ANT051 Fa Element Spiral Antenna Array
| Taitai-mw | Folasaga i Fa Element Spiral Antenna Array |
Fa'ailoaina ole Ta'ita'i masini microwave.,(ta'ita'i-mw) fa'afouga aupito lata mai ile fa'atekonolosi antenna - fa'amautu tele-beam helical antenna stereo arrays. O lenei fa'asologa fa'asolosolo ua mamanuina e fa'afouina ai le auala tatou te va'ai ai ma fa'aogaina fa'aoga antenna, fa'aolaina fa'atinoga e le mafaatusalia ma agava'a i se mamanu fa'apitoa ma lelei.
O le fatu o lenei fa'asologa fou o le elemene antenna helical, lea e fa'apipi'iina ma le fa'aeteete i totonu o le fausaga fa'apipi'i. O le fausaga e aofia ai le pito i luga ma le tele o itu, e fesoʻotaʻi taʻitasi i le pito o le pito i luga. O itu o itu lata ane e fesoʻotaʻi foʻi, e fausia ai se faʻaogaina ma le malosi faʻavae mo elemene antenna.
O le mamanu tulaga ese o le fausaga faʻapipiʻi faʻapipiʻi e mafai ai ona tuʻu elemene antenna helical i luga ma itu, faʻateleina le faʻapipiʻiina ma le faʻatinoga. O lenei fa'atulagaga e mafai ai e le fa'aputuga ona fa'aosoina le tele o fa'alava i se fa'ata'ita'iga, fa'apea le fa'aleleia atili o le fa'afeiloa'iga ma le mafai ona fa'asalalauina o le antenna system.
O se tasi o vaega taua o le fausaga faʻapipiʻi faʻapipiʻi o le foliga masani polygonal o le pito i luga, lea e faʻaleleia atili ai le tufatufaina tutusa o elemene antenna ma faʻamalieina le faʻatinoga atoa o le laina. O lenei mea e fa'amautinoa ai e mafai e le fa'asologa ona tu'uina atu le malosi fa'ailo tumau ma fa'atuatuaina i le tele o fa'aoga ma si'osi'omaga.
