5ghz i-antenna yonke
1.1 Incazelo ye-Base Station Antenna I-base station antenna iyi-transceiver eguqula amagagasi aqondiswayo asakazeke emugqeni kanye nesikhala samaza kagesi ozibuthe.Yakhiwe esiteshini esiphansi.Umsebenzi wayo ukudlulisa amaza kagesi noma ukwamukela amasignali.1.2 Ukuhlelwa Kwezimpondo Zesizinda Sezimpondo Izimpondo zesiteshi zihlukaniswa zibe izimpondo ze-omnidirectional kanye nezimpondo eziqondisayo ngokuya ngesiqondiso, futhi ingahlukaniswa ngama-antenna ane-polarized single-polarized antennas ngokuhambisana nezici ze-polarization (i-polarization ye-antenna ibhekisela ekuqondeni kwamandla enkundla kagesi akhiwe lapho ithikithi likhipha ukukhanya. Lapho amandla enkundla kagesi Lapho isiqondiso sibheke phansi, igagasi lomsakazo libizwa ngokuthi i-vertical polarized wave;lapho isiqondiso samandla enkundla kagesi sihambisana nomhlabathi, igagasi lomsakazo libizwa ngokuthi i-horizontal polarization. Ama-antenna ane-polarized dual-polarized ahlukaniswa kuzo zombili izikhombisi-ndlela ezivundlile nezime mpo.Futhi ama-antenna ane-polarized single avundlile noma aqondile kuphela).
2.1 Isimo Nesikali Se-Base Station Antenna Market Njengamanje, inani leziteshi ze-4G e-China lilinganiselwa ezigidini ezingu-3.7.Ngokwezidingo zangempela zezohwebo kanye nezici zobuchwepheshe, inombolo yeziteshi eziyisisekelo ze-5G izoba cishe izikhathi ezingu-1.5-2 kuneziteshi eziyisisekelo ze-4G.Inani leziteshi ze-5G e-China kulindeleke ukuthi lifinyelele ezigidini ezingu-5-7, futhi kulindeleke ukuthi ama-antenna asesiteshini ayizigidi ezingu-20-40 azodingeka esikhathini se-5G.Ngokombiko we-Academia Sinica, usayizi wemakethe wama-antenna esiteshi ezweni lami uzofinyelela kuma-yuan ayizigidi eziyizinkulungwane ezingama-43 ngo-2021 kanye nama-yuan ayizigidi eziyizinkulungwane ezingama-55.4 ngo-2026, nge-CAGR ka-5.2% kusukela ngo-2021 kuya ku-2026. Ngenxa yokuguquguquka kwemijikelezo ye-antenna yesiteshi kanye nomjikelezo omfushane ophelele wenkathi ye-4G, usayizi wemakethe ye-antenna ekuqaleni kwe-4G ngo-2014 wenyuka kancane. Ukuzuza ekuthuthukisweni okunamandla kwe-5G, kulindeleke ukuthi izinga lokukhula kosayizi wemakethe likhuphuke.Kulindeleke ukuthi usayizi wemakethe ufinyelele kuma-yuan ayizigidi eziyizinkulungwane ezingama-78.74 ngo-2023, ngenani lokukhula elihlanganisiwe lonyaka lama-54.4%
3.1 Ukufika kwenkathi ye-5G Ukuthuthuka okusheshayo kokuthengiswa kwe-5G kungenye yezinto ezibalulekile ezikhuthaza ukuthuthukiswa kwemboni ye-antenna esiteshini.Ikhwalithi ye-antenna yesiteshi esiyisisekelo ithinta ngokuqondile ulwazi lomsebenzisi, kanye nokukhuthazwa kwezohwebo kwe-5G kuzofaka isandla ngokuqondile ekuthuthukiseni nasekuthuthukisweni kwemboni ye-antenna yesiteshi esiyisisekelo.Ekupheleni kuka-2021, iziteshi eziyisisekelo ze-5G eziyizigidi ezingu-1.425 zakhiwe futhi zavulwa ezweni lami, kanye nenani eliphelele leziteshi eziyisisekelo ze-5G ezweni lami lingaphezu kuka-60% wengqikithi yomhlaba.Isidingo senombolo ye-base station antenna: Ukuncishiswa kwamandla ka-antenna kuhlobene kahle nemvamisa yesiginali. Ukunciphisa amandla e-antenna ye-5G kuphakeme kakhulu kunaleyo ye-4G.Ngaphansi kwezimo ezifanayo, ukumbozwa kwezimpawu ze-5G kuyingxenye yesine kuphela yaleyo ye-4G.Ukuze ufinyelele indawo efanayo yokufaka amasignali e-4G, Isakhiwo sesiteshi sesisekelo esibanzi siyadingeka ukuze kuhlangatshezwane namandla esiginali ngaphakathi kwendawo ekhavayo, ngakho isidingo sama-antenna esiteshi sizokhula kakhulu.
4.1 Ubuchwepheshe obukhulu be-MIMO Ubuchwepheshe be-MIMO buwubuchwepheshe obuwumgogodla wokuxhumana kwe-4G.Ngokufaka ama-antenna amaningi okudlulisa nokwamukela kumishini yehadiwe, amasignali amaningi angathunyelwa futhi amukelwe phakathi kwezimpondo eziningi.Ngaphansi kwesimo sezinsiza ezilinganiselwe ze-spectrum namandla okudlulisa, Thuthukisa ikhwalithi yokudluliswa kwesignali futhi wandise iziteshi zokuxhumana. Ubuchwepheshe obukhulu be-MIMO be-MIMO, obusekelwe ekusekelweni kwe-MIMO kwasekuqaleni kwamachweba angu-8 kuphela, buthuthukisa ukumbozwa kwenethiwekhi nokuzinza ngokwengeza izimpondo eziningi ukuze kwakhe izinsiza zobukhulu bendawo nokwandisa umthamo wesistimu. Ubuchwepheshe obukhulu be-MIMO bubeka izidingo eziphakeme kuma-antenna asesiteshini.Ubuchwepheshe obukhulu be-MIMO budinga ukufakwa kwenani elikhulu lezimpondo ezibekwe zodwa endaweni elinganiselwe yemishini ukuze kuqinisekiswe ukuzuza nokunemba okudingekayo ekwenzeni i-beamform. Lobu buchwepheshe budinga ukuthi i-antenna kufanele yenziwe i-miniaturized, ibe yodwa ephezulu kanye nezinye izici.Njengamanje, ubuchwepheshe be-antenna ye-Massive MIMO ngokuvamile busebenzisa isixazululo samashaneli angama-64.Ubuchwepheshe be-4.2 mmWave Ngenxa yezimpawu zebanga elifushane lokusakazeka kanye nokuncishiswa okukhulu kwamagagasi angamamilimitha ayi-5G, Isakhiwo sesiteshi esiminyene kanye nobuchwepheshe be-antenna enkulu ingaqinisekisa ikhwalithi yokudlulisela, futhi isibalo sezimpondo zesiteshi esisodwa sizofinyelela emashumini noma amakhulu.I-antenna yendabuko yokwenziwa ayisebenzi ngoba ukulahleka kokudluliselwa kwesignali kukhulu kakhulu futhi isignali ayikwazi ukudluliselwa ngokushelela.
