I-antenna yophondofuthii-antenna ephindwe kabiliyizinhlobo ezimbili zama-antenna asetshenziswa emikhakheni eyahlukene ngenxa yezici nemisebenzi yawo eyingqayizivele. Kulesi sihloko, sizohlola izici zama-antenna e-horn kanye nama-antenna ane-dual-polarized bese sihlola izinhlelo zokusebenza ezahlukahlukene lapho la ma-antenna evame ukusetshenziswa khona.
I-antenna ye-Horn iyi-antenna eqondisa ngqo esetshenziswa kabanzi ezinhlelweni zokuxhumana ze-microwave kanye ne-radio frequency. Zibonakala ngesimo esiyindilinga noma esiyi-pyramidal, esizivumela ukuthi zikhiphe kahle futhi zamukele amagagasi kagesi. Ama-antenna e-Horn aklanyelwe ukuba ne-bandwidth ebanzi kanye nenzuzo ephezulu, okwenza afaneleke ezokuxhumana ezikude kanye nezinhlelo ze-radar.
Ngakolunye uhlangothi, i-antenna ene-polarized dual-polarized iyi-antenna engathumela futhi yamukele amagagasi omsakazo kuma-polarization amabili ahambisanayo ngesikhathi esisodwa. Lokhu kusho ukuthi ingakwazi ukusingatha kokubili i-polarization evundlile neqondile, ngaleyo ndlela yandisa umthamo wedatha kanye nekhwalithi yesignali ezinhlelweni zokuxhumana.
Enye yezindawo ezibalulekile zokusetshenziswa kwama-antenna e-horn izinhlelo ze-radar. Ngenxa yezimpawu zazo zokuzuza nokuqondisa okuphezulu, ama-antenna e-horn avame ukusetshenziswa ekufakweni kwe-radar ukulawula ithrafikhi yezindiza, ukuqapha isimo sezulu, kanye nokuqapha kwezempi. Amandla awo okudlulisa nokwamukela amaza kagesi ngokunembile amabanga amade awenza abe yingxenye ebalulekile yobuchwepheshe be-radar.
Ngaphezu kwezinhlelo ze-radar, ama-antenna e-horn asetshenziswa nasekuxhumaneni ngesathelayithi. Ububanzi be-bandwidth kanye nokwanda okukhulu kwama-antenna e-horn kuwenza afanelekele ukudlulisa nokwamukela izimpawu ezivela kumasathelayithi asemkhathini. Kungakhathaliseki ukuthi ukusakaza kuthelevishini, ukuxhumana kwe-inthanethi noma izinhlelo zokubeka umhlaba wonke, ama-antenna e-horn adlala indima ebalulekile ekusunguleni izixhumanisi zokuxhumana ezithembekile namasathelayithi.
Ngaphezu kwalokho, ama-antenna e-horn asetshenziswa kabanzi ezinhlelweni zokuxhumana ezingenantambo njengezixhumanisi ze-microwave eziqondile kanye namanethiwekhi endawo angenantambo (ama-WLAN). Ukuqondisa kwawo kanye nokuzuza okuphezulu kuwenza abe ngcono kakhulu ekusunguleni ukuxhumana okungenantambo okude, ikakhulukazi ezindaweni zasemadolobheni nasemakhaya lapho ukuxhumana kwe-line-of-sight kubalulekile khona.
I-RFMISOIzincomo Zochungechunge Lomkhiqizo We-Antenna Yezimpondo:
RM-SGHA430-15（1.70-2.60GHz）
I-RM-BDHA618-10 (6-18GHz)
RM-CDPHA3337-20 (33-37GHz)
Ngokweama-antenna ahlukaniswe kabili, zivame ukusetshenziswa ezinhlelweni zokuxhumana ezingenantambo ezidinga ukudluliswa kwedatha okuphezulu kanye nokuthembeka kwesignali. Isibonelo, kumanethiwekhi eselula, ama-antenna ahlukaniswe kabili asetshenziselwa ukuthuthukisa amandla kanye nokusebenza kweziteshi eziyisisekelo ngokusekela ukudluliswa kwedatha okuningi okufakwayo.ubuchwepheshe (i-MIMO)Ngokuthumela nokwamukela izimpawu ezihlukanisweni ezimbili eziqondile, ama-antenna ahlukaniswe kabili angashintshanisa idatha ngasikhathi sinye, okuthuthukisa ukusebenza kahle kwe-spectral kanye nokumbozwa kwenethiwekhi.
Ngaphezu kwalokho, ama-antenna ahlukaniswe kabili ayizingxenye ezibalulekile ekufundweni kwezinkanyezi zomsakazo kanye nokusetshenziswa kokuzwa okukude. Ayakwazi ukubamba amagagasi omsakazo ahlukaniswe ngokuvundlile nangokuqondile, okuvumela ukutholakala nokuhlaziywa okunembile kwezehlakalo zasezulwini nezendawo ezungezile. Ku-radio astronomy, ama-antenna ahlukaniswe kabili asetshenziselwa ukutadisha izakhiwo ze-polarization zemithombo yendawo yonke, okuhlinzeka ngokuqonda okubalulekile ngesimo semizimba yasezulwini kanye nendawo yonke.
Emkhakheni wokusakaza okungenantambo, ama-antenna ahlukaniswe kabili asetshenziswa ekusakazweni kwethelevishini nasemsakazweni. Ngokusebenzisa ama-antenna ahlukaniswe kabili, abasakazi bangenza ngcono ukusetshenziswa kwe-spectrum yomsakazo futhi bathuthukise ikhwalithi yezimpawu zokusakaza, baqinisekise ukuthi ababukeli bathola ulwazi olungcono lomsindo nokubukwayo.
I-RFMISOIzincomo zochungechunge lomkhiqizo we-antenna yophondo oluphindwe kabili olune-polarized horn:
RM-DPHA6090-16 （60-90GHz）
I-RM-CDPHA3238-21（32-38GHz）
RM-BDPHA083-7（0.8-3GHz）
Ngamafuphi, ama-antenna e-horn kanye nama-antenna ane-dual-polarized ayizingxenye eziguquguqukayo nezibalulekile ezinhlelweni ezahlukahlukene okuhlanganisa izinhlelo ze-radar, ukuxhumana kwesathelayithi, amanethiwekhi angenantambo, i-radio astronomy kanye nokusakaza. Izici zabo ezihlukile kanye namakhono abo kubenza babaluleke kakhulu ekusunguleni izixhumanisi zokuxhumana ezithembekile nezisebenzayo kanye nokuthuthukisa ucwaningo lwesayensi kanye nokusungula izinto ezintsha kwezobuchwepheshe. Njengoba isidingo sama-antenna asebenza kahle siqhubeka nokukhula, ukubaluleka kwama-antenna e-horn kanye nama-antenna ane-dual-polarized kwezokuxhumana zanamuhla kanye nemizamo yesayensi kulindeleke ukuthi kuhlale kubalulekile.
Ukuze ufunde kabanzi ngama-antenna, sicela uvakashele:
