Ihe a na-akpọ antenna polarized kwụ ọtọ na-ezo aka na ebili mmiri nke antenna na-ebupụta, na ntụzịaka polarization ya bụ vetikal.
Ntuziaka polarization nke ebili mmiri na-ezo aka na ntụziaka nke vector mpaghara eletrik.
Ya mere, ntụzịaka polarization nke ebili mmiri ahụ kwụ ọtọ, nke pụtara na ntụzịaka nke vector vector eletrik kwụ ọtọ.
N'otu aka ahụ, antenna nwere polarịịsị anya na-apụta na ntụzịaka nke ebili mmiri dị n'ahịrị, nke pụtara na ntụgharị ọkụ eletrik nke ebili mmiri ọ na-ebunye na-akọrọ na ụwa.
Polarization kwụ ọtọ na kwụ ọtọ bụ ụdị abụọ nke polarization linear.
Ihe a na-akpọ polarization linear na-ezo aka na polarization nke ebili mmiri, ya bụ, ntụziaka nke ọkụ eletrik na-ekwu na ntụziaka edozi. Edoziri pụtara na ọ gaghị agbanwe.

Wepụ aka abụọ ahụ, jiri mkpịsị aka ha na-atụ aka na ntụzịaka mgbasa nke ebili mmiri, wee hụ nke mkpịsị aka gbajiri agbaji na-atụgharị n'otu ụzọ ahụ dị ka polarization.
Ọ bụrụ na aka nri bụ otu, ọ bụ polarization aka nri; ọ bụrụ na aka ekpe bụ otu, ọ bụ polarization aka ekpe.
Ọzọ, m ga-eji usoro kọwaara gị. Ugbu a, ka e were ya na ebili mmiri abụọ nwere akara.
Otu ntụziaka polarization bụ x ntụziaka na njupụta bụ E1; otu polarization direction bụ y direction na njupụta bụ E2; ebili mmiri abụọ ahụ na-agbasa n'akụkụ ụzọ z.
N'ịkwado ebili mmiri abụọ ahụ, mkpokọta ọkụ eletrik bụ:
Site na usoro a dị n'elu, enwere ọtụtụ ohere:
