XHUMANA MANJE

I-Yagi Antenna iyi-antenna ecishiwe ekugcineni eyakhiwe yi-oscillator esebenzayo (ngokuvamile i-oscillator egoqiwe), i-reflector engasebenzi, kanye nabaqondisi abaningana abangasebenzi abahlelwe ngasikhathi sinye. Ngawo-1920, uHidetsugu Yagi noTaiki Uta baseNyuvesi yaseTohoku eJapan basungula le-antenna, eyaziwa ngokuthi "i-Yagi Uta Antenna" noma nje "i-Yagi Antenna".

Isici

1. Ukuqondisa okuqinile: I-Antenna inesiqondiso esihle futhi ingagxila amagagasi omsakazo ohlangothini oluthile. Ukuqondisa okuphezulu kwemisebe kufana nokwemqondisi, okuvimbela ngempumelelo ukuxinana nokuphazamiseka eziqondisweni ezingezona eziqondiwe.
2. Inzuzo ephezulu: Uma kuqhathaniswa nama-antenna e-dipole, i-antenna ye-horn inenzuzo ephezulu futhi ingabamba kangcono amasignali akude, ithuthukise ikhwalithi yokwamukela kanye nokucaca.
3. Isakhiwo esilula: sakhiwe ngama-oscillator asebenzayo, ama-reflector angasebenzi, kanye nabaqondisi abaningana abangasebenzi abahlelwe ngasikhathi sinye, isakhiwo silula kakhulu, izinto zokwakha kulula ukuzithola, izindleko ziphansi, futhi silula, siqinile, futhi kulula ukusiphakela.

Isicelo

1. Inkambu yokuxhumana: I-antenna ye-RF horn esetshenziselwa ukuxhumana nge-shortwave kanye ne-ultra shortwave, njengokuxhumana ngomsakazo okude, futhi ingasetshenziswa njenge-antenna yangaphandle yama-amplifier esignali yocingo ukuze kuthuthukiswe amasignali ocingo. Ingandisa ububanzi bokumbozwa futhi ithuthukise amandla esignali kumanethiwekhi e-Wi Fi, afanele ukuxhuma izakhiwo ezikude noma ukwandisa ukumbozwa okukhulu.
2. Emkhakheni wokusakaza kanye nethelevishini, i-antenna ye-microwave horn ivame ukusetshenziswa njenge-antenna yokwamukela ithelevishini, engathola izimpawu zethelevishini ngezindlela ezithile futhi ithuthukise umphumela wokwamukela.
3. Insimu ye-radar: Ngenxa yezimpawu zayo zokuqondisa kanye nokuthola, i-antenna ye-millimeter wave horn ingasetshenziswa ukuthola ama-target ezinhlelweni ze-radar.
4. Eminye imikhakha: I-antenna ye-Mm wave horn nayo inezinhlelo zokusebenza embonini, izinhlelo zokuthola idatha kanye nokuqapha (i-SCADA), kanye nezinjongo zesayensi nezokwelapha, njengokuxhumana okungenantambo phakathi kokuthola idatha okude kanye nemishini yokuqapha, kanye nokwamukela kanye nokudlulisa isignali kwezinye izivivinyo zesayensi.
I-antenna ye-Yagi isetshenziswe kabanzi emikhakheni eminingi yokuxhumana okungenantambo ngenxa yesakhiwo sayo esilula, izindleko zokukhiqiza eziphansi, kanye nokusebenza okuhle.

I-QualwaveIzinsiza ze-Yagi Antennas zimboza ububanzi bemvamisa efika ku-173MHz. Sinikeza ama-antenna ajwayelekile e-gain horn e-gain 7dBi, kanye nama-antenna e-dual polarized horn aklanyelwe wena ngokwezidingo zamakhasimende.
