XHUMANA MANJE

I-Yagi Antenna iyi-antenna ecishiwe esiphethweni eyakhiwe i-oscillator esebenzayo (imvamisa i-oscillator egoqiwe), isibonisi sokwenziwa, kanye nabaqondisi abaningana abangenzi lutho abahlelwe ngokufana. Ngawo-1920, u-Hidetsugu Yagi kanye no-Taiki Uta base-Tohoku University e-Japan basungula lolu thi, olwaziwa ngokuthi "i-Yagi Uta Antenna" noma nje "i-Yagi Antenna".

Isici

1. Ukuqondisa okuqinile: I-antenna inokuqondisa okuhle futhi ingagxilisa amaza omsakazo ohlangothini oluthile. Izikhombisi-ndlela zemisebe eziphakeme ziyafana nezomqondisi, ezicindezela ngempumelelo imfuhlumfuhlu nokuphazamiseka eziqondisweni ezingaqondiwe.
2. Inzuzo ephakeme: Uma iqhathaniswa nezimpondo ze-dipole, i-antenna yophondo inenzuzo ephezulu futhi ingathwebula kangcono amasiginali akude, ithuthukise ikhwalithi yokwamukela nokucaca.
3. Isakhiwo esilula: sakhiwe ama-oscillator asebenzayo, i-passive reflectors, nabaqondisi abaningana abangenzi lutho abahlelwe ngokufana, isakhiwo silula uma kuqhathaniswa, izinto ezisetshenziswayo kulula ukuzithola, izindleko ziphansi, futhi azisindi, ziqinile, futhi kulula ukuzondla.

Isicelo

1. Inkundla yezokuxhumana: I-RF horn antenna esetshenziselwa ukuxhumana kwe-shortwave kanye ne-ultra shortwave, njengokuxhumana ngomsakazo ohamba ibanga elide, futhi ingasetshenziswa njengezinti zangaphandle zezikhulisi zamasignali kamakhalekhukhwini ukuze kuthuthukiswe amasignali omakhalekhukhwini. Ingakwazi ukunweba ububanzi bokuhlanganisa futhi ithuthukise amandla esignali kumanethiwekhi e-Wi Fi, afanele ukuxhuma izakhiwo ezikude noma ukwandisa ukumbozwa kwesilinganiso esikhulu.
2. Emkhakheni wokusakaza kanye nethelevishini, i-antenna ye-microwave horn ivame ukusetshenziswa njengethelevishini ethola i-antenna, engathola amasignali wethelevishini ngezindlela ezithile futhi ithuthukise umphumela wokwamukela.
3. Inkambu ye-radar: Ngenxa yokuqondisa nezici zayo zokuzuza, i-antenna yophondo lwe-millimeter wave ingasetshenziswa ukuthola okuqondiwe ezinhlelweni ze-radar.
4. Eminye imikhakha: I-Mm wave horn antenna nayo inezinhlelo zokusebenza embonini, ukutholwa kwedatha kanye nezinhlelo zokuqapha (i-SCADA), nezinjongo zesayensi nezokwelapha, njengokuxhumana okungenantambo phakathi kokutholwa kwedatha okukude kanye nemishini yokuqapha, kanye nokwamukela amasignali nokudlulisa kwezinye izivivinyo zesayensi.
I-Yagi antenna isetshenziswe kabanzi emikhakheni eminingi yokuxhumana engenantambo ngenxa yesakhiwo sayo esilula, izindleko zokukhiqiza eziphansi, kanye nokusebenza kahle.

QualwaveIzimpahla ze-Yagi Antenna zimboza ibanga lokuvama kufika ku-173MHz. Sinikeza izimpondo ezijwayelekile zokuzuza kwenzuzo engu-7dBi, kanye nezimpondo ezimbili ezenziwe ngezifiso ngokwezidingo zamakhasimende.
