Ama-antenna amagagasi e-Millimeter namadivaysi: ukuhlaziywa kwe-panoramic kusuka kubuchwepheshe kuya ekusebenzeni

Kubuchwepheshe bokuxhumana obuthuthukayo, imikhiqizo yamagagasi e-microwave millimeter, njengengxenye ebalulekile yezinhlelo zokuxhumana ezingenazintambo zesimanje, idlala indima ebaluleke kakhulu. Lawa ma-antenna angasebenzi kanye namadivayisi asebenza kubhendi yefrikhwensi ye-4-86GHz awakwazi nje ukuzuza ububanzi obuguquguqukayo obuphezulu kanye nokudluliswa kwesignali ye-broadband, kodwa futhi ahlinzeke ngezixhumanisi zokuxhumana eziphumelelayo ngaphandle kwesidingo samamojula wamandla, abe yinto ebaluleke kakhulu ezinhlelweni zokuxhumana ezingenazintambo ezikhomba-kuya-iphuzu.

Izici zobuchwepheshe zama-antenna namadivaysi e-microwave

Ukuze uqonde imikhiqizo ye-microwave, udinga kuqala ukwazi amagama ayo ayisisekelo kanye nezinkomba zokusebenza. Ezinhlelweni zokuxhumana ezingenazintambo, ukusebenza kwezinti kanye namadivayisi kuthinta ngokuqondile inzuzo, ukusebenza kahle, ukuphazamiseka kwezixhumanisi nempilo yesevisi. Njengokhiye wokuguqulwa kwamandla, izici zemisebe yezimpondo zibaluleke kakhulu, futhi ukulahleka, ukuhlukaniswa nezinye izinkomba zamadivayisi we-microwave akufanele kushaywe indiva lapho kukhethwa. Lezi zinkomba zokusebenza zinquma ngokuhlanganyela ukusebenza kahle okuphelele kohlelo lokuphakela kwe-antenna futhi zithinte amapharamitha afana nenzuzo, iphethini yokuqondisa, kanye nokuhlukanisa phakathi.

Ngokuthuthuka kobuchwepheshe, izimpondo ze-microwave zendabuko zithuthuka kancane kancane zibheke ku-broadband nokusebenza kahle okuphezulu. Izinkampani eziningi zenze izimpondo ze-broadband ezihlangabezana nezidingo zama-bandwidth amakhulu, njenge-antenna engu-20% eyethulwe yi-Tongyu Communications. Ngakolunye uhlangothi, ukuhlukahluka kwezindlela ze-polarization nakho kunikeza ithuba lokuthuthukisa umthamo wesistimu. Ama-antenna ama-microwave ahlukene kabili asetshenziswe kakhulu ezinhlelweni zokuxhumana zama-microwave XPIC.

Izimo zohlelo lwezimpondo ze-microwave namadivayisi

Ama-antenna e-Microwave anezinhlobonhlobo zezimo zohlelo lokusebenza, ezingahlukaniswa kakhulu zibe yizimo zikagesi kanye nezimo zemvelo. Izimo zikagesi zigxile ekwakhiweni kwezixhumanisi zomsakazo, okuhlanganisa i-point-to-point (p2p) kanye ne-point-to-multipoint (p2mp). Izinhlobo ezahlukene zezimpondo zinezidingo ezihlukene zezimpawu zemisebe. Izimo zemvelo zigxile ekubhekaneni nezinselele ezithile zemvelo, ezifana nolwandle olugqwala kakhulu noma izindawo ezithandwa yiziphepho, ezidinga izimpondo ezimelana nokugqwala kanye nezimelana nomoya.

Ezinhlelweni zokuxhumana ezixhumanisa i-microwave, ukufaniswa kwezimpondo nama-transmitters namazamukeli asebenzayo asebenzayo kubalulekile. Abakhiqizi bezintingo bavame ukuhlinzeka ngezixhumi ezithile noma amayunithi oshintsho afana ne-antenna ukuze baqinisekise ukuthi imikhiqizo yabo iyahambisana nemishini yomsakazo evela kubakhiqizi abahlukene, ngaleyo ndlela bathuthukise ukuguquguquka kwemikhiqizo futhi banikeze abasebenzisi ukukhetha okwengeziwe.

Inkomba yentuthuko yesikhathi esizayo

Uma sibheka esikhathini esizayo, ama-antenna we-microwave millimeter wave kanye namadivayisi azothuthuka abheke ukusebenza okuphezulu, izindleko eziphansi, i-multi-polarization, i-broadband, ukusebenza kahle okuphezulu, ukwenza i-miniaturization, ukuhlanganiswa okwenziwe ngokwezifiso kanye nemvamisa ephezulu. Ngokuthandwa kwezinhlelo ze-LTE kanye namanethiwekhi esikhathi esizayo e-5G, amasistimu eziteshi ezincane eziyisisekelo azovame kakhulu, abeke izidingo eziphakeme enombolweni nasekusebenzeni kwezixhumanisi zama-microwave. Ukuze kuhlangatshezwane nezidingo zomkhawulokudonsa wohlelo olukhulayo, ubuchwepheshe be-multi-polarization, i-broadband kanye ne-high-frequency technologies buzothuthukiswa futhi. Ngasikhathi sinye, ukwenziwa kwe-miniaturization kanye nokuhlanganiswa okwenziwe ngendlela oyifisayo kwezinhlelo ze-antenna kuzoba umkhuba wokuthuthuka wesikhathi esizayo ukuze uvumelane nokwehliswa kwevolumu yohlelo kanye nokukhula kwezidingo eziqondene nawe.

Njengesisekelo sezinhlelo zokuxhumana okungenantambo zesimanje, izimpondo ze-microwave millimeter wave kanye namadivayisi azodlala indima ebaluleke kakhulu esikhathini esizayo ngokuthuthukiswa okuqhubekayo kobuchwepheshe kanye nokwanda okuqhubekayo kwemakethe.
