    I-waveguide loop coupler iyidivayisi ye-microwave equkethe i-loop waveguide kanye nemigqa emibili yokudlulisela.

    Lesi sixhumi se-microwave esiqondisa i-single directional loop sisetshenziswa kakhulu ekuhlanganiseni i-bandpass filteloop kanye nokulinganisa i-impedance ye-short-circuit yemigqa yokudlulisa. Lesi sixhumi singadlulisela amandla avame kakhulu kusuka komunye umugqa wokudlulisa siye komunye, ngaleyo ndlela sifinyelele ukuhlanganiswa kwe-beam.

    Umgomo wokusebenza we-waveguide loop coupler uncike kakhulu ezicini ezimbili: izici zokudlulisela ze-loop coupler kanye nomugqa we-microstrip. I-directional coupler ibhekisela kusihlukanisi samandla esinokuqondisa.

    I-loop coupler iyisici esibalulekile kuma-waveguide loop coupler, okudlala indima enkulu ekuhlanganiseni kwamandla.

    Lokhu kuhlanganiswa kwe-annular kuqukethe izihibe ezimbili eziseduze, kanye nengxenye eyodwa ye-loop esebenza njenge-port yokufaka kanti enye ingxenye ye-loop isebenza njenge-port yokuphuma. Lapho isignali yemvamisa ephezulu ifika ku-annular coupling eduze kwe-port yokufaka, izodluliselwa ku-half loop eseduze. Kuleli qophelo, ngenxa yokuba khona kwensimu yamagnetic, isignali izodluliselwa nakwenye ingxenye ye-loop, ngaleyo ndlela kufezwe ukuhlanganiswa kwamandla. Ekugcineni, kungenzeka ukuhlanganisa isignali yokufaka kusuka ku-port yokufaka kuya ku-output port ngenkathi uhlanganisa izinga eliphezulu lokusebenza kahle kokuhlanganisa.

    Izinkomba zokusebenza eziyinhloko zama-couplers e-broadband single directional loop

    Izinkomba zokusebenza eziyinhloko zama-measuloop directional couplers zifaka phakathi ububanzi bemvamisa yokusebenza, izinga lokuxhumanisa (noma ukunciphisa ukuguquguquka), ukuqondiswa, kanye nesilinganiso segagasi lokuma lokufaka/lokukhipha.
    1. Izinga lokuhlanganisa libhekisela kusilinganiso se-decibel samandla okufaka we-waveguide eyinhloko kumandla okukhipha echwebeni lokuhlanganisa ngaphansi kwesimo somthwalo ohambisanayo echwebeni ngalinye.
    2. Ukuqondiswa kubhekisela kusilinganiso se-decibel samandla okukhipha echwebeni lokuxhumanisa namandla okukhipha echwebeni lokuhlukanisa ngaphansi kwesimo somthwalo ohambisanayo echwebeni ngalinye. Ama-couplers aqondisayo asetshenziswa kabanzi ekuthathweni kwesampula yesiginali ekusatshalalisweni kwamandla kanye nokulinganiswa kwe-microwave.

    I-Qualwaveinikeza ama-broadband kanye nama-single directional loop coupler anamandla aphezulu kusukela ku-2.6 kuya ku-18GHz. Ama-coupler asetshenziswa kabanzi ezinhlelweni eziningi.
