Antennas amasintha ma siginecha amagetsi otumizidwa ndi zida kukhala mafunde a electromagnetic kuti atumize. Nthawi zambiri, tinyanga zimakhala ndi ntchito yotumizira ndi kulandira, koma mwapadera, zimangogwira ntchito yolandira. (monga mlongoti wowulutsa)
Tanthauzo la mlongoti ndi chipangizo chomwe chimatha kuwunikira bwino mafunde amagetsi kudera linalake la danga kapena kulandira mafunde amagetsi kudera linalake la danga.
Ntchito ya mlongoti ndikutumiza kapena kulandira mafunde a electromagnetic, komanso kukhala ndi ntchito zotsatirazi:
1. Mlongoti uyenera kutembenuza mphamvu zowongoleredwa zowongolera kukhala mphamvu yamagetsi yamagetsi. Izi zimafuna kuti mlongoti ukhale wotseguka bwino wamagetsi, ndipo kachiwiri amafuna mlongoti kuti ufanane ndi chotumizira kapena cholandila.
2. Mlongoti uyenera kuyang'ana mafunde a electromagnetic momwe angathere mbali ina, kapena kukulitsa kuvomereza kwa mafunde obwera mbali ina, ndiko kuti, komweko kumayenera kukhala ndi mayendedwe.
3. Mlongoti uyenera kutumiza kapena kulandira mafunde a electromagnetic polarization, ndiko kuti, mlongoti uli ndi polarization yoyenera.
4. Mlongoti uyenera kukhala ndi ma frequency ogwiritsira ntchito okwanira.
Mfundo ya mlongoti: Mlongoti umatumiza mafunde a electromagnetic, ndi mfundo ya electromagnetic wave generation:
Malinga ndi chiphunzitso cha Maxwell's electromagnetic field theory, kusintha kwa magetsi kumapangitsa kusintha kwa maginito m'malo ozungulira, ndipo kusintha kwa maginito kumapangitsanso kusintha kwa magetsi. Mwa njira iyi, kusintha kwa magetsi ndi kusintha kwa maginito kumadalirana, kukondwera, kupangidwa mosinthana, ndikufalitsa kunja kwa danga pa liwiro linalake kuchokera pafupi ndi kutali.
Zogulitsa zathu zomwe zimagulitsidwa kwambiri zimakhala ndi mitundu yosiyanasiyana yaONUmndandanda wazinthu, kuphatikiza ACONU/ kulumikizanaONU/wanzeruONU/bokosiONU, etc. ZonseONUzogulitsa zotsatizana zitha kugwiritsidwa ntchito pazosowa za netiweki muzochitika zosiyanasiyana.
