Antena yotchedwa vertically polarized antenna imatanthauza mafunde otulutsidwa ndi antena, ndipo malangizo ake a polarization ndi olunjika.
Kulunjika kwa polarization kwa mafunde kumatanthauza komwe vekitala yamagetsi imayendera.
Chifukwa chake, njira ya polarization ya mafunde ndi yolunjika, zomwe zikutanthauza kuti njira ya vector yamagetsi ndi yolunjika.
Mofananamo, antenna yopingasa imatanthauza kuti njira ya mafunde ndi yopingasa, zomwe zikutanthauza kuti njira yamagetsi ya mafunde omwe amatulutsa ndi yofanana ndi dziko lapansi.
Polarization yolunjika ndi polarization yopingasa ndi mitundu yonse ya polarization yolunjika.
Chomwe chimatchedwa linear polarization chimatanthauza polarization ya mafunde, ndiko kuti, njira ya magetsi yomwe imaloza mbali yokhazikika. Yokhazikika imatanthauza kuti sidzasintha.
Antena yozungulira yokhala ndi polarized imatanthauza polarization ya mafunde, ndiko kuti, njira ya magetsi, yomwe imazungulira pa liwiro lofanana la angular w pamene nthawi ikusintha.
Ndiye kodi kugawanika kozungulira kwa dzanja lamanzere ndi lamanja kumatsimikiziridwa bwanji?
Yankho lake lili ndi manja anu.
Tulutsani manja onse awiri, zala zawo zazikulu zikuloza mbali ya kufalikira kwa mafunde, kenako onani zala za dzanja lomwe likupindika zikuzungulira mbali yomweyo ndi polarization.
Ngati dzanja lamanja ndi lomwelo, ndiye kuti ndi polarization ya dzanja lamanja; ngati dzanja lamanzere ndi lomwelo, ndiye kuti ndi polarization ya dzanja lamanzere.
Kenako, ndigwiritsa ntchito njira zofotokozera. Tsopano tiyerekeze kuti pali mafunde awiri ozungulira mzere.
Njira imodzi yolumikizirana ndi x ndipo amplitude ndi E1; njira imodzi yolumikizirana ndi y ndipo amplitude ndi E2; mafunde onsewa amafalikira motsatira z.
Poyerekeza ndi mafunde awiriwa, mphamvu yonse yamagetsi ndi:
Kuchokera pa fomula yomwe ili pamwambapa, pali njira zambiri:
(1) E1≠0, E2=0, ndiye kuti njira ya polarization ya mafunde a ndege ndi x-axis
(2) E1=0, E2≠0, ndiye kuti njira ya polarization ya mafunde a ndege ndi y-axis
(3) Ngati E1 ndi E2 zonse ndi manambala enieni osati 0, ndiye kuti njira ya polarization ya mafunde a ndege imapanga ngodya yotsatirayi ndi x-axis:
(4) Ngati pali kusiyana kwa gawo pakati pa E1 ndi E2, monga momwe zasonyezedwera pachithunzi chili pansipa, mafunde a ndege akhoza kukhala mafunde ozungulira ozungulira ozungulira kapena mafunde ozungulira ozungulira ozungulira ozungulira.
Kuti ma antenna ozungulira molunjika alandire mafunde ozungulira molunjika, ndi ma antenna ozungulira molunjika alandire mafunde ozungulira molunjika, mutha kumvetsetsa izi poyang'ana chithunzi chomwe chili pansipa.
Koma bwanji za mafunde ozungulira ozungulira? Pakupanga polarization yozungulira, imapezeka poika ma polarizations awiri olunjika okhala ndi kusiyana kwa magawo.
Kuti mudziwe zambiri zokhudza ma antenna, chonde pitani ku:
