O le antenna spiral planar o se antenna e fa'aaogaina mo le felauaiga ma le mauaina o fa'ailo fa'aeletonika polarized i le vateatea, fa'atasi ai ma uiga ma fa'aoga nei.

Uiga

1. Polarization mode: Planar spiral antenna o loʻo i ai le polarization mode polarization poʻo le faʻaogaina o le lima taumatau.
2. Fa'afetauiga fa'aletonu: O le fa'aogaina o le antenna fa'asolosolo e lelei le fa'atinoina o le fa'aogaina.
3. Fa'atonuga fa'avevela: Antenna o lo'o i ai le fa'atinoga lelei o fa'atonuga fa'aavevela, fa'atasi ai ma le fa'atonuga maualuga o le fa'avevela o lo'o i le itu masani i itu uma e lua o le va'alele ma fa'asalalauina galu fa'asolosolo fa'asolosolo.
4. Uiga e le fa'alagolago i taimi masani: e pei o antenna spiral equiangular, o lona foliga e fuafuaina i le tulimanu ma e le aofia ai le umi laina, o latou uiga e le afaina i suiga o taimi, ma e iai a latou fa'aupuga lautele lautele.

Fa'atatauga

1. Su'esu'ega: Ona o le agavale po'o le lima taumatau polarization mode ma le lelei fa'atonuga fa'atonuga, e mafai ona maua sa'o e antenna pu fa'ailoga electromagnetic i itu fa'apitoa ma polarizations mo le su'esu'eina o fa'asinomaga fa'amoemoe ma fa'apogai fa'ailo.
2. Feso'ota'iga satelite: RF horn antenna e mafai ona fa'aaogaina e fai ma fafaga fa'ameamea mo satelite fa'afofoga, fafaga lelei fa'ailo vaivai satelite maua i meafaigaluega e maua.
3. Isi fanua: Microwave pu antenna o loʻo i ai foʻi faʻaoga i faiga fesoʻotaʻiga ultra wideband, radar militeri, biotechnology, ma isi faʻalapotopotoga, e pei o le aloese mai le faʻalavelave i le va o fesoʻotaʻiga ultra wideband ma faiga fesoʻotaʻiga vaapiapi.

Qualwaveo lo'o tu'uina atu antenna fa'asolosolo fa'apolokalame e fa'apipi'i le va'ava'a e o'o atu i le 40GHz. Matou te ofoina atu antenna pu'e maua masani o le maua 5dB, fa'apea fo'i fa'apitoa fa'aantenna pu polarized lua e tusa ai ma manaoga o tagata fa'atau.
