Ama-antenna namadivayisi e-microwave millimeter wave: ukuhlaziywa kwe-panoramic kusukela kubuchwepheshe kuya kuhlelo lokusebenza

Kubuchwepheshe bokuxhumana obuthuthuka ngokushesha, imikhiqizo yamagagasi e-microwave millimeter, njengengxenye ebalulekile yezinhlelo zokuxhumana ezingenantambo zanamuhla, idlala indima ebaluleke kakhulu. Lawa ma-antenna angasebenzi namadivayisi asebenza kubhendi yemvamisa engu-4-86GHz awakwazi nje kuphela ukufeza ububanzi obuphezulu obuguquguqukayo kanye nokudluliswa kwesignali ye-broadband, kodwa futhi ahlinzeka ngezixhumanisi zokuxhumana ezisebenzayo ngaphandle kwesidingo samamojula wamandla, okuba yinto ebalulekile ezinhlelweni zokuxhumana ezingenantambo eziqondile.

Izici zobuchwepheshe zama-antenna namadivayisi e-microwave

Ukuze uqonde imikhiqizo ye-microwave, okokuqala udinga ukwazi kahle imigomo yayo eyisisekelo kanye nezinkomba zokusebenza. Ezinhlelweni zokuxhumana ezingenantambo, ukusebenza kwama-antenna namadivayisi kuthinta ngqo inzuzo, ukusebenza kahle, ukuphazamiseka kwezixhumanisi kanye nokuphila kwesevisi. Njengesihluthulelo sokuguqulwa kwamandla, izici zokukhanya kwama-antenna zibaluleke kakhulu, futhi ukulahleka, ukuhlukaniswa kanye nezinye izinkomba zamadivayisi e-microwave akufanele kunganakwa lapho kukhethwa. Lezi zinkomba zokusebenza zinquma ngokubambisana ukusebenza kahle kwesistimu yokuphakelwa kwe-antenna futhi zithinta amapharamitha anjengenzuzo, iphethini yokuqondisa, kanye ne-cross-polarization.

Ngokuthuthuka kobuchwepheshe, ama-antenna e-microwave endabuko athuthuka kancane kancane ngendlela ye-broadband kanye nokusebenza kahle okuphezulu. Izinkampani eziningi ziqalise ama-antenna e-broadband ahlangabezana nezidingo zama-bandwidth amakhulu, njenge-antenna ye-broadband engu-20% eyethulwe yi-Tongyu Communications. Ngakolunye uhlangothi, ukuhlukahluka kwezindlela ze-polarization nakho kunikeza ithuba lokuthuthukisa umthamo wesistimu. Ama-antenna e-microwave ane-double-polarized asetshenziswe kabanzi ezinhlelweni zokuxhumana ze-microwave ze-XPIC.

Izimo zokusetshenziswa kwama-antenna namadivayisi e-microwave

Ama-antenna e-microwave anezimo eziningi zokusetshenziswa, ezingahlukaniswa kakhulu ngezimo zikagesi kanye nezimo zemvelo. Izimo zikagesi zigxila ekwakhiweni kwezixhumanisi zomsakazo, okuhlanganisa iphuzu-kuya-ephuzwini (p2p) kanye nephuzu-kuya-ephuzwini eliningi (p2mp). Izinhlobo ezahlukene zama-antenna zinezidingo ezahlukene zezici zokukhanya. Izimo zemvelo zigxile ekubhekaneni nezinselele ezithile zemvelo, njengezindawo ezidla kakhulu ogwini lolwandle noma izindawo ezivame ukuba neziphepho, ezidinga ama-antenna angagqwali futhi angavimbeli umoya.

Ezinhlelweni zokuxhumana nge-microwave link, ukufanisa ama-antenna kanye nama-transmitter nama-receiver asebenzayo angenantambo kubalulekile. Abakhiqizi be-antenna bavame ukuhlinzeka ngezixhumi ezithile noma amayunithi okushintshana afana ne-antenna ukuqinisekisa ukuthi imikhiqizo yabo iyahambisana nemishini yomsakazo evela kubakhiqizi abahlukene, ngaleyo ndlela kuthuthukiswe ukuzivumelanisa nezimo kwemikhiqizo futhi kunikezwe abasebenzisi izinketho eziningi.

Isiqondiso sentuthuko yesikhathi esizayo

Uma sibheka esikhathini esizayo, ama-antenna nama-amadivayisi e-microwave millimeter wave azothuthuka ngendlela yokusebenza okuphezulu, izindleko eziphansi, i-multi-polarization, i-broadband, ukusebenza kahle okuphezulu, i-miniaturization, ukuhlanganiswa okwenziwe ngokwezifiso kanye ne-high frequency. Ngokuthandwa kwezinhlelo ze-LTE namanethiwekhi e-5G esikhathi esizayo, izinhlelo zesiteshi esincane zizovame kakhulu, zibeke izidingo eziphakeme enanini kanye nokusebenza kwezixhumanisi ze-microwave. Ukuze kuhlangatshezwane nezidingo ze-bandwidth yesistimu ekhulayo, ubuchwepheshe be-multi-polarization, i-broadband kanye ne-high-frequency buzothuthukiswa kakhulu. Ngesikhathi esifanayo, i-miniaturization kanye nokuhlanganiswa okwenziwe ngokwezifiso kwezinhlelo ze-antenna kuzoba yindlela yokuthuthukiswa yesikhathi esizayo yokuzivumelanisa nokunciphisa ivolumu yesistimu kanye nokukhula kwezidingo ezenziwe ngokwezifiso.

Njengesisekelo sezinhlelo zokuxhumana ezingenantambo zesimanje, ama-antenna nama-amadivayisi e-microwave millimeter wave azodlala indima ebaluleke kakhulu esikhathini esizayo ngentuthuko eqhubekayo yobuchwepheshe kanye nokwanda okuqhubekayo kwemakethe.
