Umgaqo wokusebenza kunye nomsebenzi
Njengenxalenye eyimfuneko yonxibelelwano olungenazingcingo, umsebenzi osisiseko we-eriyali kukukhanya kunye nokufumana amaza erediyo.Xa uhambisa, i-high-frequency current iguqulwa ibe ngamaza e-electromagnetic;Ekufumaneni, i-wave iguqulwa ibe yi-high frequency current.
Iindidi ze-eriyali
Kukho iintlobo ezininzi zee-eriyali, kwaye zinokuhlelwa ngokwezi ntlobo zilandelayo: I-eriyali yesiKhululo esiSiseko kunye ne-eriyali ephathwayo ephathwayo yokusetyenziswa okwahlukeneyo inokohlulwa ibe ngamaza amaza, amaza amade, amaza aphakathi, amaza amafutshane, amaza amafutshane kakhulu. kunye nee-eriyali ze-microwave kwiibhendi zamaza okusebenza ezahlukeneyo.Ngokolwalathiso lwalo, lunokwahlulwa lube zii-antenna ze-omnidirectional kunye nezalathiso.
Ungayikhetha njani i-eriyali
Njengenxalenye ebalulekileyo yenkqubo yonxibelelwano, ukusebenza kwe-antenna kuchaphazela ngokuthe ngqo isalathisi senkqubo yonxibelelwano.Umsebenzisi kufuneka anikele ingqalelo ekusebenzeni kwayo kuqala xa ekhetha i-eriyali.Ngokukodwa, kukho imiba emibini, ukhetho lokuqala lohlobo lwe-eriyali;Ikhetho lesibini kukusebenza kombane we-antenna.Ukubaluleka kokukhetha uhlobo lwe-eriyali kukuba: ingaba ipateni ye-eriyali ekhethiweyo iyahlangabezana neemfuno zosasazo lwamaza erediyo kuyilo lwesixokelelwano;Iimfuno zokukhetha ukusebenza kombane we-eriyali zimi ngolu hlobo lulandelayo: Qinisekisa ukuba iinkcukacha zombane ze-eriyali, ezifana ne-frequency bandwidth, gain, and rated power, ziyahlangabezana neemfuno zoyilo lwesistim.Ke ngoko, umsebenzisi ebengcono ukunxibelelana nomenzi xa ekhetha i-eriyali.
Ukufumana i-antenna
Inzuzo yenye yezalathisi eziphambili ze-eriyali.Yimveliso ye-coefficient yolwalathiso kunye nokusebenza kakuhle, kwaye kukubonakaliswa kobukhulu bemitha ye-antenna okanye amaza afunyenweyo.Ukukhetha ubungakanani benzuzo kuxhomekeke kwiimfuno zoyilo lwesixokelelwano sendawo yokugubungela amaza kanomathotholo.Ngamafutshane, phantsi kweemeko ezifanayo, okukhona inzuzo iphezulu, kokukhona umgama wokusasazwa kwamaza kanomathotholo.Ngokubanzi, i-eriyali yesitishi esisezantsi ithatha i-eriyali yenzuzo ephezulu, kwaye i-eriyali yesitishi esiphathwayo ithatha i-eriyali yenzuzo ephantsi.
