Emkhakheni wezinhlelo zokuxhumana,uthis idlala indima ebalulekile ekuqinisekiseni ukudluliswa nokwamukela amasignali. Phakathi kwezinhlobo ezahlukahlukene zama-antenna, ama-antenna empondo yenzuzo agqama njengokukhetha okuthembekile nokusebenza kahle kwezinhlelo zokusebenza ezahlukahlukene. Ngenzuzo yabo engaguquki kanye nokukhanya kokukhanya, lolu hlobo lwe-antenna ludume kakhulu kubuchwepheshe bezokuxhumana. Ake sibhekisise imisebenzi, izimo zokusetshenziswa kanye nezinzuzo zezimpondo zokuzuza okujwayelekile.
Imisebenzi kanye nezimo zokusetshenziswa:
Izimpondo zokuzuza ezijwayelekileaklanyelwe ukuhlinzeka ngokufakwa kwesignali okuzinzile nokuthembekile kumasistimu ahlukene okuxhumana. Umsebenzi wayo oyinhloko ukudlulisa nokwamukela amaza kagesi ngokunembe nangempumelelo. Lokhu kuyenza ilungele izinhlelo zokusebenza ezihlukahlukene, okuhlanganisa ukuxhumana kweselula, ukuxhumana okugxilile, ukuxhumana ngesathelayithi, njll. Noma ngabe kusiza ukuxhumeka kwenethiwekhi yeselula okungenazihibe noma ukunika amandla ukudluliswa kwedatha kwezokuxhumana ngesathelayithi, izimpondo ezijwayelekile zophondo lwenzuzo zibonakala ziyizingxenye ezihlukahlukene nezibalulekile esikhathini samanje. ingqalasizinda yezokuxhumana.
Esinye sezici ezibalulekile ze-antenna ye-antenna yophondo yikhono layo lokugcina inzuzo engaguquki kanye nobude bokukhanya. Lesi sici siqinisekisa amandla esignali angaguquki kanye nokufakwa, okuyenza ifaneleke ezimeni lapho ukuxhumana okuthembekile kubalulekile. Ngaphezu kwalokho, i-antenna ephezulu yokudlulisa amandla inika amandla ukusakazwa kwesignali okusebenzayo ebangeni elide, okuyenza ifanelekele izinhlelo zokuxhumana zebanga elifushane kanye nebanga elide.
inzuzo:
Ama-antenna e-standard horn anikezela ngezinzuzo ezimbalwa ezinomthelela ekwamukelweni kwawo okusabalele kubuchwepheshe bezokuxhumana. Okokuqala, inzuzo yayo engaguquki kanye ne-beamwidth inikeza ukusebenza okubikezelwe nokuzinzile, okuvumela ukulawula okunembile kokudluliswa kwesignali nokwamukela. Lokhu kubikezela kubalulekile ekuqinisekiseni ukuxhumana okuthembekile ezindaweni nezimo ezihlukahlukene.
Ngaphezu kwalokho, amandla e-antenna amahle okuvimba ukuphazamiseka ayenza imelane nezinto zangaphandle ezingase ziphazamise ukudluliswa kwesignali. Lokhu kubaluleke kakhulu ezindaweni zokuxhumana eziminyene lapho ukunciphisa ukuphazamiseka kubalulekile ekugcineni ubuqotho besignali. Ngokunciphisa imithelela yokugxambukela kwangaphandle, izimpondo ezijwayelekile zokuzuza zithuthukisa ukuthembeka kukonke kwezinhlelo zokuxhumana.
Kungakhathaliseki ukuthi isetshenziswe ezindaweni zasemadolobheni ezinethrafikhi yesignali ephezulu noma ezindaweni ezikude ezinengqalasizinda elinganiselwe, ukuzivumelanisa nezimo kwe-antenna kuqinisekisa ukusebenza okungaguquguquki ezindaweni ezihlukene. Lokhu kuvumelana nezimo kuyinzuzo enkulu njengoba kuvumela i-antenna ukuthi ihlanganiswe ngaphandle komthungo ezinhlelweni ezihlukahlukene zokuxhumana.
Ngamafuphi, i-antenna ye-antenna ye-horn ejwayelekile iyisixazululo esithembekile nesisebenza kahle sezinhlelo zokuxhumana, esinokufakwa kwesignali okuzinzile, ukusebenza kahle kokudluliselwa kwamandla aphezulu kanye nekhono eliqinile lokulwa nokuphazamiseka. Ukusebenziseka kwayo ngezindlela eziningi kanye nokubikezela kwayo kuyenza ibe yimpahla ebalulekile emkhakheni wobuchwepheshe bezokuxhumana, ihlangabezane nezinhlobonhlobo zezimo zokusetshenziswa nokusebenza okuzinzile. Njengoba isidingo sokuxhumana okungenamthungo, okuthembekile siqhubeka sikhula, ama-antenna ophondo lwenzuzo ahlala eyisinqumo esinconyiwe ukuhlangabezana nalezi zidingo eziguqukayo.
Okulandelayo, ngizokwethula imikhiqizo embalwa ejwayelekile ye-antenna enezimfanelo ezingenhla:
RM-SGHA22-25(33-50GHz)
RM-SGHA19-25(40-60GHz)
I-RM-SGHA10-15(75-110GHz)
I-RM-SGHA5-23(140-220GHz)
RM-I-SGHA3-20(220-325GHz)
Ukuze ufunde kabanzi ngama-antenna, sicela uvakashele:
