Antenna a na-akpọ nke a na-akpọ polarized standard na-ezo aka na ebili mmiri nke antenna na-ewepụta, ebe ntụnye ya na-apụta kwụ ọtọ.
Nduzi polarization nke ebili mmiri na-ezo aka na ntụziaka nke vektọ ubi eletrik.
Ya mere, ntụzịaka polarization nke ebili mmiri ahụ bụ kwụ ọtọ, nke pụtara na ntụzịaka nke vektọ ubi eletrik ahụ bụ kwụ ọtọ.
N'otu aka ahụ, antenna nke nwere polarized kwụ ọtọ pụtara na ntụziaka nke ebili mmiri ahụ kwụ ọtọ, nke pụtara na ntụziaka ọkụ eletrik nke ebili mmiri ọ na-ewepụta dị ka ụwa.
Polarisation kwụ ọtọ na polarisation kwụ ọtọ bụ ụdị polarisation linear.

Ọ bụrụ na aka nri bụ otu, ọ bụ polarization nke aka nri; ọ bụrụ na aka ekpe bụ otu, ọ bụ polarization nke aka ekpe.
Ọzọ, m ga-eji usoro kọwaara gị. Ugbu a, ka e were ya na e nwere ebili mmiri abụọ nwere usoro polarized.
Otu ntụziaka polarization bụ ntụziaka x na njupụta bụ E1; otu ntụziaka polarization bụ ntụziaka y na njupụta bụ E2; ebili mmiri abụọ ahụ na-agbasa n'akụkụ z.
