I-antenna yophondofuthii-antenna ephindwe kabiliizinhlobo ezimbili zezimpondo ezisetshenziswa emikhakheni ehlukahlukene ngenxa yezimpawu nemisebenzi yazo ehlukile. Kulesi sihloko, sizohlola izici zezimpondo zophondo kanye nezimpondo eziphindwe kabili futhi sijule ekusetshenzisweni okuhlukahlukene okuvame ukusetshenziswa kuzo lawa ma-antenna.
I-antenna ye-Horn iyi-antenna eqondisayo esetshenziswa kakhulu kuma-microwave nezinhlelo zokuxhumana zamafrikhwensi omsakazo. Zibonakala ngesimo se-conical noma i-pyramidal, ezivumela ukuthi zikhanyise kahle futhi zithole amagagasi kagesi. Izimpondo zophondo zenzelwe ukuba nomkhawulokudonsa obanzi kanye nenzuzo ephezulu, okuwenza afanelekele ukuxhumana nezinhlelo zerada zebanga elide.
Ngakolunye uhlangothi, i-antenna ene-polarized dual-polarized, iwuthi olungadlulisa futhi lwamukele amaza omsakazo ngokuhlukaniswa kwe-orthogonal okubili ngesikhathi esisodwa. Lokhu kusho ukuthi angakwazi ukuphatha kokubili ukuhlukaniswa okuvundlile nokuqondile, ngaleyo ndlela akhulise umthamo wedatha kanye nekhwalithi yesignali ezinhlelweni zokuxhumana.
Enye yezindawo ezibalulekile zokufakwa kwezimpondo zezimpondo izinhlelo ze-radar. Ngenxa yezinzuzo zabo eziphezulu nezici zokuqondisa, izimpondo zezimpondo zivame ukusetshenziswa ekufakweni kwe-radar ukulawula ukuhamba kwezindiza, ukuqapha isimo sezulu, nokugadwa kwezempi. Ikhono labo lokudlulisa ngokunembile futhi bathole amaza kagesi ebangeni elide libenza babe yingxenye ebalulekile yobuchwepheshe be-radar.
Ngaphezu kwezinhlelo ze-radar, izimpondo zophondo nazo zisetshenziswa kwezokuxhumana ngesathelayithi. Umkhawulokudonsa obanzi nokuzuza okuphezulu kwezimpondo zezimpondo kuzenza zifanelekele ukudlulisa nokwamukela amasignali kumasathelayithi asemkhathini. Noma ngabe ukusakazwa kwethelevishini, ukuxhumana kwe-inthanethi noma izinhlelo zokumisa umhlaba, izimpondo zezimpondo zidlala indima ebalulekile ekusunguleni izixhumanisi zokuxhumana ezinokwethenjelwa namasathelayithi.
Ngaphezu kwalokho, izimpondo zophondo zisetshenziswa kakhulu ezinhlelweni zokuxhumana ezingenazintambo ezifana nezixhumanisi ze-microwave ezikhomba-kuya-ephuzwini kanye namanethiwekhi endawo angenawaya (ama-WLAN). Ukuqondisa kwabo kanye nokuzuza kwabo okuphezulu kubenza balungele ukusungula ukuxhumana okungenazintambo okude, ikakhulukazi ezindaweni zasemadolobheni nezasemaphandleni lapho ukuxhumana okungenantambo kubaluleke kakhulu.
I-RFMISOIzincomo zochungechunge lomkhiqizo we-Horn Antenna:
RM-SGHA430-15 (1.70-2.60GHz)
RM-BDHA618-10(6-18GHz)
RM-CDPHA3337-20 (33-37GHz)
Ngokweama-antenna amabili-polarized, ngokuvamile asetshenziswa ezinhlelweni zokuxhumana ezingenazintambo ezidinga ukudlulisa idatha nokuthembeka kwesignali. Isibonelo, kumanethiwekhi weselula, ama-antenna ane-polarized dual-polarized asetshenziselwa ukuthuthukisa umthamo nokusebenza kweziteshi eziyisisekelo ngokusekela okokufaka okuningi kokuphumayo.(MIMO) ubuchwepheshe. Ngokudlulisa nokwamukela amasignali kuma-orthogonal polarizations amabili, izimpondo ezikabili-polarized zingashintshanisa idatha ngesikhathi esisodwa, zithuthukise ukusebenza kahle kwe-spectral kanye nokufakwa kwenethiwekhi.
Ukwengeza, ama-antenna ane-polarized dual-polarized ayingxenye ebalulekile ku-astronomy yomsakazo nasezinhlelweni zokuzwa ezikude. Ayakwazi ukuthwebula amaza omsakazo avundlile noma mpo, okuvumela ukutholwa okunembayo nokuhlaziya izenzakalo zasezulwini nezemvelo. Ku-astronomy yomsakazo, ama-antenna ane-polarized dual-polarized asetshenziselwa ukutadisha izici ze-polarization zemithombo ye-cosmic, ehlinzeka ngemininingwane ebalulekile mayelana nemvelo yezidalwa zasemkhathini nendawo yonke.
Emkhakheni wokusakaza okungenantambo, izimpondo ezikabili-polarized zisetshenziselwa ukusakaza kukamabonakude wasemhlabeni nomsakazo. Ngokusebenzisa ama-antenna ane-polarized dual-polarized, abasakazi bangathuthukisa ukusetshenziswa kwe-spectrum yomsakazo futhi bathuthukise ikhwalithi yamasiginali okusakaza, baqinisekise okuhlangenwe nakho okungcono komsindo nokubukwayo kwababukeli.
I-RFMISOisincomo sochungechunge lomkhiqizo we-antenna ye-polarized polarized:
RM-DPHA6090-16 (60-90GHz)
RM-CDPHA3238-21 (32-38GHz)
RM-BDPHA083-7(0.8-3GHz)
Kafushane, izimpondo zophondo kanye nezimpondo eziphindwe kabili ziyizingxenye eziguquguqukayo futhi ezibalulekile ezinhlobonhlobo zezinhlelo zokusebenza ezihlanganisa amasistimu e-radar, ukuxhumana ngesathelayithi, amanethiwekhi angenawaya, i-astronomy yomsakazo kanye nokusakaza. Izici namakhono abo ahlukile kubenza babaluleke kakhulu ekusunguleni izixhumanisi zokuxhumana ezinokwethenjelwa nezisebenzayo kanye nokuthuthukisa ucwaningo lwesayensi nokusungula izinto ezintsha zobuchwepheshe. Njengoba isidingo sama-antenna asebenza kahle kakhulu siqhubeka sikhula, ukubaluleka kwezimpondo zezimpondo kanye nezimpondo eziphindwe kabili kwezokuxhumana nemizamo yesayensi kulindeleke ukuthi kuhlale kubucayi.
Ukuze ufunde kabanzi ngama-antenna, sicela uvakashele:
