Antena ya nyanga yokhala ndi polarized two-polarized ndi antena yokhala ndi mawonekedwe a polarization awiri omwe amatha kutulutsa ndi kulandira mafunde a wailesi mbali zonse ziwiri zopingasa komanso zoyimirira.
1. Kapangidwe ndi mfundo:
Antena ya nyanga ziwiri yokhala ndi polarization ili ndi ma radiator awiri ofanana ndi nyanga, imodzi yokhala ndi polarization yopingasa ndi inayo yokhala ndi polarization yopingasa. Ma radiator awiriwa adapangidwa bwino ndikusinthidwa kuti azitha kutulutsa ndi kulandira mafunde a wailesi mbali zonse ziwiri zopingasa komanso zopingasa nthawi imodzi. Kapangidwe ndi mfundo ya antenna ya nyanga ziwiri yokhala ndi polarization zimathandiza kuti ikwaniritse mawonekedwe a polarization awiri.
2. Makhalidwe awiri a polarization:
Antena ya nyanga ziwiri yokhala ndi polarized ili ndi makhalidwe awa:
- Polarization yopingasa ndi yopingasa: Ma antenna a nyanga ziwiri amatha kutulutsa ndi kulandira mafunde a wailesi mbali zonse ziwiri zopingasa ndi zopingasa nthawi imodzi. Izi zikutanthauza kuti imatha kuthandizira kutumiza ma signal ndi kulandira njira ziwiri zosiyana za polarization nthawi imodzi.
- Kugawanika kwapadera: Kugawanika kwapadera ndi kowongoka kwa antenna ya nyanga ziwiri zogawanika sikusiyana, ndipo kumatha kusinthidwa ndikukonzedwa payokha ngati pakufunika. Izi zimapangitsa antenna ya nyanga ziwiri zogawanika kukhala yosinthasintha komanso yoyenera kugwiritsa ntchito zinthu zosiyanasiyana komanso zosowa.
- Kuphatikizana kwa polarization: Kuphatikizana kwa polarization yopingasa ndi yopingasa ya ma antenna a horn okhala ndi polarized awiri ndi kogwirizana, ndipo kumatha kupereka chithandizo chabwino cha ma signal ndi magwiridwe antchito olandirira. Pogwiritsa ntchito polarization yopingasa ndi yopingasa, ma antenna a horn okhala ndi polarized awiri amachepetsa zotsatira za kuchepa kwa ma signal ndi kusokoneza kwa multipath.
3. Madera ogwiritsira ntchito:
Ma antenna a nyanga ziwiri amagwiritsidwa ntchito kwambiri m'magawo ambiri olumikizirana opanda zingwe, makamaka m'malo omwe zizindikiro za njira zosiyanasiyana zolumikizirana ziyenera kutumizidwa ndikulandiridwa nthawi imodzi. Nazi zina mwazomwe zimagwiritsidwa ntchito:
- Makina olumikizirana opanda zingwe: Ma antenna a nyanga ziwiri ozungulira angagwiritsidwe ntchito pa ma antenna a siteshoni yapansi, ma netiweki a Wi-Fi, mauthenga a pafoni, ma wailesi, ndi zina zotero. Amapereka chithandizo chabwino cha ma signal ndi magwiridwe antchito olandirira.
- Kulumikizana kwa Satellite: Ma antenna a nyanga ziwiri okhala ndi polarized angagwiritsidwe ntchito m'malo olumikizirana a satellite kuti alandire ndikutumiza zizindikiro za satellite. Makhalidwe a polarization awiriwa amalola antenna kuti igwirizane ndi zofunikira za polarization za ma satellite osiyanasiyana.
- Kuwongolera kutali kwa wailesi: Ma antenna awiri okhala ndi polarized horn angagwiritsidwe ntchito pa zowongolera kutali ndi zida zowunikira kutali kuti apereke kutumiza ndi kulandira ma signal odalirika kwambiri.
4. Ubwino
Antena ya nyanga ziwiri yokhala ndi polarized ili ndi ubwino wotsatira:
- Makhalidwe awiri a polarization: amatha kutumiza ndi kulandira zizindikiro mbali zonse ziwiri zopingasa komanso zoyima nthawi imodzi.
- Kusinthasintha: Kugawanika kwa polarization yopingasa ndi yopingasa kumadalirana ndipo kumatha kusinthidwa ndikukonzedwa payokha malinga ndi zosowa.
- Kuphatikiza polarization: Pogwiritsa ntchito polarization yopingasa komanso yoyimirira, imapereka chithandizo chabwino cha ma signal komanso magwiridwe antchito olandirira.
Komabe, ma antenna a nyanga ziwiri omwe ali ndi polarized ali ndi zofooka zina:
- Kukula kwakukulu: Popeza ma antenna a nyanga ziwiri okhala ndi polarized amafuna ma radiator awiri, akhoza kukhala akuluakulu.
- Kupanga ndi kusintha kovuta: Kapangidwe ndi kusintha kwa ma antenna a nyanga ziwiri ndi kovuta kwambiri ndipo kumafuna mainjiniya akatswiri kuti apange ndikuwongolera.
