Chomwe chimatchedwa vertically polarized antenna chimatanthawuza mafunde otulutsidwa ndi mlongoti, ndipo mayendedwe ake polarization amakhala ofukula.
Kuwongolera kwa polarization kwa mafunde kumatanthawuza mayendedwe a vector yamagetsi.
Choncho, polarization malangizo a yoweyula ndi ofukula, kutanthauza kuti mayendedwe a magetsi munda vekitala ndi ofukula.
Momwemonso, mlongoti wopingasa polarized amatanthauza kuti mayendedwe a mafunde ndi opingasa, zomwe zikutanthauza kuti gawo lamagetsi la mafunde lomwe limatulutsa limafanana ndi dziko lapansi.
Vertical polarization ndi horizontal polarization ndi mitundu yonse iwiri ya polarization.
Zomwe zimatchedwa polarization zimatanthawuza polarization ya mafunde, ndiko kuti, kuwongolera kwa malo amagetsi kumalo okhazikika. Zokhazikika zikutanthauza kuti sizisintha.
Mlongoti wa circularized polarized antenna imatanthawuza polarization ya mafunde, ndiko kuti, mayendedwe a malo amagetsi, omwe amazungulira pa yunifolomu angular velocity w pamene nthawi ikusintha.
Ndiye kodi polarization yozungulira dzanja lamanzere ndi lamanja imatsimikiziridwa bwanji?
Yankho ndi manja anu.
Tulutsani manja onse awiri kunja, ndi zala zazikulu zolozera komwe kumafalikira, ndiyeno muwone zala zopindika za dzanja zomwe zimazungulira mbali imodzi ndi polarization.
Ngati dzanja lamanja liri lofanana, ndilo polarization yamanja; ngati dzanja lamanzere ndilofanana, ndilo kumanzere kwa polarization.
Kenako, ndigwiritsa ntchito njira kuti ndikufotokozereni. Tsopano tiyerekeze kuti pali mafunde awiri omwe ali ndi polarized mafunde.
Njira imodzi yopangira polarization ndi njira ya x ndipo matalikidwe ake ndi E1; mbali imodzi ya polarization ndi y direction ndipo matalikidwe ndi E2; mafunde onsewa amafalikira motsatira z.
Powonjezera mafunde awiriwa, gawo lonse lamagetsi ndi:
Kuchokera pamndandanda womwe uli pamwambapa, pali zambiri:
(1) E1≠0, E2 = 0, ndiye mayendedwe a polarization a mafunde a ndege ndi x-axis
(2) E1 = 0, E2≠0, ndiye mayendedwe a polarization a mafunde a ndege ndi y-axis
(3) Ngati E1 ndi E2 onse ndi manambala enieni osati 0, ndiye kuti mayendedwe a polarization a mafunde a ndege amapanga ngodya yotsatirayi ndi x-axis:
(4) Ngati pali kusiyana kwa gawo pakati pa E1 ndi E2, monga momwe tawonera m'chithunzichi, mafunde a ndege amatha kukhala mafunde ozungulira omwe ali kudzanja lamanja kapena kumanzere kwa mafunde ozungulira.
Kuti tinyanga zoyimirira zilandire mafunde opingasa, ndi tinyanga zopingasa kuti zilandire mafunde opingasa, mutha kuzimvetsetsa poyang'ana chithunzi chomwe chili pansipa.
Koma bwanji za mafunde ozungulira polarized? Munjira yopezera polarization yozungulira, imapezedwa popanga polarizations ziwiri zofananira ndi magawo osiyanasiyana.
Kuti mudziwe zambiri za antennas, chonde pitani:
