Anteenada geeska laba-foorka leh waxay gudbin kartaa oo heli kartaa hirarka elektromagnetic-ga ee si toosan u kala qaybsan iyo kuwa toosan ee kala qaybsan iyadoo ilaalinaysa xaaladda booska aan isbeddelin, si khaladka leexashada booska nidaamka uu sababay beddelka booska anteenada si loo daboolo shuruudaha beddelka kala-foorka la tirtiro, iyo si saxnaanta nidaamka loo horumariyo. Anteenada geeska laba-foorka leh waxay leedahay faa'iidooyinka faa'iidada sare, toosinta wanaagsan, go'doominta kala-foorka sare, awoodda awoodda sare, iwm., waxaana si ballaaran loo darsay loona isticmaalay. Anteenada laba-foorka leh waxay taageeri kartaa kala-foorka toosan, kala-foorka elliptical iyo qaababka kala-foorka wareegsan.
Habka Hawlgalka:
| Habka Helitaanka |
| • Marka anteenadu hesho qaab mowjad toosan oo toosan oo toosan, dekedda toosan oo keliya ayaa heli karta, dekedda jiiftana waa la go'doomiyaa. • Marka anteenadu hesho qaab mowjad toosan oo toosan oo toosan, dekedda toosan oo keliya ayaa heli karta, dekedda toosanna waa la go'doomiyaa. • Marka anteenadu hesho qaab-dhismeed wareeg ah oo wareegsan ama wareegsan, dekedaha toosan iyo kuwa toosan waxay helaan qaybaha toosan iyo kuwa toosan ee calaamadda, siday u kala horreeyaan. Iyada oo ku xidhan kala-goynta wareegga bidix (LHCP) ama kala-goynta wareegga midig (RHCP) ee qaabka hirarka, waxaa jiri doona marxalad 90-digrii ah oo dib u dhac ah ama u socota dekedaha. Haddii qaabka hirarku si fiican u kala-goyn yahay, baaxadda calaamadda ee ka imanaysa dekedda ayaa isku mid noqon doonta. Iyadoo la adeegsanayo isku-xidhka isku-dhafka ah ee saxda ah (90 digrii), qaybta toosan iyo qaybta toosan ayaa la isku dari karaa si loo soo celiyo qaab-dhismeedka wareegga ama elliptical. |
| Habka Gudbinta |
| • Marka anteenada ay quudiso deked toosan, waxay gudbisaa qaab mowjad toosan oo kala qaybsan. • Marka anteenada ay quudiso dekedda toosan, waxay gudbisaa qaabka hirarka ee khadka toosan. • Marka anteenada lagu shubo dekedaha toosan iyo kuwa toosan iyadoo loo eegayo farqiga wejiga 90-degree, calaamadaha cabirka siman, qaabka hirarka LHCP ama RHCP waxaa loo gudbiyaa iyadoo loo eegayo heerka dib u dhaca ama u dhexeeya labada calaamadood. Haddii baaxadda calaamadaha ee labada dekedood aysan isku mid ahayn, qaabka hirarka kala-goynta ee elliptical-ka ah ayaa la gudbiyaa. |
| Habka Gudbinta |
| • Marka anteenada loo isticmaalo qaabka gudbinta iyo helitaanka, sababtoo ah kala soocidda u dhaxaysa dekedaha toosan iyo kuwa toosan, waxay isku mar gudbin kartaa oo heli kartaa. |
RF MISOWaxay bixisaa laba taxane oo anteenooyin laba-folar ah, mid ku salaysan qaab-dhismeedka afar-geesoodka ah kan kalena ku salaysan Waveguide Ortho-Mode Transducer (WOMT). Waxaa lagu muujiyey Jaantuska 1aad iyo Jaantuska 2aad siday u kala horreeyaan.
Jaantuska 1 Anteenada geeska afargeeslaha ah ee laba-fog leh
Jaantuska 2 Anteenada geeska ee laba-polarized ah oo ku salaysan WOMT
Isku ekaanshaha iyo kala duwanaanshaha labada anteeno waxaa lagu muujiyay Shaxda 1. Guud ahaan, anteenada ku salaysan qaab-dhismeedka afar-geesoodka ah waxay dabooli kartaa baaxadda hawlgalka oo ballaaran, badanaa ka badan xarigga octave, sida 1-20GHz iyo 5-50GHz. Iyada oo leh xirfadaha naqshadeynta ee heerka sare ah iyo hababka farsamaynta saxnaanta sare leh,RF MISOAnteenada laba-geesoodka ah ee aadka u ballaaran ee band waxay u shaqayn kartaa si la mid ah hirarka milimitir ee sare. Baaxadda hawlgalka ee anteenooyinka ku salaysan WOMT waxaa xaddidaya baaxadda hawlgalka ee hagaha hirarka, laakiin faa'iidada, ballaca alwaaxa, wareegyada dhinaca iyo kala-goynta isdhaafka/kala-goynta dekedda-ilaa-dekedda ayaa ka fiicnaan kara. Waqtigan xaadirka ah suuqa, inta badan anteenooyinka laba-geesoodka ah ee ku salaysan WOMT waxay leeyihiin oo keliya 20% baaxadda hawlgalka mana dabooli karaan xadka caadiga ah ee hagaha hirarka. Anteenada laba-geesoodka ah ee ku salaysan WOMT ee loogu talagalayRF MISOwaxay dabooli kartaa xarigga soo noqnoqda ee hagaha hirarka oo dhan, ama xarigga octave-ka. Waxaa jira noocyo badan oo laga dooran karo.
