Yagi antennas rf microwave millimeter wave mm wave
I-Yagi Antenna iyi-antenna ephelile eyakhiwe nge-oscillator esebenzayo (imvamisa i-oscillator egoqiwe), isikejana esingenangqondo, kanye nabaqondisi abambalwa abalandelanayo abahlelwe ngokufana. Ngawo-1920s, Hidetsugu Yagi kanye neTaiki uta kusuka kuTohoku University eJapan basungula le antenna, eyaziwa ngokuthi i- "Yagi UTA Antenna" noma nje "i-antenna".
-Yisimilo
1. Ukuqondisa okuqinile: I-Antenna inokuqondisa okuhle futhi ingagxila kumagagasi omsakazo endaweni ethile. Isiqondisi esikhulu semisebe siyafana naleso somqondisi, ngokucindezela ngempumelelo imfuhlumfuhlu nokuphazanyiswa kwezindlela ezingezona ezihlosiwe.
2. Imali ephakeme: Uma kuqhathaniswa nezimpondo ze-dipole, i-antenna yophondo inenzuzo ephezulu futhi ingabamba kangcono amasiginali akude, yenza ngcono ikhwalithi yokwamukela nokucaca.
I-3. Isakhiwo esilula: Iqanjwe ama-oscillators asebenzayo, ama-melilla asebenzayo, futhi abaqondisi abaningana abangenayo bahlelwe ngokufana, izinto zokwakha kulula ukuzithola, izindleko ziphansi, futhi zilula, futhi kulula ukuzondla.
Isicelo
1. Insimu Yezokuxhumana: I-RF Horn Antenna esetshenziselwa ukuxhumana kwe-Shortwave kanye ne-Ultra Shortwave Communication, njengokuxhumana kwebanga elide, futhi nakho kungasetshenziswa njengezimpondo zangaphandle zeselula amasiginali wefoni. Kungakhulisa ububanzi be-Coverage futhi kuthuthukise amandla wesiginali kumanethiwekhi we-WI FI, alungele ukuxhuma izakhiwo ezikude noma ukunwebisa ukumbozwa okukhulu.
2. Ensimini yokusakaza nethelevishini, i-microwave uphondo i-antenna ivame ukusetshenziswa njengethelevishini ethola i-antenna, engathola amasiginali wethelevishini ezinkomba ezithile futhi athuthukise umphumela wokwamukela.
I-3. Insimu yeRadar: Ngenxa yokuqondisa kwayo futhi inzuzo yayo, izici zophondo lwe-millimeter wave antenna zingasetshenziselwa ukuthola amatshe okuhlosiwe ezinhlelweni ze-radar.
4. Ezinye izinkambu: I-MM wave uphondo i-Antenna futhi inezicelo embonini, izinhlelo zokutholwa kwedatha nezinhloso zokuqapha (i-SCADA) phakathi kokutholwa kwemininingwane yesayensi kanye nokuqashelwa kwezinto zokuhlola, kanye nokudluliselwa kanye nokudlulisela kokuhlolwa okuthile kwesayensi.
I-Yagi Antenna isetshenziswe kabanzi emasimini amaningi okuxhumana ngaphandle kwama-wireless ngenxa yesakhiwo sayo esilula, izindleko eziphansi zokwenziwa, kanye nokusebenza okuhle.
QoqaIzimali ze-Yagi antennas zimboza imvamisa zifinyelela ku-173mhz. Sinikezela ngezimali ezijwayelekile zokuphonswa kophondo lwenzuzo 7DBI, kanye nezimpondo ezenziwe ngezifiso zophondo ezinamakhambi ngokuya ngezidingo zamakhasimende.
