A I-Antenna Yesiyingi Sokuhlukaniswa Kwesiyingiuhlobo olukhethekile lwe-antenna ye-microwave eklanyelwe ukukhipha noma ukwamukela amagagasi kagesi ane-polarization eyindilinga. Ngokungafani ne-polarization eqondile, lapho insimu kagesi ijikeleza khona endizeni eyodwa, i-polarization eyindilinga ine-vector yensimu kagesi ejikeleza njalo njengoba igagasi lisakazeka, ilandelela iphethini ye-helical. Lesi sici esiyingqayizivele sinikeza izinzuzo ezibalulekile ezindaweni ezahlukahlukene zokuxhumana eziyinselele kanye nokuzwa.
Izinzuzo Eziyinhloko Zokuhlukaniswa Okujikelezayo
1. Ukungavikeleki ekuhlukaniseni izinhlangothi
Ezinhlelweni ze-polarization eziqondile, ama-antenna okudlulisa kanye nama-receiver kumele aqondaniswe kahle ezindizeni zawo ze-polarization ukuze kugwenywe ukulahleka kwesignali. I-polarization eyindilinga iqeda lesi sidingo. Igagasi eliyindilinga eliyindilinga ligcina amandla esignali ahambisanayo kungakhathaliseki ukuthi i-antenna eyamukelayo iqondiswa kanjani—inzuzo ebalulekile yokuxhumana ngesathelayithi yeselula, lapho ukunyakaza kwemoto kushintsha njalo isimo se-antenna.
2. Ukunciphisa Ukuphazamiseka Kwezindlela Eziningi
Uma igagasi eliyindilinga elinobunye livela ebusweni (njengamanzi, izakhiwo, noma umhlabathi), isandla salo sobunye siyaphenduka (isb., isandla sokudla siba sobunxele). Ukwamukela ama-antenna aklanyelwe isandla esisodwa ngokwemvelo kwenqaba isandla esiphambene, kukhansele ngempumelelo izimpawu eziboniswayo ezibangela ukufiphala kwezindlela eziningi. Lesi sici sibaluleke kakhulu kuma-receiver e-GPS kanye nezixhumanisi zokuxhumana zasemadolobheni.
3. Ukungena Ngemiphumela Yomoya
I-polarization eyindilinga ikhombisa ukumelana okuphezulu nokujikeleza kwe-Faraday—into lapho insimu yamagnetic yoMhlaba ijikeleza khona indiza ye-polarization yamagagasi ahlukaniswe ngomugqa adlula ku-ionosphere. Ngokususa ukuzwela ekujikelezeni kwe-polarization, i-polarization eyindilinga iqinisekisa ukudluliselwa kwesignali okuzinzile ezixhumanisini zesathelayithi kuya emhlabathini kanye nokuxhumana okujulile esikhaleni.
4. Ukusebenza Okuthuthukisiwe Esimweni Sezulu Esibi
Imvula, inkungu, kanye neqhwa kubangela ukuncishiswa okuncane kwamagagasi ahlukaniswe ngendilinga uma kuqhathaniswa nokuhlukaniswa okuqondile ngezikhathi ezithile, okwenza ukuhlukaniswa ngendilinga kube ukukhetha okuthandwayo kwezinhlelo ze-radar kanye nezixhumanisi zokuxhumana ezisebenza ezindaweni ezinemvula enkulu.
Ukusetshenziswa kwe-Horn Antenna
Ukuhlukaniswa kwe-circular kuma-antenna e-horn kuvame ukufezwa ngama-polarizers ahlanganisiwe—izakhiwo zemishini ezifana nama-dielectric slabs, ama-corrugations, noma ama-polarizers e-septum abekwe ngaphakathi kwe-waveguide feed. Lezi zingxenye ziguqula okokufaka okune-linearly polarized kube umphumela ohlukaniswe nge-circularly ngokuhlanzeka okuphezulu kanye nokulahlekelwa okuphansi kokufakwa.
Izicelo Ezivamile
•Ukuxhumana Kwesathelayithi: Ama-terminal asemhlabeni kanye nama-antenna asemkhathini athembele ku-polarization eyindilinga ukuze alondoloze ukuzinza kwezixhumanisi naphezu kokunyakaza kwesathelayithi kanye nemiphumela yomkhathi.
•Izinhlelo Zesathelayithi Zokuhamba Komhlaba Wonke (i-GNSS): Izimpawu ze-GPS, i-BeiDou, kanye ne-Galileo zisebenzisa i-polarization eyindilinga ukuqinisekisa indawo ethembekile ezindaweni zasemadolobheni nasezindaweni ezicebile ngezindlela eziningi.
•Izinhlelo zeRadar: I-radar yesimo sezulu kanye ne-radar yokulandelela izinhloso zithola inzuzo ekhonweni le-circular polarization lokuhlukanisa phakathi kwe-clutter yemvula kanye nezinhloso zangempela.
•Impi Yama-elekthronikhi Nokuqaphela: Ukuhlukaniswa okujikelezayo kuvumela amakhono okuvimba aqinile kungakhathaliseki isimo sokuhlukaniswa kwesignali eqondiwe.
•Ukudluliswa Kwamandla Okungenantambo kanye ne-RFID: Kuqinisekisa ukuxhumana okuqhubekayo namathegi ezindaweni ezingahleliwe.
Ama-antenna empondo e-polarization ayindilinga amelela ubuchwepheshe obuvuthiwe kodwa obushintsha njalo, obuletha ukuqina okungenakuqhathaniswa ezindaweni zokusabalala emhlabeni wangempela.I-RFMiso, sihlanganisa ubunjiniyela bokunemba nokulawulwa kwe-polarization okuthuthukisiwe ukuze sinikeze izixazululo zokusebenza okuphezulu ezenzelwe izinhlelo zokusebenza ezidinga kakhulu ezindiza, ezokuvikela kanye nezokuxhumana.
