Yuav Ua Li Cas Tsim Dielectric Lim?

Lub Dielectric Filter yog ib qho fiber ntau optical uas xaiv xa ib lub wavelength thiab qhia txog lwm tus raws li kev cuam tshuam hauv cov qauv. Kuj hu ua interference filter. Microwave dielectric teebmeem ceramics txhim kho qhov loj ntawm cov khoom siv thiab ntim ntim ntawm microwave integrated circuits. Vim li no, nws yog dav siv rau lub microwave lim thiab Circuit Court boards nyob rau hauv lub hauv paus chaw nres tsheb ntawm mobile kev sib txuas lus thiab satellite kev sib txuas lus systems tshwj xeeb tshaj yog nyob rau hauv 5G.
Kev tsim kho sai-tsim 5G thev naus laus zis yuav coj ntau qhov chaw lag luam rau 5G hauv paus chaw nres tsheb nrog rau cov lim dielectric rau 5g chaw nres tsheb.

Txoj Cai Tsim

Tus qauv sib luag ntawm lub tshuab lim dielectric resonator [1] yog tshuaj xyuas siv Scattering parameters module ntawm HFWorks los txiav txim siab nws txoj kev hla-band, qhov txo qis hauv thiab tawm ntawm cov qhab, thiab cov hluav taws xob xa hluav taws xob rau ntau zaus. Qhov tshwm sim qhia tau tias muaj kev sib tw zoo meej nrog cov uas tau nthuav tawm hauv [2]. Cov cables muaj ib tug lossy conductor, thiab muaj ib tug Teflon nyob rau hauv ib feem. HF Works muab qhov ua tau rau cov phiaj xwm sib txawv Scattering Parameters ntawm 2D thiab Smith Chart cov phiaj xwm. Tsis tas li ntawd, lub teb hluav taws xob tuaj yeem pom hauv vector thiab fringe 3D daim phiaj rau txhua qhov kev kawm ntau zaus.

Kev simulation

Txhawm rau simulate tus cwj pwm ntawm cov lim dej no (txhim kho thiab rov qab poob ...), peb yuav tsim Kev Tshawb Fawb Txog Kev Tshawb Fawb, thiab qhia meej txog qhov cuam tshuam ntau npaum li cas ntawm cov kav hlau txais xov ua haujlwm (hauv peb cov ntaub ntawv 100 zaus sib npaug ntawm 4 GHz txog 8 GHz. ).

Khoom thiab Khoom siv

Nyob rau hauv daim duab 1, peb tau pom cov qauv discretized ntawm lub dielectric circuit filter nrog coaxial input thiab tso zis couplers. Ob lub dielectric discs ua raws li kev sib txuas resonators xws li tias tag nrho cov cuab yeej dhau los ua cov lim dej zoo bandpass.

Load / Restraint

Ob qhov chaw nres nkoj yog siv rau ntawm ob sab ntawm ob coaxial couplers. Lub ntsej muag hauv qab ntawm lub thawv cua tau raug kho raws li Perfect Electric Boundaries. Cov qauv profits kab rov tav symmetry dav hlau thiab yog li ntawd, peb tsuas yog yuav tsum tau ua qauv ib nrab. Yog li ntawd, peb yuav tsum tshaj tawm tias mus rau HFWorks simulator los ntawm kev siv PEMS ciam teb; seb nws yog PECS lossis PEMS, nyob ntawm kev taw qhia ntawm cov hluav taws xob nyob ze ntawm tus ciam teb ntawm symmetry. Yog tias tangential, ces nws yog PEMS; yog orthogonal ces nws yog PECS.

Meshing

Lub mesh yuav tsum tau tsom mus rau cov chaw nres nkoj thiab PEC ntsej muag. Meshing cov chaw no pab tus neeg daws teeb meem kho nws qhov tseeb ntawm qhov chaw eddy, thiab coj lawv cov ntaub ntawv tshwj xeeb rau hauv tus account.

Cov txiaj ntsig

Ntau yam 3D thiab 2D cov phiaj xwm muaj los siv, nyob ntawm qhov xwm txheej ntawm txoj haujlwm thiab ntawm qhov ntsuas uas tus neeg siv txaus siab rau. Raws li peb tab tom soj ntsuam nrog cov lim simulation, plotting S21 parameter suab zoo li ib txoj haujlwm intuitive.

Raws li tau hais thaum pib ntawm tsab ntawv ceeb toom no, HFWorks cov phiaj xwm nkhaus rau cov hluav taws xob tsis zoo ntawm 2D cov phiaj xwm zoo li ntawm Smith Charts. Cov tom kawg yog qhov tsim nyog rau cov teeb meem sib txuam, thiab muaj feem cuam tshuam ntau dua thaum peb cuam tshuam nrog cov qauv lim. Peb pom ntawm no tias peb muaj cov hlais ntse ntse thiab peb mus txog qhov kev sib cais zoo sab nraud.

Cov phiaj xwm 3D rau cov kev tshawb fawb tawg-tsis suav nrog ntau qhov tsis sib xws: ob daim duab hauv qab no qhia txog kev faib hluav taws xob rau ob zaus (ib qho yog nyob rau hauv lub band thiab lwm qhov yog sab nraum lub band)

Tus qauv tuaj yeem simulated siv lub resonance solver ntawm HFWorks ib yam nkaus. Peb tuaj yeem ntes ntau hom raws li peb xav tau. Nws yog ib qho yooj yim kom tau txais qhov kev tshawb fawb no los ntawm S-Parameter simulated txoj kev kawm: HFWorks tso cai rau luag thiab tso erations kom sai teeb tsa lub resonance simulation. Lub resonance solver yuav siv sij hawm los xav txog tus qauv EM matrix thiab xa ntau yam kev daws teeb meem Eigen. Cov txiaj ntsig tau zoo heev rau cov kev tshawb fawb yav dhau los. Peb qhia ntawm no lub rooj tshwm sim:
