Polarizer-ka Hagaha Waveguide: Mabda'a Shaqada, Qodobbada Muhiimka ah iyo Codsiyada

Polarizer-ka hagaha hirarka waa qayb microwave-ka firfircoon ama mawjadaha milimitir-ka ah oo loo isticmaalo in lagu xakameeyo ama lagu beddelo xaaladda kala-goynta ee hirarka elektromagnetic-ka ee ku faafaya nidaamka hagaha hirarka. Waxaa badanaa loo isticmaalaa anteenooyinka geeska, beddelayaasha hagaha hirarka, shabakadaha quudinta, dhammaadka hore ee radar, iyo nidaamyada cabbirka anteenada.

Mid ka mid ah hawlaha ugu badan waa beddelka polarization-ka toosan ilaa wareegsan. Noocan qaab-dhismeedka ah, mowjadda toosan ee polarized-ka ah ee soo socota waxaa loo xalliyaa laba qaybood oo goobta orthogonal ah. Polarizer-ku wuxuu soo bandhigayaa farqi marxaladeed oo la xakameeyey oo u dhexeeya qaybahan si, marka wax soo saarka la soo saaro, ay isugu yimaadaan si ay u sameeyaan polarization-ka wareegsan ee gacanta midig (RHCP) ama polarization-ka gacanta bidix (LHCP).

Nidaamyada laba-wareeg-wareeg ah, qaybtu waxay bixin kartaa waddooyin gaar ah oo loogu talagalay calaamadaha RHCP iyo LHCP. Tusaale ahaan, Polarizer-ka Dual Circular Polarizer ee RF MISO wuxuu ka shaqeeyaa 95 ilaa 105 GHz wuxuuna isticmaalaa hal hage gelinta labajibbaaran oo leh laba hage gelinta hirarka afargeeslaha ah. Qalabku wuxuu taageeraa labadaba RHCP iyo LHCP wuxuuna isticmaalaa is-dhexgalka hage-yaasha hirarka UG-387/UM.

Qodobbada Waxqabadka Muhiimka ah

Dhowr cabbir ayaa si gaar ah muhiim u ah marka la dooranayo polarizer-ka hagaha hirarka.

Kala duwanaanshaha soo noqnoqoshada ayaa go'aamiya baaxadda hawlgalka ee la isticmaali karo ee qaybta.

VSWR waxay tilmaamaysaa sida ugu wanaagsan ee polarizer-ku ula jaanqaado nidaamka mowjadaha ee isku xiran. VSWR-ka hoose guud ahaan wuxuu ka dhigan yahay awood aan si fiican u muuqan.

Saamiga Axial (AR) waa mid ka mid ah tilmaamayaasha ugu muhiimsan ee tayada wareegga-polarization. Saamiga axial ee hooseeya wuxuu matalaa kala-goyn wareeg ah oo wanaagsan. Tusaale ahaan, RM-DCP95105 wuxuu qeexayaa saamiga axial ee ka yar 2 dB iyo VSWR ee ≤1.3 oo ku baahsan xariggeeda la cayimay.

Kala-soocidda waxay qeexeysaa in qalabku uu taageerayo RHCP, LHCP, ama labadaba.

Is-dhexgalka Hagaha Waveguide iyo Nooca Flange-ka ayaa sidoo kale muhiim ah sababtoo ah waxay go'aamiyaan is-waafajinta farsamada iyo RF ee anteenooyinka, beddelayaasha, iyo qaybaha kale ee hagaha mawjadaha.

Adeegsiga Polarizer-ka Waveguide

Polarizer-yada Waveguide-ka waxaa si weyn loogu isticmaalaa:

Nidaamyada anteenada milimitir-hir-mawjadda
Cunnooyinka anteenada geeska ee wareegsan oo si wareeg ah loo kala qaybiyay
Nidaamyada radar
Nidaamyada dayax-gacmeedka iyo isgaarsiinta
Dejinta cabbirka anteenada
Shaybaarka RF iyo nidaamyada microwave-ka
Shabakadaha quudinta hagaha hirarka

Marka la eego mawjadaha millimitir-hirarka, saxnaanta wax soo saarku waxay noqotaa mid aad muhiim u ah sababtoo ah xitaa khaladaadka cabbirka yar yar waxay saameyn karaan dheelitirka wejiga, iswaafajinta is-waafajinta, iyo daahirnimada polarization.

Iyada oo la isku darayo polarizer-ka hagaha hirarka ee si habboon loo qaabeeyey iyo anteeno gees ah oo la jaan qaadi karta ama qaab-dhismeedka quudinta, injineeradu waxay dhisi karaan nidaamyada RF ee wareegsan oo is haysta oo hufan oo loogu talagalay labadaba tijaabinta iyo codsiyada heerka nidaamka.
