5ghz omni antenna
1.1 Tsanangudzo yeBase Station Antenna Iyo base chiteshi antenna itransceiver inoshandura masaisai anotungamirwa achipararira pamutsetse uye nzvimbo yakavhenekerwa mafungu emagetsi.Inovakwa pa base station.Basa rayo ndere kufambisa masaini emagetsi emagetsi kana kugamuchira masaini.1.2 Kukamurwa kweBase Station Antennas Base chiteshi antenna akakamurwa kuita omnidirectional antennas uye anotungamira antenna zvinoenderana negwara, uye inogona kupatsanurwa kuita imwechete-polarized antennas uye maviri-polarized antenna zvichienderana neiyo polarization maitiro (iyo polarization yeantenna inoreva kutungamira kwesimba remagetsi remunda rinoumbwa kana antenna inopenya. Kana simba remunda wemagetsi Kana gwara riri perpendicular pasi, radio wave inonzi vertical polarized wave;kana simba resimba remagetsi richienderana nepasi, radio wave inonzi horizontal polarization. Dual-polarized antennas akaiswa polarized mune ese ari maviri akachinjika uye akatwasuka nzira.Uye single-polarized antennas ingori yakachinjika kana yakatwasuka).
2.1 Mamiriro uye Chikero cheBase Station Antenna Market Parizvino, nhamba ye4G base zviteshi muChina ingangoita 3.7 miriyoni.Zvinoenderana nezvinodiwa chaizvo zvekutengesa uye tekinoroji maitiro, nhamba ye5G base stations ichave inenge 1.5-2 nguva ye 4G base stations.Huwandu hwe5G base station muChina hunotarisirwa kusvika pa5-7 miriyoni, uye zvinotarisirwa kuti 20-40 miriyoni base station antennas ichadikanwa munguva ye5G.Zvinoenderana neshumo yeAcademia Sinica, saizi yemusika weiyo base station antennas munyika yangu ichasvika 43 bhiriyoni yuan muna 2021 uye 55.4 bhiriyoni yuan muna 2026, ine CAGR ye5.2% kubva 2021 kusvika 2026. Nekuda kwekuchinja kwe base station antenna cycles uye kupfupika kwese kutenderera kwe4G era, kukura kwemusika weantenna mukutanga 4G era mu2014 yakakwira zvishoma. Kubatsirwa nekusimudzira kwakasimba kwe5G, zvinotarisirwa kuti kukura kwekukura kwemusika kunotarisirwa kuwedzera.Zvinotarisirwa kuti saizi yemusika ichasvika 78.74 bhiriyoni yuan muna 2023, iine musanganiswa wepagore kukura kwe54.4%
3.1 Kusvika kweiyo 5G era Kukurumidza kufambira mberi kwe5G kushambadzira ndechimwe chezvinhu zvakakosha zvinokurudzira kuvandudzwa kweiyo base station antenna industry.Hunhu hweiyo base station antenna inobata zvakananga ruzivo rwemushandisi, uye kusimudzirwa kwekutengeserana kwe5G kuchabatsira zvakananga mukusimudzira nekusimudzira indasitiri ye base station antenna.Pakupera kwa2021, huwandu hwe1.425 miriyoni 5G base zviteshi zvakavakwa uye kuvhurwa munyika yangu, uye nhamba yese ye5G base zviteshi munyika yangu inodarika 60% yepasi rose.Chinodiwa chehuwandu hwe base station antennas: Iyo attenuation yesimba reantenna ine hukama neiyo frequency yechiratidzo. 5G antenna simba attenuation yakakwira zvakanyanya kupfuura iyo ye4G.Pasi pemamiriro akafanana, kufukidzwa kwezviratidzo zve5G inongova chikamu chechina cheiyo ye4G.Kuti uwane iyo yakafanana yekuvhara nzvimbo ye4G masaini, yakawedzera base chiteshi dhizaini inodiwa kusangana neIyo chiratidzo chesimba mukati menzvimbo yekuvhara, saka kudiwa kwe base station antennas kuchawedzera zvakanyanya.
4.1 Massive MIMO Technology MIMO tekinoroji ndiyo yakakosha tekinoroji ye4G kutaurirana.Nekuisa akawanda akawanda ekufambisa uye kugamuchira antenna mumidziyo yehardware, masaini akawanda anogona kutumirwa uye kugamuchirwa pakati peantenna akawanda.Pasi pemamiriro ezviwanikwa zvishoma uye simba rekutumira, Kuvandudza chiratidzo chekufambisa kwemhando uye kuwedzera nzira dzekutaurirana. Massive MIMO's hombe yeMIMO tekinoroji, yakavakirwa parutsigiro rwekutanga rweMIMO rwe8 antenna ports chete, inovandudza kuvharika kwetiweki uye kugadzikana nekuwedzera akawanda antennas kuumba spatial dimension zviwanikwa uye kuwedzera system system. Massive MIMO tekinoroji inoisa zvakakwirira zvinodiwa pane base station antennas.Massive MIMO tekinoroji inoda kuisirwa nhamba yakakura kwazvo yakasarudzika antenna munzvimbo ine shoma yemidziyo kuti ive nechokwadi chekuwana uye nekurongeka kunodiwa pakushongedza. Iyi tekinoroji inoda kuti antenna inofanirwa kuve miniaturized, ine yakakwirira yekuzviparadzanisa nevamwe uye humwe hunhu.Parizvino, iyo Massive MIMO antenna tekinoroji inowanzo tora 64-chiteshi mhinduro.4.2 mmWave tekinoroji Nekuda kwehunhu hwepfupi yekuparadzira kureba uye yakanyanya kudzikisira ye5G millimeter mafungu, dense base station dhizaini uye yakakura-antenna array tekinoroji inogona kuve nechokwadi chekufambisa mhando, uye huwandu hwema antenna eimwe base chiteshi huchasvika makumi kana mazana.Iyo yechinyakare passive antenna haishande nekuti chiratidzo chekurasikirwa kwechiratidzo chakakurisa uye chiratidzo hachigone kufambiswa zvakanaka.
