Anteenada geesaha laba-laabantay waxay gudbin kartaa oo heli kartaa mowjadaha korantada ee toosan iyo kuwa toosan iyadoo la ilaalinayo xaaladda booska aan isbeddelin, si qaladka booska booska nidaamka uu keeno beddelka booska anteenada si loo buuxiyo shuruudaha beddelka polarization waa la tirtiray, iyo si saxnaanta nidaamka loo wanaajiyo. Anteenada geesaha laba geesoodka ah waxay leedahay faa'iidooyinka faa'iido sare leh, jiheynta wanaagsan, go'doominta sare, awoodda awoodda sare, iwm., waxaana si ballaaran loo darsay loona adeegsaday. Anteenada laba geesoodka ah waxay taageeri kartaa polarization linear, polarization elliptical iyo mowjadaha polarization wareegyada.
Qaabka Hawlgelinta:
| Qaabka Qaadashada |
| • Marka anteenadu hesho mawjad toosan oo toosan oo toosan ah, waxaa heli karta dekedda toosan oo keliya, dekedduna waa go'doontaa. go'doonsan. • Marka anteenadu hesho qaab mowjad elliptical ama wareeg ah, dekedaha toosan iyo kuwa toosan waxay helayaan qaybaha toosan iyo kuwa toosan ee calaamada, siday u kala horreeyaan. Iyada oo ku xidhan polarization-ka bidix ee wareegtada (LHCP) ama gacanta midig polarization polarization (RHCP) ee waveform, waxaa jiri doona 90-degree weji dib u dhac ama hore u dhexeeya dekedaha. Haddii qaab-dhismeedka mawjaduhu si qumman u siman yahay, baaxadda calaamadda ka imanaysa dekeddu waxay ahaan doontaa isku mid. Adigoo isticmaalaya isku-xidhaha isku-dhafan ee habboon (90 darajo), qaybta toosan iyo qaybta toosan ayaa la isku dari karaa si loo soo celiyo qaab wareeg ah ama qaab mowjad ah. |
| Qaabka Gudbinta |
| • Marka anteenada lagu quudiyo deked toosan, waxay gudbisaa qaab mawjadaha polarization line toosan. • Marka anteenada lagu quudiyo deked toosan, waxay gudbisaa qaab-dhismeedka xariiqda toosan. • Marka anteenada lagu quudiyo dekedaha toosan iyo kuwa toosan ee 90-degree farqi ah, calaamadaha baaxadda siman, mawjada LHCP ama RHCP waxaa lagu kala qaadaa iyadoo loo eegayo marxaladda dib-u-dhaca ama horumarka u dhexeeya labada calaamadood. Haddii baaxadda calaamadaha labada dekedood aysan sinnayn, qaabka hirarka elliptical polarization waa la kala qaadaa. |
| Habka gudbinta |
| • Marka anteenada loo isticmaalo habka gudbinta iyo qaabilaadda, sababta oo ah go'doominta u dhaxaysa dekedaha toosan iyo kuwa toosan, waxay gudbin kartaa oo heli kartaa isku mar. |
RF MISOWaxay bixisaa laba taxane oo anteenooyin laba-laaban leh, mid ku salaysan qaab-dhismeedka afar geesoodka ah iyo kan kale oo ku salaysan Waveguide Ortho-Mode Transducer (WOMT). Waxa lagu muujiyay sawirka 1 iyo sawirka 2 siday u kala horreeyaan.

Jaantus 2 anteeno gees ah oo laba geesood ah oo ku salaysan WOMT
Isku ekaanshaha iyo faraqa u dhexeeya labada anteeno ayaa lagu muujiyay shaxda 1. Guud ahaan, anteenada ku saleysan qaab dhismeedka afar geesoodka ah waxay dabooli kartaa baaxadda ballaaran ee hawlgalka, inta badan in ka badan band octave, sida 1-20GHz iyo 5-50GHz. Iyada oo leh xirfadaha naqshadaynta heersare ah iyo hababka habaynta saxda ah ee saxda ah,RF MISOAnteenada laba-geeska ah ee ultra-ballaaran waxay ka shaqayn kartaa hirarka sare ee hirarka millimitirka. Xadhkaha shaqada ee anteenooyinka ku salaysan WOMT waxa xadiday xadiga hawlgalka ee waveguide, laakiin faa'iidadeeda, ballaca laydhka, lobes-ka iyo kala-soocida iskutallaabtu/go'doominta dekeda-dekedu way fiicnaan kartaa. Waqtigan xaadirka ah suuqa, inta badan anteenooyinka laba-polarized ee ku salaysan WOMT waxay leeyihiin kaliya 20% xadhkaha xadhkaha goosashada mana dabooli karaan heerka guuxa soo noqnoqda ee waveguide. Anteenada ku salaysan WOMT-dual-polarized waxaa naqshadeeyayRF MISOwaxay dabooli kartaa xariiqda soo noqnoqoshada mawjadahan oo buuxa, ama ka sarreeya band octave. Waxaa jira noocyo badan oo laga dooran karo.
