- Iyini inzuzo ye-antenna?
I-AntennaInzuzo ibhekisela esilinganisweni sobuningi bamandla esignali ekhiqizwa yi-antenna yangempela kanye neyunithi ekhanyayo efanele endaweni efanayo esikhaleni ngaphansi kwesimo samandla okufaka alinganayo. Ichaza ngobuningi izinga i-antenna ekhipha ngalo amandla okufaka ngendlela egxilile. Inzuzo ngokusobala ihlobene eduze nephethini ye-antenna. Uma i-lobe eyinhloko yephethini incane futhi i-lobe eseceleni incane, kulapho inzuzo iba phezulu khona. Inzuzo ye-antenna isetshenziselwa ukukala ikhono le-antenna lokuthumela nokwamukela izimpawu ngendlela ethile. Ingenye yemingcele ebaluleke kakhulu yokukhetha ama-antenna asesiteshini sesisekelo.
Ngokuvamile, ukuthuthukiswa kwenzuzo kuncike kakhulu ekunciphiseni ububanzi bomsebe wemisebe eqondile ngenkathi kugcinwa ukusebenza kwemisebe eqondene nendawo yonke endizeni evundlile. Ukwanda kwe-antenna kubaluleke kakhulu kwikhwalithi yokusebenza kwezinhlelo zokuxhumana zeselula ngoba kunquma izinga lesignali emaphethelweni weseli. Ukwandisa inzuzo kungandisa ukumbozwa kwenethiwekhi ngendlela ethile, noma kwandise imajini yenzuzo ngaphakathi kobubanzi obuthile. Noma yiluphi uhlelo lweselula luyinqubo enezindlela ezimbili. Ukwandisa inzuzo ye-antenna kunganciphisa ngasikhathi sinye imajini yesabelomali senzuzo yesistimu enezindlela ezimbili. Ngaphezu kwalokho, amapharamitha amele inzuzo ye-antenna yi-dBd kanye ne-dBi. I-dBi iyinzuzo maqondana ne-antenna yomthombo wephuzu, futhi imisebe kuzo zonke izinhlangothi iyafana; i-dBd ihlobene nenzuzo ye-antenna ye-symmetrical array dBi=dBd+2.15. Ngaphansi kwezimo ezifanayo, lapho inzuzo iphakama, ibanga elide amagagasi omsakazo angalisakazeka.
Umdwebo wokuzuza kwe-antenna
Uma ukhetha inzuzo ye-antenna, kufanele inqunywe ngokusekelwe ezidingweni zohlelo lokusebenza oluthile.
- Ukuxhumana kwebanga elifushane: Uma ibanga lokuxhumana lifushane futhi kungekho zithiyo eziningi, ukukhuphuka kwe-antenna ephezulu kungase kungadingeki. Kulokhu, ukukhuphuka okuphansi (njengokukhuphuka kwe-antenna).0-10dB) ingakhethwa.
RM-BDHA0308-8（0.3-0.8GHz，8 Uhlobo.dBi）
Ukuxhumana kwebanga eliphakathi: Ekuxhumaneni kwebanga eliphakathi, kungase kudingeke ukukhuphuka kwe-antenna okumaphakathi ukuze kulungiswe ukuncishiswa kwesignali Q okubangelwa ibanga lokudlulisa, kuyilapho kucatshangelwa nezithiyo ezikumvelo. Kulokhu, ukukhuphuka kwe-antenna kungabekwa phakathi10 kanye no-20 dB.
RM-SGHA28-15(26.5-40 GHz ,15 Uhlobo lwe-dBi)
Ukuxhumana kwebanga elide: Ezimweni zokuxhumana ezidinga ukumboza amabanga amade noma ezinezithiyo eziningi, inzuzo ephezulu ye-antenna ingadingeka ukuze kunikezwe amandla esignali anele ukunqoba izinselelo zebanga lokudlulisa kanye nezithiyo. Kulesi simo, inzuzo ye-antenna ingabekwa phakathi 20 kanye no-30 dB.
RM-SGHA2.2-25(325-500GHz，25 Uhlobo lwe-dBi）
Indawo enomsindo ophezulu: Uma kukhona ukuphazamiseka okukhulu nomsindo endaweni yokuxhumana, ama-antenna anamandla aphezulu angasiza ekuthuthukiseni isilinganiso sesiginali nomsindo ngaleyo ndlela athuthukise ikhwalithi yokuxhumana.
Kufanele kuqashelwe ukuthi ukwanda kokuzuza kwe-antenna kungahambisana nokuzidela kwezinye izici, njengokuqondisa kwe-antenna, ukumbozwa, izindleko, njll. Ngakho-ke, lapho ukhetha ukuzuza kwe-antenna, kubalulekile ukucabangela izici ezahlukahlukene nokwenza izinqumo ezifanele ngokusekelwe esimweni esithile. Umkhuba omuhle kakhulu ukwenza izivivinyo zasensimini noma ukusebenzisa isofthiwe yokulingisa ukuhlola ukusebenza ngaphansi kwamanani ahlukene okuzuza ukuze uthole indawo efaneleka kakhulu yokuzuza kwemvelo.
Ukuze ufunde kabanzi ngama-antenna, sicela uvakashele:
