O le lua-polarized antenna pu e mafai ona faʻasalalau ma maua faʻalava polarized ma vertically polarized galu electromagnetic ao tausia le tulaga tulaga e le suia, ina ia o le tulaga tulaga sese sese sese e mafua mai i le suia o le tulaga o le antenna ina ia mafai ona ausia manaoga o le suiga polarization ua aveesea, ma ina ia mafai ona faʻaleleia le saʻo o le faiga. O le antenna pu e lua-polarized o loʻo i ai le lelei o le maualuga o tupe maua, faʻatonuga lelei, faʻaesea polarization maualuga, malosi malosi, ma isi, ma ua uma ona suʻesuʻeina ma faʻaaogaina. O le antenna lua-polarized e mafai ona lagolagoina laina polarization, elliptical polarization ma circular polarization waveforms.
Faiga Fa'atino:
| Faiga Mauaina |
| • Pe a maua e le antenna se linearly polarized waveform tuusaʻo, na o le uafu tuusao e mafai ona maua, ma o le uafu faalava ua vavae ese. faaesea. • A maua e le antenna se elliptical po'o le lapotopoto polarization waveform, o le tu'u sa'o ma le fa'alava uafu maua vaega tu'usa'o ma faalava o le faailo, faasologa. Faʻalagolago i le polarization lapotopoto agavale (LHCP) poʻo le polarization lapotopoto taumatau (RHCP) o le galu, o le ai ai se 90-tikeri vaega tuai pe agai i luma i le va o ports. Afai o le waveform e atoatoa circularly polarized, o le a tutusa le amplitude faailo mai le taulaga. E ala i le fa'aogaina o se mea fa'apipi'i sa'o (90 tikeri), e mafai ona tu'u fa'atasi le vaega tu'usa'o ma le vaega fa'ata'atia e toe fa'afo'i ai se fa'ali'oli'o po'o se elliptical waveform. |
| Faiga Fa'asalalau |
| • A fafaga le antenna e se uafu tūsa'o, e fa'asalalauina se laina fa'atūsa'o polarization waveform. • A fafaga le antenna e le uafu faalava, e auina atu le laina faalava polarization waveform. • Pe a fafaga le antenna i le vasa ma fa'alava uafu e se eseesega vaega 90-tikeri, tutusa amplitude faailoilo, o le LHCP po o le RHCP waveform e auina atu e tusa ai ma le vaega tuai pe agai i luma i le va o faailoilo e lua. Afai e le tutusa le amplitudes faailo o ports e lua, o le elliptical polarization waveform e auina atu. |
| Faiga Fa'aliliuina |
| • Pe a faʻaaogaina le antenna i le faʻasalalauga ma le mauaina o le auala, ona o le tuʻueseeseina i le va o vaʻa ma faʻalava, e mafai ona faʻasalalau ma maua i le taimi e tasi. |
RF MISOofoina atu lua faasologa o antenna lua-polarized, tasi e faavae i luga o se fausaga quad-tuaisi ma le isi e faavae i luga o le Waveguide Ortho-Mode Transducer (WOMT). O lo'o fa'aalia i le Ata 1 ma le Ata 2.

O mea tutusa ma eseesega i le va o antenna e lua o loʻo faʻaalia i le Laulau 1. I se tulaga lautele, o le antenna e faʻavae i luga o le fausaga o le quad-ridge e mafai ona ufiufi ai se bandwidth faʻaogaina lautele, e masani lava e sili atu nai lo le octave band, e pei o le 1-20GHz ma le 5-50GHz. Faʻatasi ai ma tomai faʻapitoa faʻataʻitaʻiga ma metotia faʻapipiʻi maualuga,RF MISOO le ultra-wideband dual-polarized antenna e mafai ona galue i ala maualuga o galu milimita. O le faʻaogaina o le bandwidth o antenna faʻavae WOMT e faʻatapulaʻaina e le faʻaogaina o le bandwidth o le galu, ae o lona maua, lautele lautele, lobes itu ma cross polarization / port-to-port isolation e mafai ona sili atu. I le taimi nei i luga o le maketi, o le tele o antenna lua-polarized e faʻavae i luga o le WOMT e naʻo le 20% o le bandwidth faʻaogaina ma e le mafai ona faʻapipiʻiina le faʻaulu masani faʻaulu faʻafefe. O le antenna lua-polarized fa'avae WOMT na mamanuina eRF MISOe mafai ona ufiufi atoa le fa'aili fa'alava fa'asolo, po'o luga o le fa'aili octave. E tele faʻataʻitaʻiga e filifili mai ai.
