Theanteeno gees laba-fog lehwaxay gudbin kartaa oo heli kartaa hirarka elektaroonigga ah ee toosan ee kala fog iyo kuwa toosan ee kala fog iyadoo la ilaalinayo xaaladda booska oo aan isbeddelin, si qaladka leexashada booska nidaamka uu sababay beddelka booska anteenada si loo daboolo shuruudaha beddelka kala fogaanshaha loo tirtiro, taasoo hagaajinaysa saxnaanta nidaamka. Anteenooyinka geeska ee laba-geesoodka ah waxay leeyihiin faa'iidooyinka faa'iidada sare, toosnaanta wanaagsan, go'doominta kala fogaanshaha sare, iyo awoodda awoodda weyn, waxaana si ballaaran loo bartay oo loo isticmaalay. Anteenooyinka laba-geesoodka ah ee kala fog waxay taageeri karaan qaababka hirarka toosan, elliptical, iyo wareega ee kala fog.
Habka Shaqada Ugu Muhiimsan:
Habka Helista
• 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 kala qaybsan, dekedda toosan oo keliya ayaa heli karta, dekedda toosanna waa la go'doomiyaa.
• Marka anteenadu hesho qaababka hirarka ee elliptical ama elliptical polarized, dekedaha toosan iyo kuwa toosan waxay helaan qaybaha toosan iyo kuwa jiifa ee calaamadda wareegga ee polarized, siday u kala horreeyaan. Iyada oo ku xidhan polarization-ka wareegga bidix (LHCP) ama polarization-ka wareegga midig (RHCP) ee qaabka hirarka, waxaa jiri doona dib u dhac wejiga 90 darajo ah ama hogaan u dhexeeya dekedaha. Haddii qaabka hirarku si fiican u polarized, baaxadda calaamadaha ee ka imanaya dekedaha ayaa isku mid noqon doonta. Iyadoo la adeegsanayo buundo ku habboon (90 darajo), qaybaha toosan iyo kuwa toosan ayaa la isku dari karaa si loo soo celiyo qaabka hirarka wareegga ama elliptical.
Habka Bilaabidda
• Marka anteenada laga soo geliyo deked toosan, waxaa la gudbiyaa qaab mowjad toosan oo toosan oo kala qaybsan.
• Waxay gudbisaa qaababka hirarka toosan ee toosan marka anteenada laga soo dajiyo dekedda toosan.
• Marka anteenada lagu quudiyo farqiga marxaladda 90 darajo, calaamadaha mugga isku midka ah ee dekedaha toosan iyo kuwa toosan, qaababka hirarka LHCP ama RHCP ayaa la gudbiyaa iyadoo ku xiran dib u dhaca wejiga ama hogaanka u dhexeeya labada calaamadood. Haddii baaxadda calaamadaha ee labada dekedood aysan isku mid ahayn, qaab hirar oo elliptical polarized ah ayaa la gudbiyaa.
Habka Gudbinta
• Marka anteenada loo isticmaalo qaabka gudbinta iyo soo dhoweynta, sababtoo ah kala soocidda u dhaxaysa dekedaha toosan iyo kuwa toosan, gudbinta iyo soo dhoweynta isku mar ayaa suurtogal ah, sida gudbinta toosan iyo soo dhoweynta toosan ee nidaamyada isgaarsiinta.
