Nxibelelana ngoku

I-YAGI Antenna sisiphelo se-entenna esenziwe nge-oscillator esebenzayo (ngesiqhelo i-oscillator esongelweyo), umboniso we-oscillator onesidima, kwaye abalawuli abadlulayo bacwangcise ngokuhambelana. Ngeminyaka yee-1920, i-HidSsugu Yagi naseTaiki Usuka kwiYunivesithi yaseTooki eJapan yafaka le ntshona, eyaziwa ngokuba yi "YAGI i-antenna" okanye nje ".

Phawula

1. Isalathiso esomeleleyo: I-Antentena inolwando oluhle kwaye inokugxila kumaza erediyo kwicala elithile. Eyona ndlela iphambili ye-radiation ye-radiation iyafana nelo loMlawuli, ngokunyanzelisa ukucinezela i-clutter kunye nokuphazamiseka kwiimpawu ezingabizi zimpawu.
2. Inzuzo ephezulu: xa kuthelekiswa ne-dipole e-antentenas, i-hinn e-wintenna inenzuzo ephezulu kwaye inokufumana imiqondiso ekude, ukuphucula umgangatho wokwamkela kunye nokucaciswa.
3. Ulwakhiwo olulula: Ukudityaniswa kwee-oscillators ezisebenzayo, abo babonisa abakhoyo abahambayo, kwaye abalawuli abaninzi abahamba bacwangciswe ngokuhambelana, i-SOFT ilula ukuyifumana, kwaye iqinile, kwaye kulula ukuyondla.

Isicelo

I-1. Intsimi yoNxibelelwano: RF Highnnna esetyenziselwa unxibelelwano olufutshane noltra Wit, olunjengonxibelelwano lwangaphandle lwerediyo, kwaye inokusetyenziswa njenge-antennas yefowuni yokuphucula imiqondiso yefowuni. Inokwandisa uluhlu lokugubungela kwaye iphucule amandla esini
2. Kwindawo yosasazo kunye nomabonwakude, i-microwave phunna isetyenziswa njenge-TV efumana i-eriyali, enokufumana imiqondiso yomabonwakude ngendlela yokwamkela.
I-3. Intsimi ye-radar: Ngenxa yokuhlisela kwaye ufumana iimpawu, ama-millimeter Wave uphonn anokusetyenziselwa ukufumana iithagethi kwiinkqubo ze-radar.
4. Amanye amabala: Mm Wave Honnna unezicelo zeshishini, ukufunyanwa kwedatha kunye neenkqubo zokubeka esweni (i-scada), kunye nezixhobo zokubeka iliso, kunye nokuhanjiswa kwesiginali.
I-Yagi Entenna isetyenziswe ngokubanzi kwimimandla yonxibelelwano engenacingo ngenxa yolwakhiwo olulula, iindleko eziphantsi zemveliso, kunye nokusebenza kakuhle.

UmkhubaGcina i-Yagi I-Antentenas igubungela uluhlu lwe-frequency ukuya kuthi ga kwi-173mhz. Sinikezela nge-uphonzy uphondo lwe-uphonnelnnas ye-7DBI, kunye ne-uphondo eliqhelekileyo le-uphondo elihleliweyo le-uphonsias ngokweemfuno zabathengi.
