Antenna pu'e fa'ata'amiloose antenna e masani ona fa'aogaina i faiga feso'ota'iga uaealesi. O lona faʻavae galue e faʻavae i luga o le faʻalauteleina ma le faʻaogaina o uiga o galu electromagnetic. Muamua, ia malamalama o galu electromagnetic e mafai ona i ai auala eseese polarization, e aofia ai polarization faalava, polarization tūsaʻo ma polarization lapotopoto. Fa'ata'atiaga fa'alava o lona uiga e fa'ata'amilo le ve'a eletise i luga o le itu fa'ata'atia, ma fa'ata'atia fa'asaga i luga o lona uiga o le fa'aola eletise eletise e fa'asolosolo i luga o le itu tu'usa'o. I le polarization lapotopoto, o le oscillation itu i le itu sa'o ma faalava o lo'o i ai i le taimi e tasi, e fai ai se ve'a eletise eletise. Li'o fa'apolarized antenna pu maua circularly polarized radiation o galu electromagnetic e ala i mamanu faapitoa ma fausaga. E masani ona aofia ai se fa'afoliga fa'atusa pu ma se oscillator e feso'ota'i ma le pu. Pe a ulu atu galu electromagnetic i le circularly polarized antenna pu, latou te ulu muamua i le lua e ala i le vibrator. O le mamanu o le oscillator e mafua ai galu electromagnetic e oʻo i le tele o manatunatuga ma refractions i luga o le faʻaaliga i totonu o le ana, lea e mafai ona faʻateleina le faʻaleleia lelei o galu electromagnetic. E ala i le sa'o geometric mamanu ma reflector foliga, o le circularly polarized pu'u antenna e mafai ona fetuutuunai le ala propagation o le galu electromagnetic i le ana e tusa ai ma le tele o le galu electromagnetic ma le tele o le oscillator, ina ia mafai ona maua circularly polarized radiation. O le ta'iala galue o se antenna polarized pu e mafai ona aoteleina e pei o laasaga nei:

O galu eletise e ulu atu i le lua e ala i le vibrator.

O galu eletise e atagia ma faʻafefe i luga o le faʻaaliga i totonu o le ana, ma suia ai lo latou ala faʻasalalau.

A mae'a le tele o manatunatuga ma fa'ata'amiloga, o galu fa'aeletise e fa'atupu fa'alatalata fa'ata'amilo.

O galu eletonika fa'ata'amilomilo e fa'asalalauina i le pu ma fa'aoga mo feso'ota'iga uaealesi.

I se tulaga lautele, o le circularly polarized horn antenna ausia circularly polarized radiation o galu electromagnetic e ala i mamanu faapitoa ma fausaga.O ia antenna e fa'aaogaina lautele i faiga feso'ota'iga uaealesi ma e mafai ona tu'uina atu fa'ailoga fa'amautu ma fa'atuatuaina.
