Ama-antenna aguqula amasignali kagesi adluliselwa ngamadivayisi abe amaza kagesi ukuze adluliselwe. Ngokuvamile, ama-antenna anomsebenzi wokudlulisa nokwamukela, kodwa ezimweni ezikhethekile, enza kuphela umsebenzi wokwamukela. (njenge-antenna yokusakaza)
Incazelo ye-antenna iyithuluzi elingasakaza ngempumelelo amagagasi kagesi liqonde endaweni ethile noma lithole amagagasi kagesi ngendlela ethile yesikhala.
Umsebenzi we-antenna ukudlulisa noma ukwamukela amagagasi kagesi, kuyilapho futhi inemisebenzi elandelayo eyisisekelo:
1. I-antenna kufanele ikwazi ukuguqula amandla amaningi wamagagasi aqondiswayo abe amandla kazibuthe kagesi. Lokhu okokuqala kudinga ukuthi uthi lwezimpondo lube uhlelo oluhle oluvulekile kazibuthe kagesi, futhi okwesibili ludinga uthi ukuze lufane nesidlulisi noma isamukeli.
2. I-antenna kufanele igxilise amagagasi kagesi ngangokunokwenzeka ohlangothini oluthile, noma ikhulise ukwamukelwa kwamagagasi angenayo ohlangothini oluthile, okungukuthi, isiqondiso kufanele sibe nesiqondiso.
3. I-antenna kufanele ikwazi ukudlulisa noma ukwamukela amaza kagesi nge-polarization ecacisiwe, okungukuthi, i-antenna ine-polarization efanele.
4. Uthilo kufanele lube namabhendi anele okusebenza.
Umgomo we-antenna: I-antenna idlulisa amagagasi kagesi, kanye nomgomo wokukhiqizwa kwamagagasi kagesi:
Ngokombono kaMaxwell we-electromagnetic field theory, inkambu kagesi eshintshayo ikhiqiza inkambu kazibuthe eshintshayo endaweni ezungezile, futhi indawo kazibuthe eshintshayo iphinde ikhiqize inkambu kagesi eshintshayo. Ngale ndlela, inkambu kagesi eshintshayo kanye nensimu yamagnetic eshintshayo incike komunye nomunye, iyajabulisana, ikhiqizwa ngokushintshana, futhi isakaza ngaphandle kwendawo ngesivinini esithile ukusuka eduze kuya kude.
Imikhiqizo yethu edayiswa kakhulu ihlanganisa izinhlobo ezahlukene zeI-ONUimikhiqizo yochungechunge, kuhlanganise ne-ACI-ONU/ukuxhumanaI-ONU/ehlakaniphileI-ONU/ibhokisiI-ONU, njll. KonkeI-ONUimikhiqizo yochungechunge ingasetshenziselwa izidingo zenethiwekhi ezimeni ezahlukahlukene.
