QHAGAMSHELANA NGOKU

I-eriyali ye-Yagi sisiphelo esikhutshwa yi-eriyali eyenziwe yi-oscillator esebenzayo (ngokuqhelekileyo i-oscillator esongiweyo), isibonisi sokwenziwa, kunye nabalawuli abaliqela abangenzi nto abacwangciswe ngokufanayo. Ngeminyaka yoo-1920, uHidetsugu Yagi kunye noTaiki Uta beYunivesithi yaseTohoku eJapan baqulunqa le eriyali, eyaziwa ngokuba yi "Yagi Uta Antenna" okanye ngokulula "Yagi Antenna".

Uphawu

1. Umkhombandlela owomeleleyo: I-antenna inomkhombandlela olungileyo kwaye inokujolisa amaza erediyo kwicala elithile. Olona lwalathiso lwemitha luphezulu luyafana nolo lomlawuli, ecinezela ngokufanelekileyo i-clutter kunye nophazamiseko kwiindlela ekungajoliswanga kuzo.
2. Inzuzo ephezulu: Xa kuthelekiswa ne-antenna ye-dipole, i-antenna yophondo inenzuzo ephezulu kwaye ingabamba ngcono imiqondiso ekude, iphucula umgangatho wokwamkela kunye nokucaca.
3. Isakhiwo esilula: siqulunqwe ngee-oscillators ezisebenzayo, i-passive reflectors, kunye nabalawuli abaliqela be-passive abacwangciswe ngokuhambelanayo, isakhiwo silula, izixhobo zifumaneka lula, iindleko ziphantsi, kwaye zikhaphukhaphu, zomelele, kwaye kulula ukuzondla.

Isicelo

1. Indawo yonxibelelwano: I-eriyali ye-RF esetyenziselwa unxibelelwano lwamaza amafutshane kunye ne-ultra shortwave, njengonxibelelwano lomgama omde kanomathotholo, kwaye inokusetyenziswa njengee-eriyali zangaphandle kwizandisi zesandisi sefowuni ephathwayo ukomeleza imiqondiso yefowuni ephathwayo. Inokwandisa uluhlu lwe-coverage kunye nokuphucula amandla omqondiso kwiinethiwekhi ze-Wi Fi, ezifanelekileyo ukudibanisa izakhiwo ezikude okanye ukwandisa umthamo omkhulu.
2. Kwintsimi yosasazo kunye nomabonwakude, i-antenna ye-microwave i-antenna isoloko isetyenziswa njengomabonwakude ofumana i-eriyali, enokufumana iimpawu zikamabonwakude kwiindlela ezithile kunye nokuphucula umphumo wokwamkela.
3. Ibala le-radar: Ngenxa yolwalathiso lwayo kunye neempawu zokuzuza, i-antenna ye-antenna ye-wave wave i-millimeter ingasetyenziselwa ukufumanisa iinjongo kwiinkqubo ze-radar.
4. Eminye imimandla: I-antenna ye-antenna ye-wave ye-Mm nayo inezicelo kwi-industry, ukufumana idatha kunye neenkqubo zokubeka iliso (i-SCADA), kunye neenjongo zesayensi kunye nezonyango, ezifana nonxibelelwano olungenacingo phakathi kokufunyanwa kwedatha ekude kunye nezixhobo zokubeka iliso, kunye nokwamkelwa komqondiso kunye nokuhanjiswa kwezinye iimvavanyo zesayensi.
I-antenna ye-Yagi isetyenziswe ngokubanzi kwiindawo ezininzi zonxibelelwano ezingenazingcingo ngenxa yesakhiwo sayo esilula, ixabiso eliphantsi lokuvelisa, kunye nokusebenza kakuhle.

QualwaveUkubonelela ngee-Antennas zeYagi zigubungela uluhlu lwamaza ukuya kuthi ga kwi-173MHz. Sinikezela ngee-eriyali zophondo lokuzuza umgangatho wenzuzo ye-7dBi, kunye nee-eriyali ezilungelelanisiweyo eziphindwe kabini zophondo ngokweemfuno zabathengi.
