Siyilwa njani isihluzi seDielectric?

I-Dielectric Filter yi-fiber optical ekhetha ukuhambisa i-wavelength enye kwaye ibonise abanye ngokusekelwe kwi-Interference ngaphakathi kwesakhiwo. Ikwabizwa ngokuba sisihluzo sophazamiseko. Iimpembelelo zedielectric zeMicrowave iiseramikhi ziphucula ubungakanani bezixhobo kunye noxinano lokupakishwa kweesekethe ezidityanisiweyo zemicrowave. Ngenxa yesi sizathu, isetyenziswa ngokubanzi kwizihluzi ze-microwave kunye neebhodi zesekethe kwisikhululo esisisiseko sonxibelelwano oluphathwayo kunye neenkqubo zonxibelelwano lwesathelayithi ngakumbi kwi-5G.
Itekhnoloji ephuhliswe ngokukhawuleza ye-5G iya kuzisa indawo enkulu yentengiso kwisikhululo sesiseko se-5G kunye nesihluzo se-dielectric kwisikhululo sesiseko se-5g.

Umgaqo-siseko woYilo

Imodeli ye-symmetric yesihluzo se-dielectric resonator [1] ihlalutywa kusetyenziswa imodyuli ye-Scattering parameters ye-HFWorks ukumisela i-pass-band yayo, ukuthotyelwa ngaphakathi nangaphandle kwebhendi, kunye nokuhanjiswa kwentsimi yombane kwiifrikhwensi ezahlukeneyo. Isiphumo sibonisa umdlalo ogqibeleleyo kunye nezo zinikezelwe kwi [2]. Iintambo zine-conductor elahlekileyo, kwaye zineTeflon ngaphakathi inxalenye. I-HF Works inika ithuba lokucwangcisa iiParameters ezahlukeneyo zokuScattering kwi-2D kunye ne-Smith Chart yezicwangciso. Ngaphandle koko, indawo yombane inokubonwa kwi-vector kunye ne-fringe ye-3D yeploti yazo zonke iifrikhwensi ezifundiweyo.

Ukulinganisa

Ukulinganisa ukuziphatha kwesi sihluzo (ukufakwa kunye nokubuyisela ilahleko ...), siya kudala i-Scattering Parameters uphononongo, kwaye sicacise uluhlu olufanelekileyo lwamaxesha apho i-eriyali isebenza khona (kwimeko yethu i-100 frequencies isasazwe ngokufanayo ukusuka kwi-4 GHz ukuya kwi-8 GHz. ).

Izinto eziqinileyo kunye nezixhobo

Kumzobo we-1, sibonise imodeli ecacileyo yesihluzo sesiphaluka se-dielectric ngegalelo le-coaxial kunye ne-output couplers. Iidiski ezimbini zedielectric zisebenza njengeresonators ezidityanisiweyo kangangokuba isixhobo sonke sibe sisihluzo somgangatho ophezulu webhendi.

Umthwalo/ Uthintelo

Amazibuko amabini asetyenziswa emacaleni ezibini ezidibanisa i-coaxial. Ubuso obuphantsi bebhokisi lomoya buphathwa njengeMida ePheleleyo yoMbane. Ulwakhiwo lufumana inzuzo kwindiza ye-symmetry ethe tyaba kwaye ke ngoko, kufuneka silinganise isiqingatha esinye kuphela. Ngenxa yoko, kufuneka sibhengeze ukuba kwi-simulator ye-HFWorks ngokufaka imeko yomda we-PEMS; nokuba ngaba i-PECS okanye i-PEMS, kuxhomekeke kwi-orientation yentsimi yombane kufuphi nomda we-symmetry. Ukuba i-tangential, ke yi-PEMS; ukuba i-orthogonal ke yi-PECS.

Meshing

Umnatha kufuneka ugxininiswe kumazibuko kunye nobuso bePEC. Ukudibanisa le miphezulu kunceda isisombululi sisulungekise ukuchaneka kwaso kwiindawo ze-eddy, kwaye zithathele ingqalelo iifom zazo.

Iziphumo

Iindidi ezahlukeneyo ze-3D kunye ne-2D izicwangciso ziyafumaneka ukuze zisetyenziswe, kuxhomekeke kubume bomsebenzi kunye nokuba yeyiphi iparamitha umsebenzisi anomdla kuyo.

Njengoko kukhankanyiwe ekuqaleni kwale ngxelo, i-HFWorks iceba iigophe zeeparamitha zombane kwiiplani ze-2D kunye nakwi-Smith Charts. Le yokugqibela ifaneleke ngakumbi kwimiba ehambelanayo, kwaye ifanelekile ngakumbi xa sijongana noyilo lokucoca. Siqaphela apha ukuba sinamabhendi okudlula abukhali kwaye sifikelela ekubeni sodwa okukhulu ngaphandle kwebhendi.

Iiplani ze-3D zezifundo ze-scattering-parameters zigubungela uluhlu olubanzi lweeparameters: la manani mabini alandelayo abonisa ukuhanjiswa kwentsimi yombane kwiifrikhwensi ezimbini (enye ingaphakathi kwebhendi kwaye enye ingaphandle kwebhendi)

Imodeli inokulinganisa kusetyenziswa isixazululi se-resonance ye-HFWorks nayo. Sinokubhaqa iindlela ezininzi njengoko sinqwenela. Kulula ukufumana uphononongo olunjalo kwi-S-Parameter yokulinganisa uphononongo : I-HFWorks ivumela ukutsala kunye nokulahla i-erations ukuseta ngokukhawuleza ukulinganisa kwe-resonance. Isicombululi seresonance sithathela ingqalelo imodeli ye-EM matrix kwaye sinikezela ngezisombululo ezahlukeneyo zemowudi ye-Eigen. Iziphumo zihambelana kakuhle kakhulu neziphumo zezifundo zangaphambili. Sibonisa apha itheyibhile yeziphumo :
