I-antenna, engasetshenziswa ukudlulisa amasignali nokwamukela amasignali, iyahlehliswa, inokufana, futhi ingathathwa njenge-transducer, okuyidivayisi yesixhumi esibonakalayo phakathi kwesekhethi nesikhala.Uma isetshenziselwa ukudlulisa amasignali, amasignali kagesi wemvamisa ephezulu akhiqizwa umthombo wesignali aguqulwa abe amaza kagesi esikhaleni futhi akhishelwe ohlangothini oluthile.Lapho esetshenziselwa ukwamukela amasignali, amaza kazibuthe kagesi emkhathini aguqulwa abe amasignali kagesi futhi adluliselwe kumamukeli ngekhebula.
Noma iyiphi i-antenna inamapharamitha wesici angachazwa kahle, angasetshenziswa ukuhlola ukusebenza kwe-antenna, okuhlanganisa amapharamitha wesici sikagesi kanye nemingcele yesici somshini.
Izici zemishini yezimpondo
Isistimu ye-antenna elula noma eyinkimbinkimbi
Ubukhulu bobukhulu
Kungakhathaliseki ukuthi iqinile, ithembekile futhi ilungele ukusetshenziswa
Amapharamitha wokusebenza we-antenna
Ibanga lemvamisa
inzuzo
Isici se-antenna
Umdwebo oqondisayo
amandla

Isilinganiso segagasi lokuma kwe-voltage
Ukuhlukaniswa kwe-antenna
Ama-antenna angahlukaniswa ngezindlela ezahlukahlukene, ikakhulukazi:
Ukuhlukaniswa ngokusetshenziswa: kungahlukaniswa i-antenna yokuxhumana, i-antenna yethelevishini, i-radar antenna nokunye
Ngokuya ngezigaba zebhendi yokusebenza: ingahlukaniswa ibe i-antenna ye-short-wave, i-ultra-short-wave antenna, i-microwave antenna nokunye.
Ngokwesigaba sokuqondisa: ingahlukaniswa i-omnidirectional antenna, i-directional antenna, njll.
Ngokwezigaba zomumo: zingahlukaniswa zibe i-antenna ewumugqa, i-antenna ehleliwe njalonjalo
I-antenna eqondile: Isiqondiso se-antenna sinqunyelwe endaweni evundlile engaphansi kwama-degrees angu-360.
Ama-antenna e-Omnidirectional avame ukusetshenziselwa ukwamukela/ukudlulisa amasignali kuzo zonke izinkomba ngesikhathi esisodwa.Lokhu kungase kufiseleke uma isignali idinga ukwamukelwa/ukudluliselwa kuzo zonke izindawo, njengakwezinye iziteshi zomsakazo ezivamile.Kodwa-ke, kunezimo lapho isiqondiso sesignali saziwa noma sinqunyelwe.Isibonelo, ngesibonakude somsakazo, kuyaziwa ukuthi amasignali azotholwa ngendlela ethile (esuka emkhathini), kuyilapho izimpondo ze-omni-directional zingasebenzi kahle ekucosheni amasignali afiphele ezinkanyezini.Kulokhu, i-antenna eqondisayo enenzuzo ephezulu ye-antenna ingasetshenziswa ukuthola amandla esignali engeziwe endaweni ethile.
Isibonelo se-antenna ebheke kakhulu i-Yagi antenna.Lezi zinhlobo zama-antenna amaza asetshenziswa ukuthumela/ukwamukela amasignali okuxhumana ebangeni elide lapho isiqondiso sesiginali yokufaka noma okuqondiwe kwaziwa.Esinye isibonelo se-antenna ebheke kakhulu i-waveguide gain antenna.Lawa ma-antenna avame ukusetshenziselwa izinhlelo zokusebenza zokuhlola nezokulinganisa, njengalapho kukala ukusebenza kolunye uthi, noma lapho wamukela/uthumela amasiginali ngebhendi yefrikhwensi ye-waveguide ephezulu.Izimpondo eziqondisayo zingabuye zenziwe ngemiklamo yepuleti eliyisicaba elingasindi ukuze lenziwe kalula kuma-substrates e-RF avamile njenge-PCBS.Lawa ma-antenna amapuleti ayisicaba avame ukusetshenziswa kwezokuxhumana ngabathengi nasezimbonini ngenxa yokuthi ashibhile ukuwakhiqiza futhi anesisindo esincane futhi mancane.
