Ua tsaug rau nws cov zog high-zaus, cov qhab-band yog ib txwm siv nyob rau hauv kev sib txuas lus thiab cov xov tooj cua sib txuas lus xws li kev sib txuas lus zoo xws li satellite kev sib txuas lus, cirar, thiab xov tooj cua thiab xov tooj cua astronomy. Txawm li cas los xij, hloov cov paib hauv KA-Band xav tau ntau txoj kev nruj dua tsim qauv tsim qauv rau polarization sib cais thiab pub network.Orthoogonal Hom Transducer(Omt), muaj peev xwm ua tau microwave ua tau, tuaj yeem pab txhawb cov kav hlau txais xov thiab polarization sib cais, kev ua haujlwm zoo heev.
1. Cov txheej txheem tseem ceeb ntawm hom orthogonal qhib
Orthoogonal Hom Transduceryog ib qho cuab yeej siv los cais ob txoj kev sib txuas ua ke polarnation hom, uas feem ntau yog siv hauv lub tub ceev xwm dual-polarization. Nws ua kev ua haujlwm yog muab cais cov lus tawm tswv yim hauv hluav taws xob ua ke ntawm cov khoom siv hluav taws xob hauv hluav taws xob thiab ua tau ntawm cov cim kev sib tw. Txoj kev sib cais no tsis yog tsuas yog ua kom muaj txiaj ntsig los siv cov kev rov siv dua tab sis tseem cuam tshuam txog kev sib txuas lus kev sib txuas lus thiab muaj peev xwm ntawm lub system.
2. Daim ntawv thov ntawm KA-band orthogonal hom transducer
Hauv Ka-Band,Orthoogonal Hom Transducersyog dav siv nyob rau hauv high-userion tshuab. Piv txwv li, hauv kev tsim qauv ntawm cov kav hlau sib dhos hauv Kb Ib qho ntxiv, Orthogonal Hom Transducers kuj tau siv nyob rau hauv KA-Band Satellite kev sib txuas lus cov kev sib txuas lus kom ua tiav kev sib txuas lus tsis zoo los ntawm dual-Polarization pub mis.
3. Tsim thiab Txhim Kho
Txhawm rau kom tau raws li cov yam ntxwv siab ntawm Ka Band, tus qauv tsimOrthoogonal Hom TransducerYuav tsum tau coj mus rau hauv tus account ob qho tib si broadband kev ua tau zoo thiab cov qauv txheej txheem. Piv txwv li, cov qauv hauv Ka band Tsis tas li ntawd, los ntawm kev ua kom zoo dua cov qauv tsim rau kev sib txuas WaveGuide ntev, cov theem sib luag ntawm ob lub orthogonal hom tuaj yeem ua kom tiav, ntxiv txhim kho kev ua haujlwm ntawm transducer.
4. Qhov kev sim thiab kev sim
Cov txiaj ntsig sim qhia tau tias KA-BandOrthoogonal Hom TransducerCov khoom ua pov thawj zoo ua tau kev ua tau zoo nyob rau hauv cov ntau ntawm 26 GHz rau 4 0 ghz. Cov txiaj ntsig kev sim coj tau qhia tias kev xa rov qab ntawm cov coupler tau zoo dua li {2} DB, kev poob qis dua yog tsawg dua 0.4 dB. Cov ntsuas no qhia tau tias lub coupler tuaj yeem ua tau raws li kev xav tau ntawm KA-Band siab sib txuas lus thiab muaj cov nqi engineering ua haujlwm zoo.
5. Yav Tom Ntej Prospections
Nrog rau kev nce ua txuas ntxiv hauv KA-band zaus faib,Orthoogonal Hom Transducersmuaj kev sib txuas lus dav hauv satellite kev sib txuas lus, ci radar, xov tooj cua hnub qub, thiab lwm thaj teb. Kev tshawb fawb yav tom ntej tuaj yeem ua kom zoo dua qub tsim qauv ntawm cov coupler thiab txhim kho nws cov broadband kev ua tau zoo thaum txo cov nqi tsim khoom thiab ua cov khoom raug. Ib qho ntxiv, ua ke nrog cov cuab yeej sim siab tshaj plaws (xws li CST thiab HFSS), kev tsim qauv raug thiab kev ua tau zoo ntawm cov coupler tuaj yeem txhim kho ntxiv.
