ukusetshenziswa ekulungiseni nokuhlola isekethe ye-microwave. Ngokuxhuma ukuphela kwe-waveguide ne-output port yesekethe ezohlolwa, ukubonakaliswa kwesignali kungavinjelwa, ngaleyo ndlela kuvikelwe izingxenye zesekethe ekulimaleni nokuqinisekisa imiphumela yokuhlola enembile nethembekile.
    2. Ukulinganiswa kwe-coefficient yokuzindla: Ngokulinganisa i-coefficient yokuzindla, ukusebenza okufana kwesekethe engaphansi kokuhlolwa kungahlolwa. Ukuphela kwe-waveguide yobude obufushane kungasetshenziswa njenge-standard reference terms, futhi uma kuqhathaniswa nesekethe engaphansi kokuhlolwa, ngokulinganisa ubukhali besignali ebonisiwe, i-coefficient yokuzindla ingabalwa futhi ukusebenza okufana kwesekethe kungahlaziywa.
    3. Ukulinganiswa komsindo: I-Waveguide Ende Emfushane Imithwalo nayo idlala indima ebalulekile ekulinganisweni komsindo. Ngokusebenzisa izici zayo zokumunca, amasignali omsindo angadliwa ngempumelelo, ngaleyo ndlela kuncishiswe ukuphazamiseka komsindo ngesikhathi sokulinganisa.
    Ukuhlolwa kwesistimu ye-Antenna ne-RF: Ekuhlolweni kwesistimu ye-antenna ne-RF, imithwalo ye-microwave ingasetshenziswa ukulingisa ukusetshenziswa kwamandla okungekho endaweni lapho i-antenna itholakala khona. Ngokuxhumanisa ukuphela kwe-antenna ne-port yokuphuma, ukusebenza kwe-antenna nesistimu kungahlolwa, kulinganiswe, futhi kulungiselelwe.

    I-QualwaveIhlinzeka nge-VSWR ephansi kanye nokuphela kwe-waveguide encane okumboza ububanzi bemvamisa engu-5.38 ~ 40GHz. Ukuphela kwe-waveguide kusetshenziswa kabanzi ezinhlelweni eziningi.
